China has begun domestic production of immersion DUV lithography machines, a chipmaking tool long dominated by ASML, with initial output of five units expected this year and 20 in 2027, though the domestic systems lag in performance and reliability compared to ASML machines.
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
ASML's monopoly on DUV tools is cracking under export controls, and China's domestic alternative—however inferior today—is now a proven buyer for component makers who can work into their supply chain. Your optics, power systems, or precision mechanics now have a second customer at scale, one immune to Dutch and US export restrictions.
