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.

Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.
◆ ◆ 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.
