U.S. national security interests. The semiconductor industry employs a number of strategies to
and Finance

improve the performance and energy efficiency of different types of chips, including creating
chips with denser circuits, new architectures, and new materials. For logic chips (e.g., central

data processing for computing devices), the manufacturing industry has continuously shrunk the
size of key electronic features over the past six decades, using denser circuits to increase
computing power. Certain advanced memory chips (e.g., NAND flash for long-term storage of videos and music) use new
architectures in which manufacturers compete to stack layers of memory cells on top of one another like floors in a building;
the most advanced NAND flash chips have over 200 layers. Next-generation power management chips used in vehicle
electrification increasingly use materials other than silicon, called compound semiconductors, such as silicon carbide.
Another emerging strategy to improve semiconductor device performance is the use of advanced packaging techniques; for
example, stacking chips on top of one another in the same package to improve chip-to-chip communications.
Manufacturers also face ongoing demand for more established products, such as mature generations of chips, the scarcity of
which forced auto manufacturers to temporarily shut down some assembly lines in early 2022. Supply chain resiliency for the
production of mature chip technologies is essential for economic and national security across many sectors, including critical
infrastructure, communications, medical devices, and defense, as well as integration into sophisticated end systems.
The semiconductor supply chain is composed of chip design and fabrication (or manufacturing), as well as assembly, test,
and packaging (ATP) stages to prepare chips for final integration in electronic devices. The semiconductor industry relies on
a wide network of materials, chemicals, gases, and manufacturing equipment suppliers. U.S.-headquartered firms lead in chip
design and manufacturing equipment, accounting for the highest global revenues in 2021 for chip design (46%), as well as in
the production of semiconductor manufacturing equipment (42%) and design software/licensing (72%). A small share of
global manufacturing capacities is physically located in the United States for wafer fabrication (11%) and ATP services (5%);
the majority of fabrication and ATP facilities are located in China, Taiwan, South Korea, and Japan.
The CHIPS Act of 2022 (Division A of P.L. 117-167), signed into law on August 9, 2022, appropriated funding for the
Department of Commerce to carry out the CHIPS for America provisions enacted in the William M. (Mac) Thornberry
National Defense Authorization Act for Fiscal Year 2021 (2021 NDAA, P.L. 116-283). These provisions include $39 billion
in financial incentives to expand domestic manufacturing capacities across the semiconductor supply chain, including for
wafer fabrication, advanced packaging, and semiconductor equipment and materials suppliers. The act also appropriated $11
billion for research and development programs to advance domestic capabilities to produce next-generation semiconductors.
Between 2020 and 2022, U.S.- and foreign-headquartered firms announced over $200 billion in private investments to
expand domestic manufacturing capacities for semiconductor fabrication, equipment, and materials across 16 states. The
Department of Commerce faces choices about how to deploy federal incentives to promote economically viable and
competitive semiconductor technologies. The Department of Commerce anticipates three-quarters of the funds for
semiconductor manufacturing, around $28 billion, will be awarded for facilities fabricating leading-edge logic and memory
chips and the remaining funds for producers of specialty and mature chip technologies, industry suppliers, and ATP facilities.
Funding allocations for different types and generations of chips, as well as different parts of the semiconductor supply chain,
could be a subject of congressional oversight to evaluate the effectiveness of federal awards in promoting technological
leadership, economic security of critical manufacturing industries, and national security.

Semiconductors and the Semiconductor Industry

Introduction
Congress enacted the Creating Helpful Incentives to Produce Semiconductors (CHIPS) for
America program through the William M. (Mac) Thornberry National Defense Authorization Act
for Fiscal Year 2021 (2021 NDAA, P.L. 116-283). It authorized provisions for semiconductor
manufacturing, research and development (R&D), workforce training and education, and
collaboration and coordination with allied and other friendly countries. Subsequently, the CHIPS
Act of 2022 (Division A of P.L. 117-167), signed into law by President Joe Biden on August 9,
2022, appropriated $52.7 billion to carry out these provisions for FY2022-FY2027. It includes
$39 billion in financial incentives to expand domestic manufacturing capacities across the
semiconductor supply chain, including for fabrication and advanced packaging, as well as
suppliers of semiconductor equipment and materials. The act also appropriated $11 billion for
R&D programs to promote U.S. leadership in producing next-generation semiconductor
technologies.
The Department of Commerce faces choices about how to deploy federal incentives to promote
economically viable and competitive semiconductor technologies. Funding allocations for
different types and generations of chips, as well as different parts of the semiconductor supply
chain, could be a subject of congressional oversight to evaluate the effectiveness of federal
awards in promoting technological leadership, economic security of critical manufacturing
industries, and national security. This report on the semiconductor industry discusses the various
types of semiconductor chips, trends in semiconductor design and innovation, the global
landscape of the supply chain, and the competitiveness of the U.S. semiconductor industry to help
inform congressional evaluation of these choices.
Semiconductor Chips
Semiconductors and Their Importance
Semiconductors (also known simply as integrated circuits, microelectronic chips, or computer
chips) are tiny electronic devices (based primarily on silicon or germanium) composed of billions
of components that can process, store, sense, and move data or signals—essentially serving as the
brains, memory, sensors, communications, and power lines of electronic devices. There are a
number of types of chips—including logic, memory, analog, optoelectronics, sensors, and
discretes—each performing different functions and requiring specialized design and
manufacturing processes.
Semiconductors are a uniquely important enabling technology. Fundamental to nearly all modern
industrial and national security activities, semiconductors are also essential building blocks of
other emerging technologies, such as artificial intelligence, autonomous systems, 5G
communications, and quantum computing. For more than six decades, consistent growth in
semiconductor capabilities and performance, along with concurrent cost reductions, has boosted
U.S. economic output and productivity and enabled new products, services, and industries.
The semiconductor industry—and the industrial activities and systems it enables—forms the
foundation of U.S. technological and industrial competitiveness and national security. Many
policymakers see U.S. strength in the domestic production of semiconductors and the retention of
manufacturing knowledge, human expertise, and hands-on experience as vital to U.S. economic
and national security interests.

