UBS: China Unlikely to Match ASML's Top-Tier EUV Lithography Machines Within a Decade
nashnova research
UBS says China's lithography technology sits roughly where ASML was twenty years ago, making a production-ready EUV alternative unlikely within the next decade — the core bottleneck for advanced chipmaking stays unresolved.
How far behind is China in lithography?
The UBS team led by François-Xavier Bouvignies puts it bluntly: China's current lithography stage roughly matches where ASML stood in 2004.
This means → ASML needed another fifteen years from that point to mass-produce EUV equipment; China faces a similar timeline.
The key evidence is patent activity, especially in light sources and laser subsystems — the two most critical modules inside an EUV lithography machine (a tool that uses extreme-ultraviolet light to etch circuits onto chips).
What can China achieve in the near term?
UBS expects China to reach high-volume manufacturing capability for immersion DUV lithography machines — one generation below EUV, but still an important chipmaking tool — within two to five years.
In plain terms = what China can build soon is "last-generation equipment," not the cutting edge.
The price gap tells the story: an ASML immersion DUV system costs roughly $90 million; an advanced EUV system tops $200 million — more than double the price, and a step-change in difficulty.
Even if China builds them, can they sell?
UBS is explicit: even with progress, the yield and throughput gap versus ASML remains vast.
Combined with U.S.-led export controls, the report concludes that "deployment of Chinese lithography equipment outside China is highly unlikely."
This reflects a deeper issue: lithography is not just about "can you build it" — it is about building it well enough, and finding buyers. Neither bar has been cleared.
What does this mean for the market?
ASML is the only company in the world capable of mass-producing advanced EUV lithography machines. Chips for Nvidia and others depend entirely on its equipment.
This means → that monopoly position will not be challenged in the foreseeable future; ASML's moat is wider than the market assumes.
For China, the core bottleneck in advanced chipmaking remains unresolved — Beijing continues pouring state capital into domestic chip self-sufficiency, but equipment is still the biggest chokepoint.
