China Reportedly Builds Secret ‘Manhattan Project’ EUV Machine for Chip Manufacturing

Defying years of Western sanctions, Chinese engineers have reportedly built an operational prototype of an extreme ultraviolet (EUV) lithography machine. Described by insiders as a “Manhattan Project” for chip sovereignty, the secret project relies heavily on former employees of Dutch giant ASML.

Located in a high-security Shenzhen facility, the machine generates the specialized light needed to print chips under 7 nanometers. While not yet producing working silicon, the development suggests Beijing is bypassing the U.S. blockade far faster than analysts predicted.

Orchestrated by Huawei and state officials, the effort reportedly uses aliases to obscure the involvement of Western-trained talent. Success here would neutralize the primary choke point in the global semiconductor war.

Inside the ‘Manhattan Project’: Secrecy and Espionage

Operating deep within a secure compound in Shenzhen, the initiative functions with a level of secrecy typically reserved for military weapons programs.

The prototype is a behemoth, reportedly filling an entire factory floor to accommodate the complex array of lasers, mirrors, and power supplies required to generate extreme ultraviolet light.

Development has moved at a breakneck pace. While ASML spent nearly two decades refining its technology, engineers reportedly completed their working prototype in early 2025, just six years after the government launched the initiative.

According to the exclusive report by Reuters:

“Completed in early 2025 and now undergoing testing, the prototype fills nearly an entire factory floor. It was built by a team of former engineers from Dutch semiconductor giant ASML who reverse-engineered the company’s extreme ultraviolet lithography machines or EUVs, according to two people with knowledge of the project.”

“The breakthrough marks the culmination of a six-year government initiative to achieve semiconductor self-sufficiency, one of President Xi Jinping’s highest priorities. While China’s semiconductor goals have been public, the Shenzhen EUV project has been conducted in secret, according to the people.”

To achieve this velocity, recruiters targeted a specific vulnerability in the Western supply chain: human capital. Aggressive headhunting campaigns focused on Chinese-born engineers working for ASML, offering signing bonuses ranging from 3 million to 5 million yuan ($420,000 to $700,000) alongside generous housing subsidies.

Strategic goals for the project are absolute. An insider familiar with the program outlined the ultimate objective, noting that “the aim is for China to eventually be able to make advanced chips on machines that are entirely China-made. China wants the United States 100% kicked out of its supply chains.”

Operational security within the facility is paramount to prevent identification by Western intelligence or former employers. Recruits are reportedly issued identification cards with aliases upon arrival, a tactic designed to sever any paper trail linking them to the project.

The investigation revealed specific details regarding the use of aliases:

“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.”

Work culture at the facility is described as intense and militaristic. Huawei, the telecommunications giant that has become the central coordinator of China’s semiconductor ambitions, manages the daily operations.

To maintain this breakneck development pace, Huawei has reportedly implemented a grueling, quasi-military work culture across its nationwide network of research centers and fabrication plants.

Acting as the project’s central coordinator, the company has instituted a “closed-loop” management system where semiconductor teams are effectively sequestered to maximize productivity and minimize leaks. Engineers are often required to sleep in on-site dormitories and are barred from returning home during the work week.

Security protocols are equally draconian, with teams handling the most sensitive technical data facing strict communication blackouts, including total bans on personal phone usage while inside the facilities.

The Engineering Gap: Generating Light vs. Printing Chips

Despite the breakthrough, a significant chasm remains between generating EUV light and mass-producing functional semiconductors.

Generating the necessary wavelengths involves punishing physics, requiring lasers to strike molten tin droplets 50,000 times per second to create plasma hotter than the surface of the sun.

Plasma temperatures in the process reach 200,000 degrees Celsius, a thermal environment that degrades components rapidly. While the Shenzhen prototype has successfully generated the necessary light, it has not yet printed a working chip, a milestone that requires sub-nanometer precision in wafer alignment.

Acknowledging the extreme difficulty of the task, the Dutch company noted that “it makes sense that companies would want to replicate our technology, but doing so is no small feat.”

Optical systems remain the primary bottleneck for the Chinese team. Replicating the ultra-flat mirrors supplied to ASML by Germany’s Carl Zeiss AG has proven exceptionally difficult.

Key research bodies like the Changchun Institute of Optics (CIOMP) and the Shanghai Institute of Optics are leading the effort to develop domestic equivalents, but the gap in precision manufacturing persists.

