SMIC vs TSMC vs Samsung
Semiconductor Manufacturing International Corporation (SMIC, 中芯国际), founded in 2000 in Shanghai, is China's largest and most advanced semiconductor foundry. While TSMC of Taiwan and Samsung of South Korea dominate global chip manufacturing at the leading edge, SMIC plays a critical strategic role as China's primary path to semiconductor self-sufficiency. Subject to US export controls that restrict access to EUV lithography equipment, SMIC has pushed the limits of DUV (Deep Ultraviolet) lithography to produce 7nm-class chips used in Huawei's Kirin 9000s processor. With over $7 billion in annual revenue and backing from China's national semiconductor fund, SMIC represents both the ambition and constraints of China's chip industry.
TL;DR
SMIC is China's largest chip foundry with $7B+ revenue (2024). Mass-producing 7nm using DUV (no EUV access). Subject to US sanctions limiting advanced equipment access. Key supplier for Huawei's Kirin chips.
Key Insights
China's #1 Foundry
SMIC is China's largest semiconductor foundry by revenue, operating 14nm and 7nm-class production lines in Shanghai, Beijing, Tianjin, and Shenzhen.
$7B+ Revenue
SMIC generated over $7 billion in revenue in 2024, making it the world's fifth-largest foundry behind TSMC, Samsung, GlobalFoundries, and UMC.
7nm DUV Process
SMIC achieved 7nm-class production using multi-patterning DUV lithography, bypassing the EUV ban. Used in Huawei's Kirin 9000s for the Mate 60 Pro.
US Sanctions Impact
US export controls since 2019 and expanded in 2022-2023 restrict SMIC's access to EUV lithography equipment and advanced chips, limiting progress below 5nm.
100K+ Wafers/Month
SMIC operates over 100,000 wafer starts per month across mature nodes (28nm+) with approximately 8% global foundry market share.

Frequently Asked Questions
Currently, SMIC cannot mass-produce 5nm or 3nm chips. Without EUV lithography equipment (banned by US export controls), SMIC would need to use extremely complex multi-patterning DUV that is commercially unviable. Industry analysts estimate SMIC's current practical limit is 7nm using DUV, with potential 5nm at very low yields.
SMIC uses a technique called SAQP (Self-Aligned Quadruple Patterning) with DUV lithography to achieve 7nm feature sizes. This requires multiple exposures of the same wafer layer, making production slower and more expensive than EUV-based 7nm from TSMC. Yield rates are estimated at 30-50% versus 90%+ for TSMC's EUV 7nm.
SMIC has narrowed the gap from approximately 5 generations to 2-3 generations over the past decade. However, without EUV access, the gap may widen again as TSMC pushes to 2nm and below. Most analysts believe SMIC cannot fully close the gap while US export controls remain in effect.
SMIC is critical to China's semiconductor self-sufficiency strategy. Without domestic foundry capability, China relies entirely on imports ($350B+ annually) for advanced chips. SMIC is the only Chinese company capable of producing advanced logic chips at scale, making it a national strategic priority with significant government funding.
SMIC manufactures a wide range of chips including Huawei's Kirin 9000s smartphone processor, automotive chips, IoT chips, display driver ICs, fingerprint sensors, and power management ICs. The company is strongest in mature nodes (28nm and above) which account for approximately 80% of its revenue.
