The US’s Worst Fear? China Reportedly Builds First Domestic EUV Prototype
Wednesday, December 17, 2025SEMICONDUCTOR BREAKTHROUGH
In a development that has sent shockwaves through the global tech industry, reports indicate that China has successfully built its first domestic Extreme Ultraviolet (EUV) lithography prototype. This marks a critical turning point in the high-stakes "chip war," moving Beijing one step closer to breaking its reliance on Western technology.
For years, the U.S. and its allies have used export controls to block China from acquiring EUV machines—the multi-million dollar systems manufactured exclusively by the Dutch firm ASML. These machines are the only way to produce the world's most advanced 3nm and 2nm chips. Now, that blockade may have a massive crack in it.
The "Impossible" Prototype
According to reports from Reuters and Wccftech, Chinese engineers have developed a prototype that is reportedly fully operational and capable of generating the specific UV light required for wafer etching. While the machine has not yet "taped out" a finalized chip, the speed of development has stunned analysts.
Beating the Odds
Only months ago, ASML CEO Christophe Fouquet predicted that it would take China "many, many years" to replicate this technology. The existence of a functioning prototype suggests that China’s aggressive talent poaching and reverse-engineering efforts are paying off much faster than anticipated.
Companies like SMIC and Huawei have been working in a clandestine network of "shadow fabs" across the country. Their goal is simple: total semiconductor independence. If China can scale this EUV technology, the U.S. sanctions intended to freeze China’s AI and military capabilities could become effectively obsolete.
Analysis Note: While this is a prototype, the transition from lab to factory floor is often the hardest part. However, with the 2030 goal now looking realistic, the semiconductor landscape is about to become a lot more crowded.
What Happens Next?
The U.S. is expected to respond with even tighter restrictions, potentially targeting the secondary market for older machine parts that China is reportedly using to build these prototypes. For now, all eyes are on the first "test chips" expected to come off this new machine.
If China reaches the 5nm or 3nm threshold without ASML's blessing, the global balance of technological power will shift permanently.
