China has reportedly developed a working prototype of an extreme-ultraviolet (EUV) lithography machine, a critical technology for producing advanced AI chips. The development was disclosed on December 17, 2025, in an exclusive Reuters report, based on confidential sources with direct knowledge of the project. The prototype, constructed in a high-security lab in Shenzhen, can generate EUV light, a core requirement for etching the tiny circuits that power modern semiconductors.
The project has been described as a “Manhattan Project” for Chinese semiconductor technology, underscoring the scale, secrecy, and strategic importance assigned to it by Beijing. Like its atomic-era namesake, the initiative combines top government backing, state research institutes, and recruited foreign expertise. Reuters reports that former engineers from Dutch chipmaker ASML, the world’s sole producer of commercial EUV machines, were covertly brought in to accelerate China’s efforts.
While the prototype represents a technological milestone, it is not yet capable of producing functional chips. Experts caution that manufacturing operational AI-grade semiconductors requires additional precision optics and integration that China has yet to master. Even so, the development signals a major push toward technological self-reliance amid U.S. and Western export restrictions on advanced chipmaking technology.
Building a national project in secret
China’s effort began around 2019 as part of a state-backed strategy to reduce reliance on Western firms for advanced semiconductors. The initiative is coordinated by research institutes, including the Changchun Institute of Optics, Fine Mechanics and Physics, and involves private tech firms such as Huawei, which provides expertise in integration and chip design. The operation is reportedly conducted under extreme secrecy, with laboratory personnel using false identities and compartmentalized access.
The prototype reportedly occupies nearly an entire factory floor and has achieved the generation of EUV light, a critical step previously monopolized by Western manufacturers. According to Reuter’s sources, the development demonstrates China’s rapid capability acquisition, leveraging both domestic engineering and foreign knowledge. However, several critical components, including the highly precise lenses produced by firms like Carl Zeiss, remain unavailable domestically, meaning the prototype cannot yet fabricate finished chips.
This secrecy and technical ambition are key reasons why the Reuters story is an exclusive. Most details of the project, including the involvement of foreign engineers and progress milestones, had not been publicly reported. The disclosure provides unprecedented insight into China’s high-priority effort to compete with Western dominance in semiconductor production.
Technical Milestones and Challenges
Generating EUV light is a major technical barrier that previously limited semiconductor production to a few Western firms. China’s achievement is notable because EUV systems require extreme precision, ultra-clean vacuum systems, and complex optical pathways. According to Reuters sources, China has successfully built a machine that produces EUV light, but achieving consistent chip fabrication will require further development, especially in precision lenses and defect control.
Even experts cautious of overstatement acknowledge the symbolic importance: achieving EUV light generation in a domestic prototype indicates that China is closer than ever to producing advanced AI chips independently. Analysts suggest that, if successful, this could accelerate Beijing’s push for technological self-sufficiency, reduce reliance on Western suppliers, and mitigate the impact of ongoing U.S. export controls.
Despite this, insiders warn that mass production remains years away. Some estimates place functional chip output via a fully operational Chinese EUV system around 2030, although official targets from the government aim for earlier milestones by 2028.
Global implications
The prototype EUV development has significant geopolitical and market implications. EUV machines are critical for producing chips used in AI, high-performance computing, and advanced military systems. By moving closer to domestic production, China could shift the balance of global semiconductor supply, challenging the dominance of firms in the Netherlands, South Korea, Taiwan, and the U.S.
Western governments have long imposed restrictions on selling advanced chipmaking equipment to China. The Reuters report suggests that China may be circumventing these restrictions by reverse-engineering older systems and combining domestic innovation with recruited expertise. This raises concerns about the effectiveness of export controls and signals a potential acceleration in the tech race for AI chip supremacy.
Markets are unlikely to see immediate effects, as the prototype is not yet producing chips. However, long-term implications include potential reduced dependence on foreign semiconductors, expanded domestic AI capabilities, and greater strategic leverage for China in global technology negotiations.
The “Manhattan Project” analogy
The initiative has been likened to a Manhattan Project for AI chips, emphasizing the scale, secrecy, and government prioritization. Like the U.S. project during World War II that developed the atomic bomb, this effort combines intense government support, cutting-edge science, and tight security, aiming for a breakthrough that could redefine global technology leadership.
China’s project underscores its long-term strategy to achieve technological independence, especially in AI and semiconductors, sectors considered essential for economic competitiveness and national security. Even if practical mass production is still years away, the prototype demonstrates a significant capability leap, raising both commercial and geopolitical stakes.
China’s leap toward semiconductor independence
China’s development of a prototype EUV lithography machine represents a major milestone in its ambition to build advanced AI chips domestically. While the technology is not yet producing chips, it shows significant progress toward reducing dependence on Western suppliers, overcoming decades of technological gaps, and positioning China for long-term leadership in AI hardware.
The effort, combining state support, research institutions, and foreign expertise, highlights both technical ingenuity and strategic urgency. Analysts and global observers will be watching closely over the next several years to see if China can translate this prototype into functional, high-volume production, which would fundamentally reshape the global semiconductor and AI landscape.
Frequently asked questions
Why is EUV lithography so important?
EUV machines are essential for producing cutting-edge semiconductors used in artificial intelligence, data centers, smartphones, and advanced military systems. Without EUV, it is extremely difficult to manufacture chips at the most advanced nodes.
Why is this project described as a “Manhattan Project”?
The term reflects the scale, secrecy, and strategic importance of the initiative. Like the original U.S. Manhattan Project, it is heavily state-backed, tightly controlled, and aimed at achieving a breakthrough with major geopolitical consequences.
Is China already producing advanced AI chips with this technology?
No. The prototype can generate EUV light, which is a major milestone, but it cannot yet produce finished chips. Key components and production reliability are still missing.
