China has begun mass production of domestic deep ultraviolet (DUV) lithography equipment, breaking a U.S. export restriction and enabling local foundries to produce 28nm and below semiconductors without foreign equipment. The state-owned Shanghai firm plans to produce 5 units this year and 20 next year, supplying SMIC, Huahong, and CXMT.
This Wire brief sits within Fusion42's coverage of Semiconductors, and 22 sources have reported it between 27 Jul 2026 and 6 Aug 2026.
◆ ◆ The Wire takeaway
U.S. export bans just handed China a working DUV supply chain. If you make semiconductor test equipment, packaging substrates, or materials for 28nm-class production, your customer base has shifted from needing Western lithography to needing everything else—and China's foundries will now buy domestically first.