Semiconductors and the Semiconductor Industry

Semiconductor Chip Types
The semiconductor industry produces a wide variety of chips designed for precise functions,
including processing, storing, sensing, and transmitting data, as well as power management.
Multiple chips are typically integrated together on circuit boards to enable the operation of
electronic devices such as smartphones, computers, and servers. Different types of chips are
typically produced in separate facilities, and often by specialized firms, using unique
manufacturing processes. From 2012 to 2022, global sales of semiconductor chips doubled to
$602 billion to support increasing digitization and connectivity across nearly every industry.1
Recent revenues have been composed mainly of sales of logic, memory, and analog chips (see
Figure 1).2 The remaining sales were for optoelectronics, sensors, and discrete semiconductors.
The largest application markets for semiconductor demand globally in 2022 included
communications (30%), computers (26%), automotive (14%), consumer electronics (14%),
industrial (14%), and government (2%) end uses.3

Logic Chips
Logic chips typically function as the “brains” of computing devices using a binary language (0’s
and 1’s) to process information. Logic chips include microprocessors, such as central processing
units (CPUs) for general-purpose computing and graphics processing units (GPUs) for video
rendering. The logic chip category also includes relatively less expensive microcontrollers, which
are designed to perform a particular task in applications such as power windows and seats in cars.
The use of custom-designed logic chips for special functions like analytics and machine
intelligence—also called accelerators—is also expanding to achieve better performance and
energy efficiency.4 For example, Google and NVIDIA have designed logic chips optimized for

supercomputing and artificial intelligence (AI) applications (sometimes referred to as “AI chips”)
that substantially reduce energy consumption, an important issue for AI and high-performance
computing applications, compared with general-purpose chips.5 The largest applications markets
for logic chips include smartphones, high-performance computing (i.e., supercomputers and
servers), Internet of Things devices (i.e., “smart” devices such as watches, speakers, and
surveillance cameras), and the automotive sector (i.e., advanced infotainment systems and driver
assistance systems).
U.S. Position and Competition in the Global Logic Chip Market
Logic chips accounted for the largest share of total global semiconductor sales in 2021, at about
42% ($232 billion).6 In 2020, about 13% of global logic chip manufacturing capacity was
physically located in the United States, and the majority was located in Taiwan (35%) and China
(23%).7 Most of the logic chip manufacturing facilities (also referred to as fabrication facilities or
“fabs”) owned by firms headquartered in the United States are operated throughout the world by
integrated device manufacturers (IDMs) such as Intel.8 More than 80% of the global capacity for
producing logic chips is owned by contract manufacturers called foundries.9 For the logic chip
foundry segment, U.S. capacity (i.e., foundry capacity physically located in the United States)
accounted for 7% of global foundry capacity in 2020. This capacity is primarily provided through
facilities owned by Global Foundries and Samsung Foundries, with additional foundry capacity
expected to come online by 2025 from Intel and TSMC.10 In 2022, TSMC owned about half of
the global logic chip foundry capacity.11
As of February 2023, two companies, TSMC and Samsung Foundries, had foundries capable of
manufacturing the most advanced generations of logic chip technologies. These include chips
labeled by the industry as 5 nanometer (nm) and 3 nm. These labels are not indicative of the
chip’s size or a physical aspect of the chip. Rather, the labels reflect different generations or
technology nodes, with lower numbers representing more advanced manufacturing capabilities.
Some market analysts project that Intel will begin manufacturing 7 nm chips in 2023 and 5 nm

8 An IDM is a semiconductor company that designs, manufactures, and sells integrated circuit (IC) products. In
contrast, a contract fab, or foundry, manufacturers chips of other companies’ design. Some companies, such as
Samsung, both manufacture their own designs and offer foundry services for other companies. Companies that only
design chips and outsource manufacturing are sometimes referred to as “fabless” companies.

chips in 2024 (or possibly 2023).12 Orders for 3 nm chips reportedly are for logic chips designed
for cryptocurrency mining, mobile phones, and high-performance computing, among other
applications.13 As node sizes have decreased (indicating increased complexity), the cost of
designing logic chips has increased substantially. For example, it cost approximately $51 million
for a single firm to design and prototype 28 nm chips in 2011 and approximately $542 million to
design and prototype 5 nm chips in 2020.14 The United States has historically been the global
leader in logic chip design, with U.S.-headquartered firms accounting for 64% of revenues from
logic chip sales in 2021.15 However, many of these design firms (e.g., AMD, NVIDIA,
Qualcomm, Broadcomm) do not have their own fabrication facilities (they are referred to as
“fabless”) and outsource the production of their designs to foreign-owned foundries located
outside the United States. Only a few other logic chip manufacturers are capable of producing
leading-edge chips, and those are a generation or two behind the 3 nm/5 nm nodes (e.g., U.S.-
based Intel and a China-based foundry, Semiconductor Manufacturing International Corporation
[SMIC]). With export restrictions in place on equipment and software to produce advanced nodes,
SMIC may face challenges in mass producing 7 nm chips at high quality or producing more
advanced nodes.16
Memory Chips
Memory chips store data. The majority of sales for memory chips are for two types of products:
dynamic random access memory (DRAM) and NAND flash.17 DRAM typically holds short-term
data while a device is powered on, such as code needed by a computer processor to run programs;
NAND flash provides long-term storage, such as preserving photos and music, even after a device
is powered off. Over the past decade, the methods used to improve the performance of NAND
flash memory chips have changed. The previous primary strategy to improve semiconductor chip
performance was to shrink two-dimensional (2D) planar devices horizontally. The current
strategy takes a three-dimensional (3D) approach by stacking layers of memory cells on top of
one another, like the floors of a skyscraper. This method improves storage capacity and data
reading/writing speeds without requiring more costly patterning equipment. Further, 3D NAND
can use an older process node between 30 nm and 50 nm, reducing the cost and complexity of

producing smaller features.18 Memory chip makers have competed to increase the number of
layers stacked in a device to bolster the storage capacity of smartphones and solid state drives,
among other applications. The number of layers in 3D devices has increased from 24 layers in
2013 to more than 200 layers as of July 2022.19 Memory chips are more commoditized than logic
chips, using designs that are less application-specific than those used for logic chip production.20
The largest applications markets for memory chips include mobile phones, data centers, and
personal computing devices.21
U.S. Position and Competition in the Global Memory Chip Market
Memory chips accounted for about 28% of global semiconductor sales in 2021 ($154 billion).22
Memory chip manufacturing has seen significant industry consolidation over the past three
decades, in large part due to the tight profit margins in this segment (as is common for
commoditized goods). Most memory chips are commoditized products for broad commercial use
and benefit from economies of scale, creating pressures and incentives for consolidation.23 For
DRAM memory sales, Korean-headquartered Samsung and SK Hynix accounted for more than
70% of market share in 2021; U.S.-based Micron accounted for about 23%.24 Recently, Micron
announced it had started shipment on the most advanced DRAM process technology, called 1-
alpha, with improved memory density and power savings compared with the previous three
generations, which were derivatives of the 10 nm node memory chip.25 For NAND flash memory
sales, Korea-headquartered companies Samsung and SK Hynix and Japan-headquartered Kioxia
accounted for about 53% of market share in 2021, and U.S.-headquartered Western Digital and
Micron accounted for about 33% market share.26 In 2020, Intel sold its flash memory business
(less than 10% of the NAND market), including facilities in China, to SK Hynix.27 Micron,
Samsung, and SK Hynix are competing to mass produce 3D NAND chips with the highest

