Introduction
China is racing to become self-sufficient in semiconductor chip manufacturing, and one crucial frontier remains out of reach: China’s EUV lithography. As the cornerstone for making cutting-edge chips under 7 nanometers, EUV (Extreme Ultraviolet) systems are essential for powering AI, 5G, smartphones, and next-generation computing.
Currently, only one company in the world—ASML of the Netherlands—makes EUV lithography machines. These ultra-complex tools are blocked from export to China due to U.S.-led restrictions. In response, Beijing is pouring billions into building its own version of ASML. But the question remains: Can China build its own EUV machine and truly rival ASML?
This article explores the answer.

Quick Snapshot: China’s EUV Challenge in 5 Points
Massive Investment: China is investing over $41 billion into domestic EUV development through government-led programs.
Strategic Goal: Building a 100% self-reliant chip ecosystem—free from U.S. tech bans—is now a national priority.
Technical Bottlenecks: EUV demands near-perfect optics, powerful light sources, and thousands of complex subsystems.
Key Players: Companies like SMEE, Huawei, and Naura, and institutions like the Harbin Institute of Technology are leading the charge.
Timeline: China aims for EUV trial production by late 2025, with hopes of commercial rollout in 2026–2027.
Why EUV Technology Is Crucial
EUV lithography enables chipmakers to print circuit lines as small as 13.5 nanometers, which is required for sub-7nm chips. These chips are used in:
- Artificial intelligence (AI) accelerators
- High-performance computing (HPC)
- 5G modems and RF chips
- Smartphones and tablets
- Data centers and cloud servers
Without EUV, China’s foundries like SMIC are stuck using older DUV (deep ultraviolet) techniques, which are costly and inefficient for advanced nodes.

ASML: The Fortress China Wants to Breach
ASML holds a monopoly on EUV systems, with a market value of over $400 billion.
Its machines, built using parts from Zeiss, Trumpf, and Cymer, cost more than $200 million each and involve over 100,000 components.
The U.S. has blocked ASML from selling EUV tools to China since 2019.
Because of this, China’s strategy is simple but ambitious: build its own ASML—an indigenous EUV ecosystem that removes foreign dependency entirely.

China’s Plan: Funding, Firms, and Focus
Beijing is backing domestic EUV development with:
- Big Fund III: A new $50 billion chip investment fund focused on tools and design software.
- €37 billion EUV-specific investment: Pledged to support lithography, light sources, optics, and photoresist R&D.
- Provincial-level subsidies: Local governments are investing in academic–industry partnerships and tool development labs.
Major Players:
| Company / Institute | Contribution |
|---|---|
| SMEE (Shanghai Micro) | China’s leading lithography toolmaker, working on DUV to EUV shift |
| Huawei / SiCarrier | Funding light source innovation, conducting EUV testing |
| Harbin Institute of Tech | Developed a discharge plasma EUV light source |
| Chinese Academy of Sciences | Led by ex-ASML scientist Lin Nan, working on solid-state EUV lasers |
Technical Hurdles Still Loom Large
EUV isn’t just expensive—it’s scientifically demanding. Here are the major technical gaps:
| Technical Area | Challenge |
|---|---|
| Light Source | ASML uses laser-produced plasma (LPP); China is testing discharge plasma (LDP), which is less proven at scale. |
| Optics | EUV mirrors require atomic-level precision. Germany’s Zeiss still dominates this area. |
| Photoresist | Chemicals used in chip printing are dominated by Japanese firms like JSR. China is developing its own, but results are mixed. |
| System Integration | EUV machines combine robotics, vacuum systems, optics, and software. All must work flawlessly together. |
| Mass Production Yield | A tool might work in the lab, but getting high-yield, high-throughput performance for commercial fabs like SMIC is a different game entirely. |
Recent Developments: Signs of Progress
China has made some notable advances:
- In early 2025, Huawei and SiCarrier began testing an LDP-based EUV prototype. Trial production is expected in Q3 2025, with potential rollout by late 2026.
- SMEE announced new immersion DUV tools in 2024 and has filed several patents related to EUV.
- The Harbin Institute claims their light source design offers better energy efficiency and cost-effectiveness than Western LPP systems.
- China’s local chip toolmakers’ market share rose to 11.3% in 2024, up from just 5.1% in 2020.

Global Impact: What Happens if China Succeeds?
If China’s builds its own EUV lithography machine, the ripple effects will be massive:
- Breaks ASML monopoly
- Redraws the global chip supply chain
- Accelerates U.S.–China tech rivalry
- Strengthens China’s AI and defense capabilities
- Reduces dependency on Western allies like Taiwan, Japan, and South Korea
But experts caution that even if China deploys EUV machines, matching ASML’s throughput, stability, and uptime could take another 5–10 years.

Conclusion
China’s journey to develop an EUV lithography machine is one of ambition, urgency, and geopolitical weight.
It reflects not just a technological race, but a battle for digital sovereignty. The funding is there. The motivation is strong. The early lab results are promising.
But the true challenge lies in scaling, integrating, and manufacturing EUV systems that rival ASML’s precision and reliability.
