China's state-backed Shanghai Micro Electronics Equipment (SMEE) has begun mass-producing immersion DUV lithography equipment, planning to supply five units in 2026 and 20 in 2027 to domestic chipmakers, triggering a sharp sell-off in ASML and global semiconductor stocks. Analysts note the immediate threat is limited due to performance and reliability gaps, but the move signals a long-term challenge to ASML's dominance if Chinese technology matures.
This Wire brief sits within Fusion42's coverage of Semiconductors, and 5 sources have reported it between 27 Jul 2026 and 28 Jul 2026.
◆ ◆ The Wire takeaway
ASML's pricing power in China just cracked. Chinese chipmakers can now buy domestic DUV equipment that works at 28nm, which means ASML loses leverage on every renewal negotiation in the world's largest semiconductor market—and if SMEE reaches 7nm in three years, ASML's China revenue becomes a hostage.