memory density by producing more than 200 layers per chip. China’s industrial policies have
sought to establish key leaders in the memory chip segment. Since its establishment in 2016,
People’s Republic of China (PRC) chipmaker Yangtze Memory Technologies Corporation
(YMTC) has developed rapidly, reportedly having received $24 billion in subsidies from the PRC
government. In November 2022, a reverse engineering firm claimed that YMTC had used a
unique manufacturing approach to produce an advanced 3D NAND chip with 232 layers
available in commercial products.28 However, with export restrictions in place for NAND flash
chips with 128 layers or more, and the addition of YMTC to the Entity List in December 2022,
YMTC may face steep challenges in expanding manufacturing capacity because of limited access
to U.S. equipment suppliers and services as well as to the U.S. market.29
Analog Chips
Analog chips provide a wide range of functions, including working with sensors to convert and
modify analog signals (e.g., temperature, speed, and pressure, which can span a range of
continuous values) into digital signals used by computers (i.e., discrete values made up of 0’s and
1’s).30 Analog chip applications also include power management designed to convert, control, and
distribute electrical power (e.g., AC to DC power conversion) in, for example, electric vehicles.
Analog chips also are used for communications, including mobile phones (e.g., 5G, Bluetooth,
wireless connectivity) and military detection and surveillance equipment (e.g., radar, sonar,
infrared imaging). Globally, more than half of the analog chip market is for “application-specific”
analog devices that are customized for specific end-users, designed by smaller teams, and
produced in smaller batches compared with the typical high-volume production of commercial
off-the-shelf logic and memory chips. The largest applications market for general-purpose analog
chips in 2022 was power management, and the largest markets for application-specific analog
chips include the communications, automotive, and industrial sectors.31
Next-generation power management and other chips are increasingly being fabricated on
semiconducting materials other than silicon, called wide band-gap or compound semiconductors,
such as silicon carbide (SiC) and gallium nitride (GaN). Power management chips built on wide
band-gap materials enable devices to operate at higher temperatures and voltages with increased
efficiency and reliability.32 The growing production of electric vehicles, along with the need for

increasingly sophisticated systems to integrate renewable power generation into the electric grid,
are likely to increase demand for wide band-gap semiconductors over the coming years. GaN
semiconductors are used in fast-charging applications for consumer electronics, as well as in
aerospace and defense applications, where they show improved reliability in high-radiation
environments compared with silicon-based devices.33
U.S. Position and Competition in the Global Analog Chip Market
Analog chips accounted for about 13% of global semiconductor sales in 2021 ($74 billion).34 The
majority of top analog chip providers by revenue are IDMs that both design and manufacture
their chips in-house. The design and manufacturing of analog chips have experienced less
industry consolidation than the memory segment of the market. Analog chips typically require
specialized designs for different end uses, producing relatively lower volumes of specialized
products fabricated on mature generations of semiconductor. In this market segment, more mature
nodes are not necessarily correlated with less sophisticated chips, highlighting how the potential
complexity or sensitivity of semiconductor chip technology is not necessarily determined solely
by node size. Since 2019, the semiconductor industry has invested more than $15 billion into the
production of SiC semiconductors.35 The leading suppliers of SiC wafers globally are U.S.-based
Wolfspeed and Coherent Corporation (formally known as II-VI Incorporated). Most GaN wafers
are produced in Taiwan.36 In 2021, the three leading analog suppliers globally were U.S. firms:
Texas Instruments, Analog Devices, and Skyworks Solutions. Collectively, these firms accounted
for about 40% of the global market. Other analog suppliers include Europe-based Infineon and
STMicroelectronics, as well as U.S.-based Qorvo, ON Semi, and Microchip.37 Analog suppliers
use a combination of in-house and foundry services to produce their products.
Optoelectronics, Sensors, Discretes (OSD)
Optoelectronic semiconductors are used to interact with or produce light. The largest applications
markets for optoelectronics include light emitting diodes (LEDs); image sensors, such as those
used in cameras; and laser diodes, such as those used in fiber optic communications. Other sensor
applications include semiconductors (often integrating analog components) designed to detect or
control properties such as temperature, pressure, and acceleration. Sensors have a wide array of
applications in consumer electronics (e.g., mobile phones, vehicles, and industrial equipment).
Discrete semiconductors typically perform a single electrical function—for example, controlling

which can improve the efficiency in power electronics by reducing power losses. IEEE, International Roadmap for

using mature node technology.
U.S. Position and Competition in the Global OSD Market
These types of semiconductors collectively accounted for about 17% of global semiconductor
sales in 2021 ($96 billion). The market for these semiconductors is diverse, with many producers
supporting a wide array of end applications. Producers include U.S.-based Diodes Inc., Vishay
Intertechnology, Qorvo, dPix, and Cree. Other leading suppliers include Europe-headquartered
companies ABB Ltd., Infineon Technologies, and STMicroelectronics, and Japan-headquartered
Toshiba.38 China’s industrial policies support national optoelectronic semiconductor champions
such as San’an.39 China’s efforts to acquire foreign semiconductor firms (such as the Chinese
company Nexperia’s attempted bid for U.K.-headquartered Newport Wafer Fab, a transaction
recently blocked by the U.K. government) have sought to advance China’s capabilities in
compound semiconductors with potential power and defense applications.40
Where Different Types of Chips Are Manufactured
The majority of global chip manufacturing capacity in 2020 was owned by firms headquartered in
the United States (22%), South Korea (20%), Taiwan (19%), China (15%), and Japan (12%).41
For the most part, these firms locate their manufacturing facilities in the same set of countries, but
the manufacturing share of different countries varies by chip type (see Figure 2).

Strategies to Improve Semiconductor Performance
The semiconductor industry has improved computational performance over the past six decades,
primarily by steadily reducing the dimensions of key electronic features printed on the chip.
Roughly every two years, the industry has doubled the number of transistors on a given logic chip
area, delivering higher processing power at roughly the same cost. The pace of this innovation is
often referred to as Moore’s law, stemming from an empirical observation first made in 1965 by
Gordon Moore, cofounder of Intel Corporation.
Due to fundamental limitations of reducing a chip’s physical features, which are approaching the
scale of a few atoms, and the high costs and technical difficulties of manufacturing at that scale,
the pace of advancing computing performance using dimensional scaling (i.e., reducing
transistors’ dimensions on a chip)—the underlying expectation of Moore’s law—has been
slowing.42 The cost to produce a 7 nm chip is four times that of a 45 nm chip, and the unit cost of
a chip is expected to be higher at more advanced nodes (e.g., 5 nm and 3 nm).43 Moreover, around
2005, ever-shrinking transistors led to unsustainable power consumption determined by
fundamental device physics.44 As a result, to improve computing performance, the semiconductor
industry began to invest in strategies beyond dimensional scaling, including multicore processors,

44 Leakage current, or current that leaks through the transistor even when it is in an off state, became an issue when the
transistor was shrunk further around 2005, increasing the device power consumption unsustainably and limiting how
much faster the computer could run without overheating.

