China has begun production of domestic immersion deep ultraviolet (DUV) chipmaking tools, marking a major step towards reducing reliance on Western semiconductor equipment suppliers like ASML. The move signals Beijing's accelerating effort to build a self-sufficient chip manufacturing ecosystem despite international export controls.
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 stranglehold on DUV supply just cracked open. Chinese fabs now have an alternative source, which means ASML's pricing power erodes and Western equipment makers need to compete harder on speed and capability — or lose volume in Asia.
