Xin Lang Cai Jing·2025-11-11 06:26Core Insights - The article emphasizes the critical role of DUV lithography in semiconductor manufacturing, highlighting that it accounts for 80% of microelectronic chips produced globally, with 90% of the production layers still relying on DUV technology despite the emergence of EUV [1][3][11]. DUV Technology - DUV lithography machines operate at wavelengths from 365 nm to 193 nm, covering mainstream processes from 0.35 microns to 14 nm, making them both effective and cost-efficient [3][11]. - The immersion technology introduced by TSMC in 2002 significantly improved DUV's resolution to below 40 nm, doubling efficiency and enhancing yield rates [6][7]. - DUV's maturity and widespread deployment, with thousands of machines in operation, cater to various sectors, including consumer electronics and industrial control [11][13]. Market Dynamics - The demand for mature nodes (28 nm and above) is substantial, with production numbers starting from trillions of chips, driven by industries such as automotive and home appliances [9][24]. - DUV's cost-effectiveness, with machines priced at about half that of EUV, and quicker installation times make it accessible for smaller manufacturers [13][15]. Supply Chain and Geopolitical Factors - The U.S. restrictions on EUV technology have led Chinese companies to pivot towards DUV, resulting in a surge in imports, with China importing approximately 100 DUV machines worth €2.1 billion in 2022 [15][17]. - In 2023, Chinese imports of DUV machines reached €5.28 billion, nearly double the previous year's total, indicating a strong demand amidst geopolitical tensions [17][19]. Future Projections - By 2025, China's production capacity for mature chips (28 nm and above) is expected to account for 33% of the global market, up from 27% in 2023, with major contributions from companies like SMIC [22][24]. - The automotive sector is projected to see significant growth, with 70% of the demand for electric vehicles relying on 28 nm chips, further solidifying DUV's importance in the semiconductor landscape [24][26].