Semiconductors and the Semiconductor Industry

specially designed chips (in contrast to generic, off-the-shelf chips), new materials and
architectures, and advanced packaging techniques.45
Technology Nodes
Technology node, also referred to as process node, is an industry label that has been used to
define and track successive generations of particular chip technologies over the past six decades.
Node generally represents the size of key electronics on chips measured in metric length; the size
of these features has now reached the scale of nanometers (nm), or one billionth of a meter. For
logic chips, process node has historically been a measurement of transistor gate length (the gate is
what controls the on/off state of the transistor to produce 0’s and 1’s for processing data). For
DRAM memory chips, memory cells are the key electronic features; node sizes are still measured
in nanometers but generally presented using “half-pitch,” or half the distance between adjacent
memory cells. Over time, the size of these features has been continuously reduced, enabling
higher performance by allowing more components on the same chip. As shrinking the electronic
features on chips became increasingly complex and costly for successive nodes, companies added
new strategies to improve chip performance for certain products (e.g., 3D transistor and chip
architectures such as 3D NAND chips, with layers of stacked memory cells, and new materials
like compound semiconductors). Generally, the smaller the node size, the more advanced the
semiconductor technology. However, for some type of chips, process or technology node may not
be the most appropriate metric to capture advancements in performance. Moreover, mature node
semiconductors may be critical components in sophisticated and advanced end systems such as
power management and sensors.
A wide range of nodes is currently in production. For logic chips, these range from the most
advanced 3 nm node, which began production in 2022, to mature generation nodes over 250 nm.46
In 2021, 84% of global semiconductor production capacity was for nodes over 16 nm, according
to one market research firm.47 These mature generations of semiconductors are still in high
demand, especially in fast-growing markets like 5G communications and smart devices. For
example, out of the approximately 170 chips in a smartphone, fewer than 5% are for leading-edge
nodes at 14 nm or below for the processor and memory, with the remainder of legacy chips
providing functionalities for sensors, connectivity, and audio and power management.48
The CHIPS Act of 2022 requires that at least $2 billion of the $19 billion in FY2022 funding
appropriated for semiconductor incentives be used for previous generations of semiconductor
technologies, referred to in the act as “mature technology nodes.” The Secretary of Commerce is
to determine which technology nodes qualify as “mature” for funding purposes. Where to draw
the line between advanced and mature nodes is subjective; there is no industry standard. Further,

45 CPUs originally contained one processor, also called a core, but increasingly have more than one processor, such as
two in dual-core or four in quad-core CPUs. Performance improvements were also enabled by new materials
(germanium, strained silicon, high-K/metal gate) and transistor structures (nonplanar transistors called FinFET) and
placed into high-volume manufacturing by 2011. IEEE, International Roadmap for Devices and Systems, Executive

In September 2022, the Department of Commerce released a strategy document stating that about
three-quarters of the $39 billion in funds appropriated for manufacturing incentives (about $28
billion) will be used for the production of leading-edge chips, while about $10 billion of the
appropriated funds will go toward
 construction or expansion of facilities for the fabrication, packaging, assembly,
and testing of mature- and current-generation chip technologies (including all
types of logic, memory, discrete, analog, and optoelectronic chips);
 facilities to produce new or specialty technologies, such as advanced analog
chips, radiation-hardened chips, compound semiconductors, and emerging
technologies;
 facilities that manufacture equipment and materials for semiconductor
manufacturing; and
 equipment upgrades that provide near-term efficiency improvements in fabs.49

investment credit (AMIC) included in the CHIPS Act of 2022 will generate significant additional
investment for participants.
Advanced Packaging
Advanced packaging includes many different innovative techniques to improve chip-to-chip
communications and satisfy increasing demand for integrating more diverse functionalities into
smaller device footprints. Over time, as transistor density has increased, traditional interconnects
between chips have limited the speed at which memory, logic, and other chips can communicate.
Many advanced packaging strategies have emerged to enable faster communications, including
placing chips close to each other with a “bridge” (also referred to as a 2.5-dimensional, or 2.5D
approach) or stacking them on top of one another (referred to as a three-dimensional [3D]
strategy) to achieve the shortest distance between interconnections while decreasing the spatial
footprint in the end device.50
This growing segment of the semiconductor supply chain can offer improved device performance
for chip applications (and thus higher value), which may provide more economic feasibility for
reshoring to the United States than traditional, low-value-added packaging operations.51
Companies eligible to apply for funding incentives from the CHIPS Act of 2022 include domestic
advanced packaging facilities. According to a market research firm, advanced packaging
accounted for 40% of the packaging market share in 2020 and is expected to increase to 60% by
2030.52 The United States accounted for nearly a quarter of global advanced packaging
production capacity in 2020, led by Intel and Amkor. Taiwan leads in advanced packaging
capacity, primarily due to capacity at firms ASE Group, TSMC, Chipbond, and ChipMOS.53
Chiplets
Another tool to promote semiconductor innovation is the use of “chiplets.” Electronic devices
such as smartphones and tablets require complex electronic functionalities in small footprints. To
accommodate this requirement, the semiconductor industry shifted to integrating multiple
elements of computing systems (e.g., CPU, GPU, USB controllers, network interfaces) on a
single piece of silicon, often referred to as a system on a chip (SoC). Over time, as more
functionalities were needed and it became costlier and more challenging to produce all features
on the most advanced nodes, the industry has increasingly used separate building blocks called
chiplets. In this process, functions previously performed by a single chip are divided into discrete
functions and fabricated into smaller building blocks, so that only those blocks that need the

