ASML built its first working prototype of EUV technology in 2001, and told Reuters it took nearly two decades and billions of euros in R&D spending before it produced its first commercially-available chips in 2019.
“It makes sense that companies would want to replicate our technology, but doing so is no small feat,” ASML told Reuters in a statement.
ASML's EUV systems are currently available to U.S. allies including Taiwan, South Korea, and Japan.
Starting in 2018, the United States began pressuring the Netherlands to block ASML from selling EUV systems to China. The restrictions expanded in 2022, when the Biden administration imposed sweeping export controls designed to cut off China's access to advanced semiconductor technology. No EUV system has ever been sold to a customer in China, ASML told Reuters.
The controls targeted not just EUV systems but also older deep ultraviolet (DUV) lithography machines that produce less-advanced chips like Huawei’s, aiming to keep China at least a generation behind in chipmaking capabilities.
The U.S. State Department said the Trump Administration has strengthened enforcement of export controls on advanced semiconductor manufacturing equipment and is working with partners "to close loopholes as technology advances.”
The Dutch Ministry of Defence said the Netherlands is developing policies requiring “knowledge institutions” to perform personnel screenings to prevent access to sensitive technology “by individuals that have ill intentions or who are at risk of being pressured.”
Export restrictions have slowed China's progress toward semiconductor self-sufficiency for years, and constrained advanced chip production at Huawei, the two people and a third person said.
The sources spoke on condition they not be identified due to the confidentiality of the project.
CHINA'S MANHATTAN PROJECT
One veteran Chinese engineer from ASML recruited to the project was surprised to find that his generous signing bonus came with an identification card issued under a false name, according to one of the people, who was familiar with his recruitment.
Once inside, he recognized other former ASML colleagues who were also working under aliases and was instructed to use their fake names at work to maintain secrecy, the person said. Another person independently confirmed that recruits were given fake IDs to conceal their identities from other workers inside the secure facility.
The guidance was clear, the two people said: Classified under national security, no one outside the compound could know what they were building—or that they were there at all.
The team includes recently retired, Chinese-born former ASML engineers and scientists—prime recruitment targets because they possess sensitive technical knowledge but face fewer professional constraints after leaving the company, the people said.
Two current ASML employees of Chinese nationality in the Netherlands told Reuters they have been approached by recruiters from Huawei since at least 2020.
Huawei did not respond to requests for comment.
European privacy laws limit ASML's ability to track former employees. Though employees sign non-disclosure agreements, enforcing them across borders has proven difficult.
ASML won an $845 million judgment in 2019 against a former Chinese engineer accused of stealing trade secrets, but the defendant filed for bankruptcy and continues to operate in Beijing with Chinese government support, according to court documents.
ASML told Reuters that it “vigilantly guards” trade secrets and confidential information.
"While ASML cannot control or restrict where former employees work, all employees are bound by the confidentiality clauses in their contracts," the company said, and it has "successfully pursued legal action in response to the theft of trade secrets.”

Reuters was unable to determine if any legal actions have been taken against former ASML employees involved in China’s lithography program.
The company said it safeguards EUV knowledge by ensuring only select employees can access the information even inside the company.
Dutch intelligence warned in an April report that China "used extensive espionage programmes in its attempts to obtain advanced technology and knowledge from Western countries," including recruiting "Western scientists and employees of high-tech companies.”
The ASML veterans made the breakthrough in Shenzhen possible, the people said. Without their intimate knowledge of the technology, reverse-engineering the machines would have been nearly impossible.
Their recruitment was part of an aggressive drive China launched in 2019 for semiconductor experts working abroad, offering signing bonuses that started at 3 million to 5 million yuan ($420,000 to $700,000) and home-purchase subsidies, according to a Reuters review of government policy documents.
Recruits included Lin Nan, ASML's former head of light source technology, whose team at the Chinese Academy of Sciences' Shanghai Institute of Optics has filed eight patents on EUV light sources in 18 months, according to patent filings.
