China Semiconductor Localization 2025: Self-Sufficiency Drive
China's drive for semiconductor self-sufficiency has become one of the most consequential technology initiatives globally. With US export restrictions limiting access to advanced chips and manufacturing equipment, China invested over 500 billion RMB in domestic semiconductor production in 2025, achieving approximately 35% self-sufficiency in chip production by value. SMIC, China's leading foundry, achieved breakthroughs in 7nm and 5nm process technology despite equipment restrictions.
TL;DR
China produced chips worth 1.2 trillion RMB domestically in 2025, representing approximately 35% self-sufficiency. SMIC began volume production at 7nm and achieved initial 5nm yields. Huawei's HiSilicon designed the Kirin 9020 chip fabricated by SMIC. Domestic equipment makers captured 25% of the Chinese semiconductor equipment market, up from 15% in 2023.
Key Insights
Domestic Chip Production
China's domestic semiconductor production reached 1.2 trillion RMB in value, growing 20% year-over-year. While most domestic production remains at mature nodes (28nm and above), progress at advanced nodes has accelerated significantly.
SMIC Advanced Nodes
SMIC achieved volume production at 7nm using DUV lithography with multi-patterning techniques, and reported initial yields at 5nm. This represents a remarkable engineering feat given the lack of EUV lithography equipment due to export restrictions.
Semiconductor Investment
China invested over 500 billion RMB in semiconductor manufacturing capacity in 2025, including 12 new fab construction projects and expansion of existing facilities. Government funds, private equity, and state-owned enterprises all contributed.
Equipment Localization
Domestic semiconductor equipment makers captured 25% of the Chinese equipment market, up from 15% in 2023. Companies like Naura, AMEC, and NAURA Technology made progress in etching, deposition, and inspection equipment.

Frequently Asked Questions
China's path to semiconductor self-sufficiency faces significant challenges but has made remarkable progress. The realistic timeline and targets are: near-term (2025-2027) focus on mature nodes (28nm and above) where China is rapidly building capacity, targeting 50% self-sufficiency for chips used in consumer electronics, automotive, and industrial applications; medium-term (2027-2030) push to advance nodes (14nm, 7nm, potentially 5nm) using multi-patterning DUV techniques and potentially domestic EUV alternatives, targeting 40% overall self-sufficiency by value; long-term (2030-2035) potential achievement of competitive leading-edge manufacturing if domestic equipment development succeeds. Key challenges that remain: EUV lithography equipment (only ASML produces EUV machines, and China cannot purchase them); advanced photoresist chemicals (Japan dominates with over 80% market share); EDA tools (US companies Synopsys, Cadence, and Siemens EDA dominate); and talent shortage (China trains fewer advanced semiconductor engineers per capita than the US, Japan, or South Korea). Despite these challenges, China's massive investment and government support mean progress will continue. The realistic expectation is achieving self-sufficiency for most applications at mature nodes within 5-7 years, while leading-edge nodes will likely remain behind global leaders for 10+ years.