highest performance (e.g., the logic component) use the most advanced process nodes, while
other blocks (e.g., input/output power) use mature process nodes.54
The chiplet fabrication process allows unique chiplets to be purchased from different vendors and
packaged together using a “plug-and-play” approach to provide devices with enhanced
functionality (that is, as long as they are designed to communicate with one another). An industry
effort is under way to standardize chiplet design to improve the ability to mix-and-match in the
market and to enable an “open chiplet ecosystem” for end-application developers to optimize
hardware to their specific requirements.55 Promoting the chiplet ecosystem can encourage
innovation when traditional strategies for improving performance may be cost-prohibitive and
create barriers to entry for new companies in the design and fabrication of specialized chips.
China’s semiconductor industry has become increasingly interested in chiplets as a way to work
around current U.S. export controls and address certain capability gaps.56
The Global Nature of Semiconductor Production
The process of producing a finished semiconductor chip involves design and fabrication (i.e.,
manufacturing), as well as assembly, testing, and packaging (ATP). In many cases, these stages
now occur across national borders among a small group of countries that specialize in particular
parts of the supply chain. In some cases, a semiconductor chip can cross international borders 70
times during the production process.57 U.S.-headquartered firms lead globally in chip design and
manufacturing equipment, accounting for the highest global revenues in 2021 for chip design
(46%), as well as the production of semiconductor manufacturing equipment (42%) and design
software/licensing (72%). A small share of global manufacturing capacities is physically located
in the United States for wafer fabrication (11%) and ATP services (5%); the majority of
fabrication and ATP facilities are located in China, Taiwan, South Korea, and Japan.58 In addition,
the semiconductor supply chain relies on U.S. and other global suppliers of materials, chemicals,
gases, and manufacturing equipment.
Semiconductor Industry Business Models
Up until the 1980s, a single company—known as an integrated device manufacturer (IDM)—
typically operated most or all stages of chip production in-house. Although many types of chips
(e.g., memory and analog chips) still operate primarily under the IDM model, advanced logic
chips are now produced mostly by different companies that specialize in particular segments of

54 IEEE Electronics Packaging Society, “Chiplet Definitions,” at https://eps.ieee.org/technology/definitions.html.
55 Several semiconductor and technology firms, including AMD, ARM, Intel, Meta, TSMC, Microsoft, Qualcomm, and
Samsung, have formed an industry consortium to standardize how different chiplets connect to one another so that
customers can mix the products of different companies. Universal Chiplet Interconnect Express, “Leaders in

Semiconductors and the Semiconductor Industry

the supply chain. This specialization allows companies to manage the increasing costs of design
and production associated with new technologies and to benefit from economies of scale. U.S.-
based semiconductor firms first offshored relatively more labor-intensive and lower-value-added
activities such as assembly, test, and packaging in the 1960s, followed by wafer fabrication in the
1980s with the advent of the “fabless/foundry” business model. Contracted facilities for assembly,
test, and packaging services are known collectively as Outsourced Semiconductor Assembly and
Testing (OSAT).59
A fabless company designs chips but does not have its own fabrication facilities; instead it
contracts out the manufacture of its chips to foundries—companies that manufacture chips for
other companies and that generally do not design and manufacture their own chips. As the costs
and complexity of manufacturing advanced semiconductor chips increased over time, the number
of IDMs operating fabs fell. Globally, at the 130 nm process node for nonmemory chips, there
were 22 IDMs operating their own fabs; at the 22 nm mode, there were three IDMs, with the
majority of chip designers becoming fabless and outsourcing manufacturing to foundries.60 The
advent of foundry services has enabled companies that typically relied on off-the-shelf
semiconductor chips (e.g., Apple and Google) to join the semiconductor supply chain and design
chips optimized for their particular applications. Four of the top 10 semiconductor vendors
globally by revenue in 2022 were U.S.-headquartered fabless chip designers (Qualcomm,
Broadcom, AMD, and Apple) that rely largely on foundry and contracted ATP services in Taiwan,
South Korea, and China.61
Design
In the design process, companies conceive new products and specifications to meet customer
needs and use these ideas to create particular logic and circuit designs for manufacture. In 2020,
firms headquartered in the United States led globally in chip design, accounting for about 60% of
global chip sales by companies that design only chips.62 Seven of the top 10 fabless
semiconductor design firms, by revenue, are headquartered in the United States—including the
top three (Broadcom, Qualcomm, and Nvidia); three are headquartered in Taiwan.63
To handle the design of complex circuits with billions of electronic features, chip designers
typically use software called Electronic Design Automation (EDA). EDA providers usually
license certain parts of the fundamental chip design so that designers do not need to recreate it,
thereby saving time and money and allowing designers to focus on innovative changes. These
proprietary designs are also referred to as intellectual property (IP) blocks. Chips used in personal
computers contain dozens of IP blocks for various functions, such as wireless communications
and ethernet connections. In 2021, firms headquartered in the United States accounted for the

largest share of revenues from EDA and IP (72%), followed by Europe (20%).64 The top EDA
software providers include U.S.-headquartered Synopsys and Cadence, as well as Siemens EDA
(U.S.-founded as Mentor Graphics and acquired by Germany-headquartered Siemens in 2017).65
ARM Ltd., a company headquartered in the United Kingdom and owned by Japan’s SoftBank, is
the top provider of IP blocks for the semiconductor industry. The majority of global mobile phone
processors are based on IP designs from ARM Ltd. An open-source technology platform called
RISC-V, first developed at the University of California, Berkeley, in 2010, has been gaining
traction in chip design, providing an accessible alternative to licensing proprietary designs from
companies such as ARM Ltd.
Process Design Kits (PDKs) are used to translate semiconductor designs, made by EDA software,
into manufacturable processes and are specific to the foundry and generation of technology
(process node). Restrictive and expensive PDK licensing by foundries can inhibit small and
medium-sized innovators from realizing the production of their designs. Some companies are
partnering to offer open-source PDK to new designers, to promote innovation and enable them to
produce chips more quickly.66
Fabrication
After the design stage, semiconductor chips are manufactured, or fabricated, in facilities often
referred to as fabs or foundries. In this front-end fabrication process, chips are manufactured on
circular sheets of silicon or, less commonly, other semiconducting materials, called wafers, that
are typically about 8 or 12 inches in diameter. Each circular silicon wafer typically contains
hundreds of different chips (usually tiny rectangles, smaller than the size of a postage stamp). To
produce billions of electronic features on each chip (e.g., transistors), the wafer is covered in a
light-reactive material and exposed to particular sources of light through a mask, similar to a
stencil, containing the blueprints for the circuit pattern; this process is known as
photolithography. After exposure, the unreacted materials and underlying silicon can be etched or
removed to create complex circuit patterns on the wafer. Other manufacturing steps include
adding materials (deposition and implantation), wafer cleaning and smoothing (wet cleaning and
planarization), and thermal treatments (diffusion and annealing). The manufacturing sequence,
which can require more than 1,000 process steps to make advanced logic chip designs, relies on
specialized equipment and materials that are customized and calibrated according to a customer’s
design. In addition, manufacturers conduct a significant amount of research and development to
determine the optimal conditions in which to process the wafer (e.g., optimized temperatures and
chemical mixes) and to produce the highest number of functioning chips (also known as yield).
These recipes and the equipment calibrations are proprietary.
Fabs source equipment and materials from a wide array of global suppliers. It takes more than
four months, on average, to complete production of a chip order. In 2021, fabrication facilities

