China has begun manufacturing immersion deep ultraviolet lithography machines, challenging ASML's monopoly on advanced chipmaking equipment and triggering a 7% drop in ASML's stock amid broader sell-offs in chip equipment globally.

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 lock on advanced lithography just cracked. Chinese fabs can now build domestically without Western equipment, which means your supply chain to China becomes negotiable - and your customers in China may soon have no reason to buy from you at all.
