TL;DR
China is actively pursuing the development of its own EUV lithography technology to reduce reliance on foreign suppliers like ASML. While progress is underway, experts say building such machines is highly complex, and China faces significant technical and geopolitical hurdles.
China is actively working to develop its own extreme ultraviolet (EUV) lithography machines to achieve technological independence in chip manufacturing, amid U.S. export restrictions on leading foreign suppliers like ASML. This effort is critical for China’s goal of advancing its semiconductor industry and reducing reliance on foreign technology.
China’s top chipmaking companies, including SMIC and SMEE, are investing in developing lithography equipment capable of rivaling ASML’s EUV machines. Huawei and other firms are supporting research and development efforts, with some prototypes reportedly in progress. The Chinese government has also launched a substantial funding initiative, the third phase of its National Integrated Circuit Industry Investment Fund, with over 340 billion yuan ($48 billion) allocated to strengthen the domestic chip supply chain.
However, building EUValithography machines is an extremely complex challenge, involving advanced optics, mechanics, electronics, chemistry, and computational integration. Experts like Andreas Erdmann from Fraunhofer IISB emphasize that the development of such machines requires a level of expertise and industrial support that is rare globally. China’s current lithography tools are limited to older DUV (deep ultraviolet) systems, with SMEE’s latest machines capable of producing 90-nm chips—far less advanced than EUV technology.
Despite these hurdles, Chinese firms are collaborating to develop homegrown lithography systems with the support of research institutes and foreign talent, aiming eventually to produce EUV machines domestically. The ultimate goal is to establish a self-reliant ecosystem that can bypass U.S. restrictions and compete with global leaders.
Implications of China’s Lithography Ambitions for Global Tech
China’s pursuit of independent EUV lithography technology could significantly alter the global semiconductor landscape. Success would reduce China’s reliance on foreign suppliers like ASML, enhance its ability to produce advanced chips, and potentially challenge the current dominance of Western and Japanese equipment makers. It also raises geopolitical concerns, as control over critical manufacturing equipment is seen as vital for national security and technological sovereignty.
However, experts warn that the technical barriers are formidable, and China’s efforts may take years or decades to realize fully. The development of such complex machinery is not only a matter of funding but also of assembling a highly specialized workforce and establishing a robust innovation ecosystem. If China succeeds, it could accelerate its semiconductor self-sufficiency and reshape supply chains, but if it fails or faces delays, the current geopolitical tensions around chip technology are likely to persist.

Recent Developments and Challenges in China’s Lithography Efforts
Since the U.S. imposed export controls in 2019, restricting ASML from shipping EUV machines to China, Chinese companies have accelerated efforts to develop domestic lithography technology. SMEE, China’s primary lithography equipment maker, has produced systems capable of 90-nm chips, but these are far less advanced than EUV machines. Huawei has become a key supporter, investing heavily in R&D and recruiting talent from global leaders like TSMC and ASML.
Chinese authorities have prioritized semiconductor self-sufficiency, launching the third phase of the National Integrated Circuit Industry Investment Fund in May 2024, with a focus on developing lithography and other critical manufacturing equipment. Despite these efforts, experts acknowledge that the technical complexity of EUV lithography remains a major obstacle, and China’s progress is still at an early stage compared to established global leaders.
Internationally, the U.S. and allies continue to enforce export restrictions, aiming to slow China’s technological advancement in advanced chips. Meanwhile, Chinese firms are exploring alternative approaches, such as building less advanced DUV systems and collaborating with research institutes to gradually improve capabilities.
“Most of the time the people, for example, who worked on the light source don’t know at all how the optic system is working, because these are very different domains of competence.”

Technical and Political Barriers to China’s EUV Goals
While China’s efforts are progressing, it is still unclear how quickly and effectively it can develop fully operational homegrown EUV lithography machines. The technical challenges are immense, and international sanctions may continue to restrict access to critical components and expertise. It remains uncertain whether China can overcome these hurdles within the next decade or if external pressures will slow or halt progress altogether.

Next Steps in China’s Lithography Development Race
Chinese companies are expected to continue collaborating with research institutes and foreign talent to refine their lithography prototypes. The government’s increased funding and policy support aim to accelerate these efforts, but significant technical milestones must be achieved before domestically produced EUV machines can be commercially viable. Monitoring progress over the next 1-3 years will be key to assessing China’s trajectory in this field.

Key Questions
How close is China to producing an EUV lithography machine?
China is still in the early stages of development, with prototypes and systems capable of producing less advanced chips. Achieving a fully operational, competitive EUV machine is likely years away, given the technical complexity involved.
Why are U.S. restrictions affecting China’s lithography efforts?
The U.S. imposes export controls to limit China’s access to cutting-edge chip manufacturing equipment, aiming to slow its technological progress and maintain global semiconductor leadership.
Can China bypass U.S. restrictions through other means?
Chinese firms are developing alternative technologies and collaborating with domestic research institutes to reduce reliance on foreign equipment, but these efforts face significant technical hurdles.
What impact would a successful Chinese EUV machine have globally?
If China develops a viable EUV lithography system, it could challenge existing global leaders, reshape supply chains, and increase its strategic independence in semiconductor manufacturing.