Japan (16%).67 Fabs can operate as contract manufacturers and produce chips for a variety of
different customers (foundries), produce their own in-house designs (IDMs), or do a combination
of both. In 2021, contract foundries accounted for roughly one-third of global production capacity
for chips, with most foundry capacity located in Taiwan, South Korea, and, to a lesser extent,
China.68
Assembly, Test, and Packaging
After front-end fabrication of the chips, wafers are typically sent to other facilities for back-end
manufacturing activities such as assembly, test, and packaging (collectively known as ATP). In
these steps, chips are cut from the silicon wafer, tested for performance, and packaged to protect
the chip and to allow for its integration into finished electronic devices by attaching electrical
interconnections. Multiple chips with different functions, such as microprocessors, graphics
processors, and memory, are individually packaged and mechanically assembled on a printed
circuit board, connected by wires or pins.69 Contract ATP manufacturers, similar to foundries used
in fabrication, are often referred to as Outsourced Semiconductor Assembly and Test (OSAT)
firms. In 2021, 5% of global ATP capacity was physically located in the United States; the
majority of capacity was located in China (38%), Taiwan (19%), and South Korea (9%).70
Technical advancements in packaging innovation can provide enhanced functionalities for chip
applications, offering higher value and making reshoring to the United States more economically
feasible than traditional, low-value-added packaging operations.71
Advanced Packaging
Materials, Chemicals, and Gases
Semiconductor manufacturing and packaging facilities require a diverse array of raw and
processed materials, chemicals, and gases. Some examples include raw polysilicon and silicon
wafers, chemicals such as hydrogen fluoride and nitric acid, and gases such as helium and neon.
Many suppliers of these components also typically serve other industries with commodity
chemicals and gases. Some specialty components are used primarily in the semiconductor
industry and may present increased risk for supply chain disruptions. For example, the
semiconductor industry accounts for nearly 90% of global demand for neon gas to produce the
lasers needed during the photolithography process (i.e., printing circuit patterns onto silicon
wafers). Ukraine supplies up to 90% of the neon gas used for semiconductor manufacturing in the

United States and an estimated 50% of the global neon gas market. The 2014 and 2022 Russian
invasions of Ukraine have led to neon gas shortages and high price increases.72
Nearly 90% of the semiconductor industry’s silicon wafers are supplied by five firms,
headquartered in Japan (SUMCO and Shin-Etsu, 49%), Taiwan (GlobalWafers, 15%), Germany
(Siltronic, 11%), and South Korea (SK Siltron, 11%). A summary of the Department of
Commerce’s Request for Information on bottlenecks in the semiconductor supply chain
contributing to chip shortages in 2021 cited limited availability of silicon wafer production
capacity, with no apparent short-term solutions.73 SUMCO, a leading global supplier, indicated in
2022 that all production capacity for the most common size of silicon wafer (300 mm in
diameter) was sold out through 2026.74 Because demand for wafers is likely to increase with
many announced global investments into increasing chip manufacturing capacities, supply
constraints for silicon wafers may persist in the coming years. However, new wafer
manufacturing capacity is also planned. In December 2022, GlobalWafers began construction on
a $5 billion wafer production factory expected to begin production in 2024.
Demand for semiconductor materials is closely correlated with the locations for semiconductor
manufacturing; facilities in the United States accounted for 10% of semiconductor materials
demand in 2021. The locations with the highest demand for semiconductor materials were China
(19%), Taiwan (19%), South Korea (17%), and Japan (16%); these are also the locations with the
highest wafer fabrication capacities.75
Equipment
Semiconductor production requires complex equipment, including photolithography machines to
print circuit patterns; etch and clean machines to remove materials; deposition and implantation
machines to add new materials; diffusion machines for thermal treatments; process control
equipment to ensure quality; wafer handling to transport wafers; and planarization machines to
smooth out wafer surfaces. U.S.-headquartered firms lead in the producing of nearly all types of
semiconductor manufacturing equipment except photolithography and wafer handling,
accounting for the highest revenues in 2021 (42%), followed by Japan (27%) and Europe
(21%).76 Leading global equipment suppliers headquartered in the United States include Applied
Materials, Lam Research, and KLA. Chinese and Japanese companies lead in equipment used for

wafer handling as well as packaging, assembly, and testing of semiconductors. Photolithography
equipment is produced primarily in Europe (Netherlands) and Japan.77
Since the introduction of China’s state-led semiconductor industrial policies in 2014, U.S. exports
of semiconductor equipment to China have increased nearly fivefold (by over 350%).78 China is
almost completely dependent on imported equipment, although new industrial policies seek to fill
this gap by funding PRC semiconductor software tools and equipment firms.79 In October 2022,
to slow the indigenous ability of China to develop and mass-produce advanced chips, BIS enacted
new restrictions requiring licenses for the exports of certain semiconductor equipment and
services by U.S. persons used in the production of advanced logic and memory chips in PRC
facilities. According to news reports, in February 2023 the United States reached an agreement
with the Netherlands and Japan to also restrict certain advanced semiconductor equipment sales
to China. China’s new outlays of subsidies, estimated at $143 billion over five years, are focused
on covering the costs of equipment, including imports and the development of domestic firms.80
PRC foundries such as SMIC, Huahong Group, Nexchip, and IDM Silan Microelectronics have
stocked up on semiconductor equipment, including equipment from the second-hand global
market that the U.S. government had restricted from being directly exported to PRC firms in
China (e.g., Huawei).81
Photolithography Equipment
Photolithography machines are an essential component of the semiconductor fabrication process.
Photolithography equipment is used to pattern bil ions of electronic features on a silicon wafer by using different
types of light passing through a mask (similar to a stencil) onto the underlying wafer, which is covered in light-
sensitive materials. As electronic features have become smaller with more advanced process nodes, smaller
wavelengths of light are required. For the most advanced process nodes (e.g., 3 nm and 5 nm), extreme ultraviolet
(EUV) light is primarily used to pattern circuits onto the wafer; manufacturing processes for more mature process
nodes (typically above 7 nm) use deep ultraviolet (DUV) light in the patterning process. EUV photolithography
equipment has taken decades of research and development to produce and is made by a single company in the
Netherlands, ASML. The remaining photolithography equipment market is accounted for by ASML and firms
headquartered in Japan.

