Introduction
China has reached a critical milestone in its semiconductor journey. For the first time, China’s First Advanced Lithography Machine is undergoing trials, opening the possibility of domestic AI chip production without complete reliance on foreign technology. If successful, this breakthrough could reshape the global chip race, weaken U.S. export control leverage, and put Beijing one step closer to technological self-reliance.

Quick Overview in 5 Points
SMIC leads the trial – Semiconductor Manufacturing International Corporation (SMIC) is testing a deep-ultraviolet (DUV) lithography machine built by Shanghai start-up Yuliangsheng.
Domestic production milestone – Most machine components are made in China, marking a significant reduction in reliance on ASML.
Bridge to advanced nodes – The machine is initially built for 28nm but can support 7nm through multi-patterning, and possibly 5nm at lower yields.
Challenges remain – Scaling to mass production and competing with ASML’s EUV tools will take years.
Future ambitions – SiCarrier, a shareholder in Yuliangsheng, is developing China’s first EUV tool under the code name “Mount Everest.”
SMIC’s Role in Testing China’s First Advanced Lithography Machine
At the heart of this trial is SMIC, China’s largest chip manufacturer. The company is running experiments with a domestically produced DUV lithography machine designed by Yuliangsheng, a young Shanghai-based semiconductor equipment start-up.
This development is more than symbolic—it demonstrates that China is no longer fully dependent on ASML for every generation of lithographic technology. While the current machine is not at EUV levels, it represents a foundational step for Beijing’s long-term semiconductor strategy.
Industry analyst Lin Qingyuan at Bernstein put it bluntly:
“If successful, it would represent an important step for Chinese companies, which could build on this breakthrough for more advanced machinery.”

The Backdrop: U.S. Export Controls and ASML Bottleneck
Since 2019, the U.S. has tightened restrictions on China’s access to advanced semiconductor manufacturing tools. The Netherlands, home to ASML—the world’s only EUV supplier—has aligned with Washington, effectively cutting Beijing off from the most advanced lithography machines.
Until now, Chinese fabs like SMIC relied heavily on:
- Older ASML DUV tools purchased before sanctions.
- Second-hand imports sourced through third countries.
- Shanghai Micro Electronics Equipment (SMEE), which only makes less advanced DUV systems.
This bottleneck has kept China several generations behind leaders like TSMC, which is preparing to mass-produce 2nm chips with ASML’s latest EUV tools this year.
Against this backdrop, China’s First Advanced Lithography Machine represents not just a technical achievement but a political statement: Beijing is determined to reduce its reliance on Western suppliers.

How the New Machine Works: DUV Immersion Technology
The Yuliangsheng tool being tested is a DUV immersion lithography machine, similar in concept to ASML’s immersion DUV systems. According to people familiar with the trials, SMIC is:
- Testing the machine at the 28nm level,
- Using multi-patterning techniques to produce 7nm chips,
- Experimenting with pushing yields down to 5nm, albeit with difficulty.
In semiconductor terms, 28nm is no longer cutting-edge—but multi-patterning allows fabs to print smaller geometries by running multiple exposures of the same wafer.
This technique is costlier and less efficient but still enables AI-grade processors like Huawei’s Ascend chips to be manufactured without EUV.

Can It Compete with ASML? The Challenges Ahead
Prototyping a lithography tool and mass-producing it at scale are two different challenges.
Key hurdles for Yuliangsheng and SMIC include:
- Yield optimization – It can take a year or more of fine-tuning to achieve yields viable for commercial mass production.
- Component sourcing – While most parts are now made in China, some high-precision optics and subsystems still rely on foreign imports.
- Reliability – Competing with ASML requires not only technical performance but also long-term operational stability, something Chinese tools are still proving.
Lin Qingyuan summarized the dilemma:
“It is one thing to have a prototype of a lithography machine, it is another thing to put it into volume production and make it compete with ASML. This could take another few years.”

SiCarrier’s EUV Ambitions: The “Mount Everest” Project
China’s ambitions do not stop at DUV. SiCarrier, a shareholder in Yuliangsheng and founded in 2021, has set its sights on developing a domestic extreme ultraviolet (EUV) lithography machine.
At the Shanghai Semicon Conference earlier this year, SiCarrier showcased entire product lines of chip manufacturing equipment named after famous Chinese mountains like Wuyi and Emei. Internally, their EUV project carries the codename “Mount Everest”—a nod to the scale and difficulty of the task.
Industry experts caution that China’s EUV program is still in early stages. However, the fact that resources are being pooled into this effort underscores Beijing’s determination to break free of ASML’s monopoly.

Why This Matters for AI Chipmaking
The race to control lithography technology is not just about bragging rights—it is central to the future of artificial intelligence.
- AI workloads demand advanced processors such as GPUs, AI accelerators, and custom ASICs.
- Nvidia, TSMC, and ASML dominate this supply chain, leaving China vulnerable to supply restrictions.
- China’s First Advanced Lithography Machine offers a potential pathway to secure domestic AI chip production—even if not at bleeding-edge levels like 2nm.
By 2027, SMIC and Chinese fabs plan to triple their production capacity, largely by combining stocked-up ASML DUV machines with new domestic tools. This would allow Chinese tech giants like Huawei, Baidu, and Tencent to sustain AI development even under ongoing U.S. restrictions.

The Road Ahead: From Trials to Mass Production
For now, the Yuliangsheng machine is at the trial stage inside SMIC facilities. According to people familiar with the matter:
- It will take at least a year before the machine is stable enough for reliable yields.
- Mass production using this tool may only begin by 2027.
- Early chips produced with it will likely remain at 7nm and 5nm nodes, not cutting-edge 3nm or 2nm.
Meanwhile, global competitors are not standing still. TSMC, Intel, and Samsung are moving toward 2nm and beyond, powered by ASML’s EUV leadership. That leaves China playing catch-up—but at least now, with China’s First Advanced Lithography Machine, it is playing the game on its own terms.

Conclusion: A Symbol of China’s Determination
The debut of China’s First Advanced Lithography Machine marks a historic step in the nation’s long journey toward semiconductor self-sufficiency. While challenges in mass production, component sourcing, and yield optimization remain, this milestone sends a clear signal: China is serious about competing in advanced chipmaking.
The coming years will decide whether China can turn prototypes into industrial-scale breakthroughs—or whether ASML’s dominance will continue unchallenged.
