It was built by a team of former engineers from Dutch semiconductor giant ASML who reverse-engineered the company’s extreme ultraviolet lithography (EUV) machines, according to two people with knowledge of the project. EUV machines sit at the heart of a technological Cold War. Until now, only one company has mastered EUV technology: ASML, headquartered in Veldhoven, Netherlands. ASML built its first working prototype of EUV technology in 2001. No EUV system has ever been sold to a customer in China, ASML told Reuters.
