For most of the past four decades, the global semiconductor industry operated on a clear geographic logic: chips were designed in the United States, fabricated in Taiwan and South Korea, and assembled throughout Southeast Asia. China was a consumer and assembler, not a maker. That structure is now under sustained pressure. At the center of China’s effort to change it is Semiconductor Manufacturing International Corporation, better known as SMIC.
Understanding SMIC is essential for any executive involved in technology hardware, supply chain strategy, or US-China trade. The company is not merely a Chinese business story. It is a strategic flashpoint reshaping trade policy, supply chain investment decisions, and the long-term competitive landscape of the global chip industry.
SMIC: From Startup to National Champion
SMIC was founded in Shanghai in 2000 by Richard Chang, a Texas Instruments veteran. Chang’s ambition was straightforward: create a world-class contract chip foundry in China, modeled on TSMC’s playbook, to serve a domestic electronics industry consuming semiconductors at a pace no Chinese company could supply.
The company grew steadily through the 2000s, listing on the Hong Kong Stock Exchange and initially the New York Stock Exchange. By the early 2010s, SMIC was producing chips at 28-nanometer process nodes, commercially viable for automotive controllers, industrial electronics, and consumer devices. Revenue reached approximately RMB 32.7 billion (around $4.5 billion) in 2022, making it the fourth-largest pure-play foundry in the world by revenue, behind TSMC, Samsung Foundry, and GlobalFoundries.
What transformed the company’s trajectory was not organic growth but the geopolitical environment surrounding it. US sanctions against Huawei, which expanded dramatically in 2020, demonstrated that any Chinese technology company relying on foreign-controlled chip supply was strategically exposed. SMIC became overnight both the most important company in China’s semiconductor ecosystem and one of the most scrutinized by US regulators.
The US Export Control Impact
In December 2020, the US Department of Commerce added SMIC to its Entity List, restricting American companies from selling certain equipment and technology to the firm without a license. The restrictions specifically targeted tools that could advance SMIC beyond the 10-nanometer node, the point at which chips become useful for advanced AI processors, 5G base stations, and military applications.
Most critically, SMIC was cut off from extreme ultraviolet (EUV) lithography machines manufactured by ASML, the Dutch company holding a near-monopoly on EUV technology. Without EUV, producing chips below 7 nanometers using conventional methods requires extraordinary workarounds. Restrictions also complicated access to US-origin chip design software and specialized chemicals.
For a full picture of how these controls function and their implications for Western importers, see our analysis of China’s Export Controls: What Western Importers Must Understand. The dynamic cuts both ways: China is simultaneously subject to US chip export controls and has deployed its own export controls on rare earth minerals, covered in depth in our guide on China’s Rare Earth Dominance.
The 7nm Breakthrough: What It Signals
In August 2023, Huawei released the Mate 60 Pro smartphone, which was found to contain a 7-nanometer chip, the Kirin 9000s, manufactured by SMIC. The revelation stunned the industry. Most analysts had assumed that without EUV and with Entity List restrictions in place, SMIC could not produce at 7nm.
The technical explanation: SMIC achieved 7nm production using an older deep ultraviolet (DUV) lithography process, running multiple exposure passes to achieve the required resolution. This multi-patterning approach is significantly more expensive and lower-yield than EUV-based production, reportedly two to three times the cost per wafer, but it works. SMIC had engineered around the restrictions using equipment it already possessed.
The Kirin 9000s chip is not competitive with leading-edge processors from TSMC or Samsung on their 3nm and 4nm nodes. Performance benchmarks put it roughly on par with chips from 2019 to 2020. But the strategic significance is substantial: China demonstrated that semiconductor self-sufficiency at a commercially relevant node is achievable, even under sanctions. The US responded with additional restrictions in 2023 and 2024, expanding DUV equipment controls to the Netherlands and Japan, but the momentum of China’s domestic program has not been reversed.
The Scale of State Investment
SMIC does not operate as an isolated company. It is the production anchor of a state-backed ecosystem. The China Integrated Circuit Industry Investment Fund, informally called the “Big Fund,” has committed over 300 billion RMB (approximately $41 billion) across two fundraising rounds to subsidize the domestic chip industry. SMIC has been a primary beneficiary.
