TL;DR
China is actively working to develop its own advanced lithography machines, including EUV technology, in response to U.S. export controls. While progress is underway, achieving a fully independent, domestically-produced EUV remains uncertain.
China is actively working to develop its own EUV lithography machines as part of its broader strategy to achieve technological independence in chip manufacturing. This effort is driven by U.S. export restrictions that limit China’s access to advanced tools, including those from ASML, the global leader in lithography equipment. While China has made some progress with domestic projects, experts say building a fully functional, competitive EUV machine remains a complex, long-term challenge.
China’s top chipmaker, SMIC, and several other domestic firms like Huawei, SiCarrier, and Yuliangsheng are collaborating with research institutes and receiving government backing to develop lithography systems capable of rivaling international leaders. The Chinese government launched the third phase of its National Integrated Circuit Industry Investment Fund in May 2024, pledging 344 billion yuan ($48 billion) to foster domestic innovation.
Despite these efforts, experts emphasize the extreme complexity of EUV lithography technology. ASML’s CEO Christophe Fouquet highlighted that the company’s machines rely on a vast ecosystem of suppliers and specialized knowledge, making replication difficult. Andreas Erdmann from Fraunhofer IISB noted that building such machines requires mastery over optics, mechanics, electronics, chemistry, and computation—an integration that few companies worldwide can achieve.
China’s current lithography capability mainly involves older DUV (deep ultraviolet) systems, with SMEE producing 90-nm machines that are less advanced and still face operational issues, according to industry sources. The goal is to develop 65-nm, 28-nm, and ultimately EUV systems, but progress remains slow and uncertain, especially given U.S. restrictions on exporting critical components.
Why China’s Lithography Ambitions Matter
The development of a domestic EUV lithography machine would mark a significant breakthrough for China’s semiconductor industry, enabling it to produce advanced chips without reliance on foreign technology. This could shift the global supply chain and reduce U.S. leverage over China’s tech sector. However, experts warn that achieving a fully operational EUV machine domestically will take years, and the technical hurdles are formidable.
For global tech markets, China’s progress could influence supply chain dynamics, pricing, and geopolitical tensions. For China, success in this area is viewed as critical to advancing its technological independence and economic ambitions in high-tech manufacturing.

Background on China’s Chip Equipment Development
China has long depended on foreign equipment for advanced chip manufacturing, with U.S. export controls intensifying in recent years. The 2019 blocked shipment of ASML’s EUV machine to SMIC marked a turning point, prompting China to accelerate its domestic R&D efforts. Companies like SMEE, Huawei, and SiCarrier have been working on developing lithography systems, but their machines currently operate at less advanced nodes, such as 90 nm.
U.S. restrictions, including bans on exporting advanced lithography tools, aim to slow China’s progress toward cutting-edge chips, particularly at 7 nm and below. In response, China increased funding for its chip industry, including the Big Fund, with a focus on developing indigenous equipment and reducing reliance on foreign suppliers.
While China has made some technological strides, experts agree that building a competitive EUV lithography system remains a long-term goal, hindered by the immense complexity and the need for an integrated supply chain of specialized components.
“Most of the time the people working on the light source don’t know at all how the optic system is working, because these are very different domains of competence.”

Challenges in Achieving Fully Domestic EUV Lithography
It remains unclear whether China can successfully develop a fully operational, competitive EUV lithography machine in the near future. While progress is evident in lower-node lithography systems, the technical, supply chain, and intellectual property hurdles for EUV are substantial. Experts caution that even with significant investment, it could take years or decades before China achieves a breakthrough comparable to ASML’s capabilities.

Next Steps in China’s Lithography Development Race
China is expected to continue investing heavily in domestic lithography R&D, with increased collaboration between government agencies, research institutes, and private companies. Monitoring the progress of firms like Yuliangsheng and SiCarrier, as well as government funding allocations, will be key to assessing China’s potential breakthroughs. Internationally, export restrictions and technological embargoes are likely to persist, shaping the competitive landscape for years to come.

Key Questions
Can China currently produce EUV lithography machines?
No, China has not yet developed fully operational EUV lithography machines. Its efforts are focused on lower-node systems and ongoing R&D for EUV technology.
What are the main obstacles for China in building EUV lithography equipment?
The key challenges include the immense technical complexity, supply chain integration, and access to critical components and intellectual property, which are heavily restricted by export controls.
How might U.S. export restrictions impact China’s ambitions?
Restrictions limit China’s access to advanced tools and components, slowing progress and increasing reliance on domestic innovation efforts, which still face significant hurdles.
What is the significance of developing a domestic EUV machine for China?
Successfully developing a domestic EUV lithography machine would reduce dependence on foreign technology, enhance China’s semiconductor self-sufficiency, and potentially shift global supply chains.
