Chipmaker stocks decline as China begins manufacturing DUV lithography machines

The record

Written from the 2 reports below. Nothing here is unsourced.

Shares of major semiconductor companies including ASML, AMD, Micron, and SanDisk fell by as much as 12% after China announced it has begun mass producing its own deep ultraviolet (DUV) lithography machines.
DUV tools are essential for making most modern chips and have been a focal point of US-led export controls aimed at containing Beijing’s semiconductor ambitions.
The announcement signals that China may be able to bypass some of those restrictions, reducing its reliance on Western equipment makers like the Netherlands-based ASML.
Traders interpreted the development as a potential long-term headwind for incumbent Western chip-tool suppliers, even though analysts widely agree China's domestic machines are still less advanced than the best foreign tools.
The sell-off reflects market concerns about future market share and geopolitical friction rather than an immediate technological parity.
Investors and policymakers will now watch for independent verification of China's production yield and any follow-on export control adjustments from the US and allies.
