China's Lithography Breakthrough Challenges Global Chip Supremacy Race
China has started making its own advanced machines that help create tiny computer chips.
These machines are called immersion DUV lithography machines.
Chinese scientists also say they are close to making even better machines called EUV, which can make the smallest chips.
The U.S. and its allies had put rules in place to stop China from buying the best machines from a Dutch company called ASML.
But China is building its own tools instead.
Big companies like ASML, Applied Materials, and Nvidia might have to compete with China’s new tools.
This could change how chips are made around the world.
China has begun mass‑producing domestic immersion DUV lithography machines.
Chinese researchers claim progress toward home‑made EUV lithography systems.
The breakthrough follows sanctions that limited China’s access to ASML EUV equipment.
China’s semiconductor ecosystem now includes major players like SMIC, Huawei, and CXMT.
Western companies such as ASML, Applied Materials, and Nvidia face new competition.