Beyond SMIC, a parallel ecosystem is forming. Yangtze Memory Technologies Corporation (YMTC) is expanding NAND flash memory production. ChangXin Memory Technologies (CXMT) is targeting DRAM. The domestic equipment industry, led by NAURA Technology Group, Advanced Micro-Fabrication Equipment (AMEC), and Kingsemi, is growing to substitute for restricted foreign tools. For a deeper look at how government subsidy programs are shaping competitive dynamics, see our post on China’s Semiconductor Subsidy Programs and Their Trade Implications.
What This Means for Businesses
For companies buying chips: Restrictions have not materially disrupted supply of chips used in most consumer electronics, automotive, and industrial applications. SMIC’s capacity is largely focused on mature nodes (28nm and above), which represent the bulk of global chip demand by volume. Near-term supply disruptions remain a risk rather than a current reality for most buyers.
For technology companies with China operations: The Huawei case demonstrated that reliance on a single-source chip supply subject to geopolitical disruption is a structural vulnerability. Companies designing products with advanced chips need to assess their exposure and build supplier diversification into their roadmaps. The Semiconductor Industry Association (SIA) estimates that US semiconductor companies derive approximately 27 percent of their global revenue from Chinese customers, adding significant complexity to any policy calculation.
For Western semiconductor companies competing in China: China is simultaneously a massive customer and an emerging competitor. As domestic capacity scales, particularly at mature nodes, existing revenue streams will face substitution pressure. The Huawei case illustrates the broader pattern: sanctions accelerated domestic Chinese chip development rather than permanently blocking it. See our analysis of Huawei: The Rise, The Sanctions, and What It Means for Global Tech Supply Chains.
Official Perspectives: Beijing and Washington
The Chinese government’s official position frames semiconductor self-reliance as a matter of economic security and technological sovereignty. The Ministry of Industry and Information Technology (MIIT) has published detailed roadmaps emphasizing civilian industrial applications and supply chain resilience, available at the official MIIT website.
The US government’s position, articulated through the Bureau of Industry and Security (BIS), frames export controls as measures to prevent advanced chip technology from being used for military modernization. BIS publishes regular guidance on the Entity List and control parameters at bis.gov, the authoritative resource for compliance teams navigating this complex regulatory landscape. Both positions contain legitimate elements; the challenge for businesses is navigating between them.
The Node Gap and What to Watch
The gap between SMIC’s best current capability and TSMC’s leading edge has narrowed considerably. In 2020, TSMC was producing at 5nm while SMIC was at 14nm. By 2026, TSMC has moved to 2nm volume production while SMIC has demonstrated 5nm capability in limited quantities, with volume at 7nm. The gap is roughly three to four years, depending on how node comparisons are made.
Closing that gap entirely is constrained by the physics of EUV, which SMIC still cannot obtain, and the ecosystem depth TSMC has built over 35 years. But for China’s strategic priorities, including sovereign AI data centers, 5G infrastructure, and defense electronics, SMIC’s current trajectory is sufficient to reduce, though not eliminate, dependence on foreign foundries.
The Bottom Line
China’s semiconductor push is a multi-decade industrial strategy with state-level resources behind it. SMIC is the most visible production node of that strategy. For Western executives, three practical takeaways stand out.
First, supply chain diversification away from Taiwan-centric chip sourcing is sound risk management. SMIC’s growing capacity at mature nodes adds a meaningful alternative for non-leading-edge applications, compliance considerations aside.
Second, technology decoupling is real but selective. The most aggressive restrictions target a narrow band of advanced chips. The vast majority of semiconductor applications remain accessible through normal commercial channels, and bilateral chip trade exceeds $50 billion annually.
Third, compliance frameworks must evolve continuously. BIS rules governing chip exports and re-exports to China have changed multiple times in four years. Businesses with meaningful exposure to either market can no longer treat trade compliance as a back-office function. It is a front-line strategic capability.