Semiconductors and the Semiconductor Industry

Challenges for Transitioning from Research and Development to
Production
Small and medium-sized semiconductor companies face challenges in securing manufacturing
capacity due to the prioritization of higher-volume orders from larger businesses, according to a
Commerce Department survey. In addition, startups and other entities that account for relatively
small portions of semiconductor demand (e.g., national laboratories, universities, and the
Department of Defense, which create semiconductor designs using innovative materials or
processes) may not be able to manufacture their designs in foundries, which typically use
standard processes. This is sometimes referred to as the “lab-to-fab gap,” and it affects the ability
of enterprises accounting for a small share of semiconductor demand to prototype and scale the
manufacturing of their designs. To address this gap, an open-access foundry coordinated by the
National Semiconductor Technology Center (created pursuant to provisions in the CHIPS Act of
2022) can receive co-investment from qualified participants to increase the ability of domestic
entities to prototype innovative designs.82
According to the Commerce Department, a number of challenges are associated with
commercializing semiconductor research and development and securing production capacity for
chip designs. At the same time, these challenges may provide the United States with an
opportunity to encourage innovation and advance national security efforts. Some challenges
include the following:
 At the design phase, chips need to be manufactured in small quantities to debug
and validate the design, yet foundries and advanced packaging facilities are not
structured for small runs. The prototyping process requires improved access to
shared infrastructure, such as multiproject wafer runs and design libraries.
 The costs of prototyping and testing designs has increased worldwide. Venture
capital and other investors are reluctant to invest in projects at the early stage
given the high cost, the long time required to validate that a new technology
works as designed, and the resulting risk.
 The industry lacks agreement on roadmaps to guide the concurrent development
of tools, materials, and manufacturing processes.
 The industry faces difficulty in attracting and retaining domestic and
international research scientists in the highly competitive global market for
technology talent.
 For innovations beyond design, such as new devices and materials, high
development costs and long payoff times pose additional risks.83
These challenges are especially daunting to smaller firms and startups, potentially deterring
innovation.

Semiconductors and the Semiconductor Industry

U.S. Semiconductor Industry
According to the Semiconductor Industry Association (SIA), the United States “has been the
long-standing global leader in semiconductors, with a 45% to 50% share of worldwide revenues
in the last 30 years.”84 About 800 semiconductor and related device manufacturing firms were
located in the United States in 2020.85 While the U.S. semiconductor industry plays a leading role
in many parts of the semiconductor supply chain (e.g., semiconductor design and equipment
manufacturing), domestic semiconductor manufacturing capacities have been in decline for
decades. In addition, U.S. industry has lost its leadership position over time in assembly,
packaging, and test capabilities, as those functions have been offshored, primarily to Southeast
Asia and China.86 U.S. industry has also lost its leadership in memory chips through decades of
state support in Japan, South Korea, and Taiwan.87 U.S. industry currently faces growing
competition from China in many parts of the supply chain, including materials, gases, and power
chips, where PRC industrial policies are focused. PRC state policies are also seeking to close
gaps where China depends on U.S. and other foreign firms, such as EDA software design tools
and semiconductor manufacturing equipment.88
Some U.S.-headquartered semiconductor firms that design and manufacture in the United States
have built fabrication facilities overseas. Similarly, U.S. design firms that do not own or operate
their own fabrication facilities contract with foreign firms located overseas to manufacture their
designs. Much of this overseas contract fabrication capacity is in Asia, primarily in Taiwan, South
Korea, and China.
Six semiconductor companies currently operate 20 fabrication facilities, or fabs, in the United
States. However, with the movement of many U.S. firms toward a fabless model (companies that
design, but do not manufacture, semiconductors) and the outsourcing of manufacturing to
companies located offshore, the share of semiconductor fabrication capacity located in the United
States has experienced a long-term decline—from around 40% in 1990 to approximately 12% in
2020, according to SIA,89 and from 26.1% in 1995 to 12.6% in 2015, according to trade

association SEMI.90 This fabless trend has contributed to a concentration of global chip
production among a handful of firms operating fabs in East Asia. Prior to enactment of the CHIPS
Act of 2022, the U.S. share was projected to fall further, as planned new foreign fabs are expected
to open in the next few years, particularly in East Asia.
The globalization of the semiconductor industry has involved a process of offshoring key aspects
of the U.S. supply chain, including production, allowing foreign firms and markets to gain key
market shares and competencies. U.S. industry is now increasingly challenged by China’s
ambitious state-led efforts to simultaneously build out leadership capabilities in all parts of the
semiconductor supply chain. Although China is a latecomer to the sector and lags behind
technologically, its capabilities are advancing rapidly, with strong state support and the ability to
leverage access to China’s market to require or otherwise incentivize foreign technology transfer.
China has made technological strides through
 state-tied acquisitions of, and joint ventures with, foreign semiconductor firms
(including firms such as AMD, Intel, and ARM, which own core IP for
semiconductor chip architecture);
 technology transfer and licensing;
 an increasingly active use of open-source technology platforms for chip design
and testing (e.g., RISC-V);
 talent development and research and development operations in the United
States;
 efforts to attract foreign industry talent to China (particularly from Taiwan);
 IP theft; and
 capital investments and support from U.S. and foreign industry to build out
China’s semiconductor suppliers for key customers, such as Apple.91
In late 2018, Taiwan-headquartered Hon Hai Precision, or Foxconn, the key contract
manufacturer for Apple, signed a deal with the PRC’s Nanjing city government to build a new
$282 million chip manufacturing equipment factory. Around the same time, Foxconn signed a
deal with the Jinan government to jointly create a $523 million industrial fund to finance
semiconductor design firms. Foxconn is also reportedly building a semiconductor packaging and
testing plant in Qingdao for AI and 5G chips. The facility is co-financed with the PRC’s state-
backed Rongkong Group.92 The firm has co-invested with the PRC in a chip fab for IoT, AI, and
5G chips, leveraging Sharp’s semiconductor expertise—a company Foxconn acquired in 2016.93

