China Chip Industry: SMIC, Huawei HiSilicon, and the Push for Semiconductor Self-Sufficiency
China's semiconductor industry is at the center of the U.S.-China technology rivalry. Despite comprehensive U.S. export controls targeting advanced chip manufacturing equipment, China has made significant strides in building domestic semiconductor capabilities. SMIC has achieved 7nm-class production, Huawei's HiSilicon continues designing advanced chips despite sanctions, and the domestic equipment and materials supply chain is rapidly maturing. This guide examines the current state of China's chip industry, key players, and the path toward greater self-sufficiency.
TL;DR
China's chip industry is advancing rapidly despite U.S. sanctions. SMIC produces 7nm-class chips, Huawei continues Kirin chip design, and China invests $150B+ to build a domestic semiconductor supply chain.
Key Insights
SMIC (Semiconductor Mfg)
SMIC, China's largest contract chipmaker, has achieved 7nm-class production using deep ultraviolet (DUV) lithography through multi-patterning techniques. While yield rates are lower than TSMC, the achievement demonstrates China's ability to produce advanced chips without EUV equipment denied by U.S. sanctions.
Huawei HiSilicon
Huawei's chip design arm HiSilicon continues producing advanced Kirin processors despite being cut off from TSMC manufacturing. The Kirin 9010, used in the Mate 60/70 series, is manufactured by SMIC at approximately 7nm. Huawei has also developed the Ascend AI chip series as an NVIDIA alternative.
Government Investment
China's National Integrated Circuit Industry Investment Fund (Big Fund) has raised over 150 billion USD across three phases. Combined with provincial and local subsidies, total semiconductor investment exceeds 300 billion USD, making it the largest state-backed chip program in history.
Memory Chips
Yangtze Memory Technologies (YMTC) produces 232-layer 3D NAND flash, approaching Samsung and Micron technology. CXMT (ChangXin Memory) manufactures DRAM at 17nm. Both face U.S. equipment restrictions but continue technology development.
Equipment Gap
China's biggest weakness is chip manufacturing equipment. Domestic lithography machines from Naura and SMEE reach only 28nm resolution vs ASML's EUV at 3nm. China imports 85 percent+ of its semiconductor equipment, primarily from Japan, Netherlands, and the U.S.
Talent
China trains over 500,000 semiconductor engineers and technicians annually across 100+ university programs. Overseas returnees bring critical expertise. However, experienced senior engineers and researchers remain scarce compared to Taiwan and South Korea.

Frequently Asked Questions
China has demonstrated the ability to produce 7nm-class chips using domestic DUV lithography through multi-patterning techniques, as shown by SMIC's production of Huawei's Kirin chips. However, achieving 5nm and below without EUV lithography remains extremely challenging. China's current advanced chips have lower yields and higher costs than TSMC equivalents.
SMIC (Semiconductor Manufacturing International Corporation) is China's largest contract chip manufacturer, analogous to TSMC for Taiwan. Founded in 2000, SMIC produces chips for fabless companies including Huawei HiSilicon. Its ability to manufacture at 7nm-class nodes despite U.S. equipment restrictions makes it central to China's semiconductor self-sufficiency goals.
U.S. export controls (October 2022 and updates) restrict China's access to advanced chip manufacturing equipment (particularly ASML EUV lithography), high-end AI chips (NVIDIA A100/H100), and restrict U.S. persons from working at Chinese chip facilities. These sanctions have slowed but not stopped China's chip advancement.
Full self-sufficiency is unlikely before 2035 for the most advanced nodes. China can achieve significant self-sufficiency for mature nodes (28nm and above) within 5 years, covering the majority of automotive, industrial, and IoT chip demand. Advanced nodes (sub-7nm) for smartphones and AI remain heavily dependent on imported or smuggled equipment.
China is the world's largest chip consumer (importing over 400 billion USD annually) but produces only about 15-20 percent of its needs domestically. SMIC ranks 5th globally among foundries by revenue. China leads in mature node capacity expansion but trails TSMC and Samsung by 5-10 years at the leading edge.
