China has quietly developed a prototype extreme ultraviolet lithography machine in a state-backed effort to break Western dominance in advanced semiconductor manufacturing, marking a significant step in its long-term push for technological self-sufficiency.
In a highly secured laboratory in Shenzhen, engineers have built a full-scale prototype capable of generating extreme ultraviolet (EUV) light, a core technology used to fabricate the most advanced chips powering artificial intelligence, smartphones, and modern defence systems. While this machine has not yet produced functional chips, it represents a major milestone in China’s semiconductor programme, sources familiar with the project told Reuters.
The initiative, often compared to the historical Manhattan Project for its strategic importance, began in 2019 and is aimed at overcoming long-standing barriers imposed by export controls and global supply chain restrictions. EUV lithography technology has been largely monopolised by Western companies, particularly Dutch firm ASML, whose machines are critical for manufacturing cutting-edge processors.
A team including former engineers from Western semiconductor firms worked under tight confidentiality to reverse-engineer components and integrate them into China’s prototype. Recruitment of overseas talent, sometimes under alias identities, and reverse engineering using parts harvested from older European machines were key aspects of the project.
Chinese authorities have not publicly commented on the system, but industry participants said the government has set ambitious internal targets to achieve commercial production of advanced chips by around 2028, with some analysts suggesting 2030 may be a more realistic timeline. Achieving such capability domestically would significantly reduce dependence on foreign technology and contribute to national strategic resilience.
Huawei has played a prominent role in coordinating research institutes and production facilities across the country, aligning chip design and manufacturing efforts. This reflects China’s broader industrial strategy to upskill its semiconductor ecosystem — from core intellectual property and design to fabrication and systems integration.
To date, export restrictions by the United States and its allies have limited China’s access to the most advanced equipment, yet Beijing’s combination of state support, reverse engineering, and targeted recruitment has pushed progress faster than many analysts anticipated. Continued refinement of precision optical components remains a major technical challenge, but the prototype’s successful generation of EUV light suggests China is narrowing the gap with Western technology leaders.
The development of this lithography machine is part of China’s broader national push to cultivate a self-reliant semiconductor industry, a priority underscored by ongoing investment funds and policy initiatives aimed at reducing reliance on imported technology across critical high-tech sectors.