These developments in China continue to heighten concerns about the competitive position of the
U.S. semiconductor industry.
Planned Fabs and Supplier Facilities Locations
Sixty-one semiconductor fabrication facilities have a high probability of beginning construction
from 2021 through 2023, with the most facilities located in Taiwan (15), China (14), United
States (10), Europe (9), and Japan (7).94 Of these 61 fabs, 14 are anticipated to be equipped to
produce advanced nodes (below 7 nm).
Semiconductor manufacturing firms headquartered in the United States operate more than half of
their fabrication capacity outside of the United States, primarily in Taiwan, Japan, Singapore, and
Europe.95 In addition, while the companies capable of producing the most advanced logic chips
currently in production (3 nm node) are building additional fabs in the United States, they
reportedly produce their most advanced chips in the location of their headquarters (i.e., Taiwan
for TSMC and South Korea for Samsung Foundries).
Between 2020 and 2022, U.S.- and foreign-headquartered firms announced over $200 billion in
private investments to expand domestic manufacturing capacities for semiconductor fabrication,
equipment, and materials across 16 states, with the largest investments announced for logic and
memory chip fabrication facilities Arizona, Texas, Idaho, Ohio, and New York.96 Figure 3
illustrates industrial plans to expand U.S.-based semiconductor manufacturing (see Appendix A

Lead-Time for Domestic Production
Globally, fab construction on a new site (also referred to as a greenfield site) typically takes
between two to four years before it is fully operational. Between 2010 and 2020, fabs constructed
in the United States took two-and-a-half years on average from the start of construction to begin
production. In contrast, during the same period, fabs built in the PRC and Taiwan required about
1.8 years to complete construction.97 According to Intel executives, when discussing plans for
fabs in the United States and Germany, “best-in-class” semiconductor fabs take three to five years
to build after the land, construction team, and the vision for the facility are in place.98
Preconstruction activities include design and permit approvals, followed by site development,

installation of various utility and process systems (e.g., clean room and delivery systems for
chemical and gases), and installation of equipment used to process wafers.
Some industry experts/analysts have pointed out that extensive permitting requirements can
increase the time associated with fab construction. For example, obtaining preconstruction and
operating permits required under the Federal Clean Air Act can take 12 to 18 months.99 In
addition, domestic fab construction projects that receive financial incentives under the CHIPS Act
of 2022 may require review under the National Environmental Policy Act (NEPA), which applies
to construction projects considered as major federal actions. Potential strategies to reduce the time
associated with permitting include expedited reviews and resolution of redundant federal and
state permit requirements. Other federal agencies involved in regulating environmental health and
safety aspects of fab construction and operation include the U.S. Army Corps of Engineers and
the U.S. Department of the Interior.
Facility Site Selection Considerations
When deciding where to locate or expand semiconductor fabrication facilities, manufacturers may
consider a variety of factors:
 capital costs;
 labor availability and costs;
 regulatory environment;
 land costs;
 water, waste treatment, and electricity costs;
 energy reliability;
 transportation infrastructure;
 proximity to customers;
 political stability;
 trade barriers (e.g., tariffs and technology transfer or localization requirements);
 national security requirements (e.g., export controls, trusted foundry
requirements); and
 financial incentives and subsidies offered by national, regional, and local
governments.100
Leading-edge logic and memory chips require some of the highest fab construction costs of any
type or generation of chip. The costs to construct and equip a fab producing leading-edge logic
chips was around $5 billion in 2020 (5 nm node), compared with $3 billion in 2016 (7 nm node).

Semiconductors and the Semiconductor Industry

For comparison, the cost of a leading-edge fab in 1992 was approximately $500 million.101
Because memory chips are a commoditized semiconductor product differentiated by the lowest
prices, producers of memory chips typically need to construct the largest chip fabrication
facilities (producing over 100,000 wafers a month) to benefit from economies of scale.
Accordingly, a new memory chip factory could incur costs of more than $15 billion to
construct.102 By some estimates, the cost of equipping a fab can be about half of the total cost.
Intel reports that equipment accounts for $92.7 billion (more than half) of its total of $174.3
billion in property, plant, and equipment.103
The cost of building and operating a fab (total cost of ownership, or TCO) is higher in the United
States than it is in several Asian countries. The TCO for a fab located in the United States is
approximately 25% to 30% higher than the equivalent fab located in Taiwan or Singapore, and
50% higher than a fab located in China, to a large extent due to financial support that
governments offer in these markets.104 Many countries provide incentives for the construction and
operation of fabs and support the training of fab workers, which lowers the TCO for companies in
those locations. An analysis by the SIA and Boston Consulting Group found that “government
incentives typically reduce up-front capital expenditure on land, construction, and equipment, but
they can also extend to recurrent operating expenses such as labor costs,” and estimated that
“government incentives can offset between 15% and 40% of the gross TCO (before incentives) of
a new fab, depending on the country.”105 Further, the analysis concluded that government
incentives constitute 40%-70% of the cost advantage other countries have over the United States.
Historically, the assembly, test, and packaging (ATP) sectors of the semiconductor industry have
been less profitable than chip fabrication and have required more labor for less value-added
activities. Accordingly, ATP functions were the first stage of semiconductor production to be
outsourced and offshored to Asia beginning in the early 1970s. In 2021, ATP facilities located in
the United States accounted for 5% of global ATP capacity. Facilities located in Asia accounted
for more than 70% of ATP capacity, led by China and Taiwan.106
The United States, however, has a large share of advanced packaging capacity—nearly a quarter
in 2020, and it may become a more attractive location as automation reduces the importance of

comparison, the cost of a leading-edge fab in 1992 was approximately $500 million (see National Academies Press,
Dispelling the Manufacturing Myth: American Factories Can Compete in the Global, 1992). In 2022, the cost (in
inflation-adjusted dollars) was approximately five times higher.

Considerations for Congress
The growth in federal attention and support to expand domestic semiconductor manufacturing
capabilities and competitiveness, including appropriations in the CHIPS Act of 2022 (P.L. 117-
167), raises a number of implementation and oversight issues for Congress. As global demand for
semiconductor chips is expected to increase substantially over the next decade, from a roughly
$600 billion market in 2022 to $1 trillion by 2030, the resiliency of the domestic semiconductor
industry will likely remain an area of congressional interest in the future.110

Semiconductors and the Semiconductor Industry

In this context, potential issues for Congress may include the following:
 How effective have allocations of federal financial incentives available through
the CHIPS Act for domestic semiconductor manufacturing facilities been in
promoting economically viable and competitive semiconductor technologies?
 Should the United States increase coordination with international partners to
strengthen supply chain resilience by, for example, aligning investment priorities
and developing mechanisms to monitor supply disruptions?
 What other tools, if any, should the federal government utilize to increase supply
chain security for semiconductors, such as stockpiling critical materials,
establishing programs for supply chain risk assessments and transparency, and
monitoring demand from critical manufacturing industries?
 Are different federal strategies required for promoting technological leadership in
leading-edge semiconductor nodes that require more capital investments versus
strategies for ensuring supply chain security across many technology nodes,
including mature chips?
 How successfully have federal research and development programs and
manufacturing incentives enabled broader access to prototyping and
manufacturing facilities for start-ups, universities, and small businesses?
