China Achieves Major Breakthrough in Developing Domestic EUV Lithography Technology
Key Takeaways
- China has built a functional EUV lithography prototype capable of generating extreme ultraviolet light
- The prototype represents a major advance toward semiconductor self-sufficiency despite U.S. sanctions
- Full commercial production remains years away, but experts see potential for a more competitive global chip market
- The project involves thousands of engineers working in tightly controlled teams under government oversight
- Success could weaken U.S. and allied control over advanced chip technology and reduce sanction impacts
In a secure laboratory in Shenzhen, Chinese scientists have achieved a quiet but major breakthrough by developing a working prototype of an extreme ultraviolet (EUV) lithography machine. This critical piece of equipment is essential for manufacturing the world's most advanced semiconductor chips and has historically been controlled by a single Dutch company.
According to Reuters, China completed construction of this EUV prototype in early 2025 and is currently testing its capabilities. Though the massive machine—large enough to occupy nearly an entire factory floor—has not yet produced functional chips, it has successfully generated EUV light. This accomplishment demonstrates that China is far closer to achieving chip self-reliance than many experts previously believed.
EUV lithography technology uses beams of extreme ultraviolet light to etch circuits thousands of times thinner than a human hair onto silicon wafers. These machines are vital for producing cutting-edge chips used in artificial intelligence systems, smartphones, and advanced military technology. Until now, only ASML, a Dutch company, has mastered this technology, with each machine costing approximately $250 million and being indispensable for leading chip manufacturers such as TSMC, Intel, and Samsung. Notably, no EUV machines have ever been legally sold to China.
China's EUV project forms part of a comprehensive six-year government initiative aimed at attaining semiconductor independence—a key objective for President Xi Jinping. Led by top officials and coordinated by Huawei, the effort spans chip design, manufacturing equipment development, and finished product production. Often compared to the Manhattan Project, this massive, covert initiative involves thousands of engineers working in small, tightly controlled teams. Many Huawei engineers reportedly operate on-site with restricted communication and limited awareness of other teams' activities.
Despite facing stringent U.S. sanctions that have targeted Chinese technology since 2018 and expanded in 2022, China has pressed forward with its EUV development. These export controls were intended to keep China at least one generation behind in advanced chip manufacturing, but the recent breakthrough suggests progress continues regardless. Chinese researchers reportedly obtained components for the EUV prototype from older ASML machines available on the secondary market, often through intermediaries, and utilized parts from Japanese firms such as Nikon and Canon that remain subject to export restrictions.
While China's current EUV prototype lags behind ASML's commercial systems in size, refinement, and precision optics, it represents a significant step forward. Although the machine can generate EUV light, it still requires substantial further development to reliably produce chips. Experts estimate that the government's goal of achieving functional chip production by 2028 may be optimistic, with 2030 appearing more realistic.
If China succeeds in developing commercially viable EUV technology, it could diminish U.S. and allied dominance over advanced chips and lessen the impact of existing sanctions. The successful prototype indicates that the technological gap is narrowing faster than anticipated, pointing toward a more competitive and uncertain global semiconductor industry.