To bridge this gap, engineers have reportedly resorted to cannibalizing older ASML machines and sourcing restricted parts through a clandestine network of secondary markets and intermediaries.

Conflicting timelines have emerged regarding when the machine will be production-ready. Government mandates have set a target of 2028 for working chips, but insiders suggest 2030 is a more realistic horizon given the engineering hurdles.

Independent experts view the progress as significant regardless of the exact date. Assessing the technical landscape, Jeff Koch, an analyst at research firm SemiAnalysis and a former ASML engineer, observed that “no doubt this is technically feasible, it’s just a question of timeline. China has the advantage that commercial EUV now exists, so they aren’t starting from zero.”

Geopolitical Fallout: The Failure of Containment

Building a domestic EUV prototype fundamentally challenges the core premise of U.S. export controls, which aimed to freeze China’s logic chip capabilities at the 7nm or 14nm node. Washington’s strategy has relied on the assumption that without ASML’s machines, China would hit a hard technological ceiling.

Recent U.S. policy has fractured in response to these shifting realities. Under new directives, the Trump administration approved the H200 export tariff, allowing sales of older chips subject to a 25% tax, while simultaneously maintaining a strict ban on the cutting-edge Blackwell architecture.

Beijing has responded with a “rip and replace” mandate. As detailed in the ban on foreign chips, state-funded data centers are now required to remove all foreign hardware, effectively locking U.S. firms out of the government market.

Nvidia has borne the brunt of this decoupling. Describing the collapse of his company’s position in the region, CEO Jensen Huang lamented that “we went from 95% market share to zero percent, and so, I can’t imagine any policymaker thinking that that’s a good idea.”

While the domestic EUV project matures, Chinese firms have relied on illicit channels to bridge the gap. Reports of DeepSeek’s clandestine Blackwell acquisition highlight how smuggling rings and cloud loopholes are being used to access restricted compute power.

Developing the means of production represents a structural shift away from such stopgap measures. By mastering the manufacturing process, Beijing aims to eliminate the need for smuggling entirely.

Washington remains steadfast in its denial strategy for top-tier silicon. Confirming the administration’s hardline stance, White House spokeswoman Karoline Leavitt previously stated that “as for the most advanced chips, the ‘Blackwell’ chip, that’s not something we’re interested in selling to China at this time.”

This bifurcation creates a confusing regulatory environment where older silicon is treated as a taxable commodity, while cutting-edge processors remain strictly classified as contraband.

By imposing tariffs on legacy exports, the White House aims to extract revenue from China’s demand without surrendering the strategic high ground.

The Road Ahead: Yields, Subsidies, and Sovereignty

Transitioning from a prototype to high-volume manufacturing (HVM) is known in the industry as the “valley of death.” Yield rates for the first generation of domestic EUV machines will likely be phenomenally low, making the chips they produce exponentially more expensive than Western equivalents.

State subsidies will be critical to bridging this economic viability gap. Just as SMIC is currently testing the first homegrown DUV machine despite lower efficiencies, the Chinese government appears willing to absorb the costs of low yields to secure technological independence.

Huawei is acting as the system integrator for this new “Red Supply Chain.” By aligning its Ascend chip designs with SMIC’s fabrication capabilities and the new domestic equipment, the company is building a vertical stack completely insulated from U.S. sanctions.

Nvidia’s CEO has repeatedly warned Western stakeholders not to dismiss this competitive threat. Reflecting on the resilience of his rivals, Huang cautioned that “it is foolish to underestimate the might of China and the incredible competitive spirit of Huawei. This is a company with extraordinary technology.”

Geopolitically, the semiconductor market is bifurcating into two distinct technological spheres. As China’s domestic ecosystem matures, the leverage held by Western equipment makers like ASML and chip designers like Nvidia is eroding.

ASML has already signaled this shift to investors in October, warning of a significant sales drop in China as the country turns inward.

For Beijing, the cost of this independence is irrelevant compared to the strategic value. Capturing the national sentiment, Huawei founder Ren Zhengfei proclaimed that “China will break all restrictions to achieve great rejuvenation.”

Such a declaration signals the end of a unified global technology market. If Beijing succeeds in breaking the blockade, Western sanctions will lose their primary leverage, transforming the current trade dispute into a permanent, parallel cold war where interoperability is replaced by incompatibility.