The Shanghai Institute of Optics and Fine Mechanics did not respond to requests for comment. Lin could not be reached for comment.
Two additional people familiar with China’s recruitment efforts said some naturalized citizens of other countries were given Chinese passports and allowed to maintain dual citizenship.
China officially prohibits dual citizenship and did not answer questions on issuing passports.
Chinese authorities did not respond to requests for comment.
INSIDE CHINA'S EUV FAB
ASML's most advanced EUV systems are roughly the size of a school bus, and weigh 180 tons. After failed attempts to replicate its size, the prototype inside the Shenzhen lab became many times larger to improve its power, according to the two people.
The Chinese prototype is crude compared to ASML's machines but operational enough for testing, the people said.
China's prototype lags behind ASML's machines largely because researchers have struggled to obtain optical systems like those from Germany's Carl Zeiss AG, one of ASML's key suppliers, the two people said.
Zeiss declined to comment.
The machines fire lasers at molten tin 50,000 times per second, generating plasma at 200,000 degrees Celsius. The light is focused using mirrors that take months to produce, according to Zeiss' website.
China's top research institutes have played key roles in developing homegrown alternatives, according to the two people.
The Changchun Institute of Optics, Fine Mechanics and Physics at the Chinese Academy of Sciences (CIOMP) achieved a breakthrough in integrating extreme-ultraviolet light into the prototype's optical system, enabling it to become operational in early 2025, one of the people said, though the optics still require significant refinement.
CIOMP did not respond to requests for comment.
In a March online recruitment call on its website, the institute said it was offering "uncapped" salaries to PhD lithography researchers and research grants worth up to 4 million yuan ($560,000) plus 1 million yuan ($140,000) in personal subsidies.
Jeff Koch, an analyst at research firm SemiAnalysis and a former ASML engineer, said China will have achieved "meaningful progress” if the “light source has enough power, is reliable, and doesn’t generate too much contamination.”
"No doubt this is technically feasible, it's just a question of timeline," he said. "China has the advantage that commercial EUV now exists, so they aren't starting from zero."

To get the required parts, China is salvaging components from older ASML machines and sourcing parts from ASML suppliers through secondhand markets, the two people said.
Networks of intermediary companies are sometimes used to mask the ultimate buyer, the people said.
Export-restricted components from Japan’s Nikon and Canon are being used for the prototype, one of the people and an additional source said.
Nikon declined to comment. Canon said it was not aware of such reports. The Japanese Embassy in Washington did not respond to a request for comment.
International banks regularly auction older semiconductor fabrication equipment, the sources said. Auctions in China sold older ASML lithography equipment as recently as October 2025, according to a review of listings on Alibaba Auction, an Alibaba-owned platform.
A team of around 100 recent university graduates is focused on reverse-engineering components from both EUV and DUV lithography machines, according to the people.
Each worker's desk is filmed by an individual camera to document their efforts to disassemble and reassemble parts—work the people described as key to China's lithography efforts.
Staffers who successfully reassemble a component receive bonuses, the people said.
HUAWEI SCIENTISTS SLEEP ON-SITE
While the EUV project is run by the Chinese government, Huawei is involved in every step of the supply chain from chip design and fabrication equipment to manufacturing and final integration into products like smartphones, according to four people familiar with Huawei’s operations.
CEO Ren Zhengfei briefs senior Chinese leaders on progress, according to one of the people.
The U.S. placed Huawei on an entity list in 2019, banning American companies from doing business with them without a license.
Huawei has deployed employees to offices, fabrication plants, and research centers across the country for the effort. Employees assigned to semiconductor teams often sleep on-site and are barred from returning home during the work week, with phone access restricted for teams handling more sensitive tasks, according to the people.
Inside Huawei, few employees know the scope of this work. "The teams are kept isolated from each other to protect the confidentiality of the project," one of the people said. “ They don't know what the other teams work on.”
