China’s reported development of a prototype extreme ultraviolet (EUV) lithography machine in a high-security Shenzhen laboratory marks a potentially pivotal moment in the global semiconductor contest. If the project succeeds, it could weaken a core pillar of Western technological dominance and redraw the geopolitics of advanced chipmaking that underpins artificial intelligence, smartphones, and modern military systems.
Why EUV Lithography Matters So Much
EUV lithography is the most advanced method used to manufacture cutting-edge semiconductor chips. It enables the etching of circuits thousands of times thinner than a human hair onto silicon wafers, allowing more transistors to be packed into a chip and dramatically boosting computing power. Until now, this capability has been monopolised by a single company: of the Netherlands. Its EUV machines are indispensable for producing the world’s most advanced chips used by firms such as Nvidia and AMD, and manufactured by foundries like TSMC, Intel, and Samsung.
What China Has Reportedly Achieved
According to investigative reporting, Chinese scientists have built a large, factory-scale EUV prototype that is already operational in one crucial sense: it can successfully generate extreme ultraviolet light. This places China several steps closer to mastering the most complex part of EUV technology. However, the machine has not yet produced working chips, indicating that significant hurdles remain in optics, precision control, and contamination management. Chinese planners have reportedly set a target of producing chips by 2028, though insiders see 2030 as more realistic.
A State-Led Drive for Semiconductor Self-Reliance
The project is part of a broader, six-year push to achieve semiconductor self-sufficiency, a strategic priority strongly associated with President . Oversight of China’s semiconductor strategy has been linked to senior leadership figures such as , reflecting how closely the effort is tied to national security. Major Chinese firms, especially , are reported to coordinate networks of state research institutes and industrial partners, mobilising thousands of engineers across the country.
The Talent and Technology Question
One striking aspect of the Shenzhen project is its reliance on former ASML engineers, including retired or Chinese-born specialists with deep knowledge of EUV systems. Their expertise has reportedly enabled reverse-engineering efforts that would otherwise have been nearly impossible. This recruitment drive reflects China’s broader strategy since 2019 to attract overseas semiconductor talent through large financial incentives and state backing, raising persistent concerns in Europe about technology leakage and enforcement of non-disclosure agreements.
Why the West Tried to Stop This
Since 2018, the United States has pressured the Netherlands to block ASML from exporting EUV systems to China. These restrictions expanded in 2022 into sweeping export controls aimed at keeping China at least a generation behind in advanced chipmaking. The logic was strategic: denying EUV technology would constrain China’s progress in AI, supercomputing, and advanced weapons systems. The emergence of a domestic Chinese prototype suggests these controls may have slowed—but not fully stopped—China’s ambitions.
Technical Bottlenecks Still Remain
Despite the breakthrough, China continues to lag behind ASML in critical areas, especially precision optics. ASML’s systems rely heavily on ultra-high-quality mirrors and optical components supplied by specialised Western firms, particularly Germany’s Carl Zeiss. Replicating these components requires extraordinary manufacturing precision and long production cycles. Chinese research institutes have made progress, but the current prototype is reportedly far larger and cruder than ASML’s machines, reflecting trade-offs made to achieve basic functionality.
Broader Geopolitical Implications
If China eventually succeeds in building a fully functional, domestically produced EUV machine, it would mark a major shift in the global technology balance. Semiconductor supply chains would become more fragmented, export controls less effective, and the ongoing technology rivalry between China and the West far more intense. For the United States and its allies, the episode underlines the limits of containment strategies in a world where knowledge, talent, and reverse-engineering can cross borders even when machines cannot.
