China’s semiconductor push has two very different timelines. Building a domestically competitive EUV lithography system remains a long-term challenge; building more self-sufficient supply for AI memory is becoming a nearer-term objective.
Zeiss Semiconductor Manufacturing Technology chief Frank Rohmund has described 15 years as a reasonable estimate for China to develop EUV lithography machines, while UBS analysis has similarly placed China at least a decade from a commercially competitive toolchain. Those are estimates rather than fixed deadlines, but they point to the same conclusion: demonstrating a machine is not the same as delivering an ASML-class production platform.
Why EUV is much harder than making a scanner
EUV is a complete manufacturing system, not a single piece of equipment. A competitive platform must combine a dependable light source, extremely precise optics, masks and pellicles, contamination control, metrology, software, field service and a supply chain capable of supporting high-volume fabs.
The commercial benchmark is demanding. A tool must deliver reliable throughput, overlay precision, uptime and repeatable results in customer production—not simply expose a wafer in a laboratory. That is why a domestic EUV prototype, if achieved, would not by itself close the gap with ASML.
China’s DUV progress is meaningful, but it is not EUV
China has made reported progress in immersion argon-fluoride deep-ultraviolet lithography, including work associated with Shanghai Micro Electronics Equipment (SMEE) on tools aimed around the 28 nm class. Immersion DUV is a significant capability because it can support advanced manufacturing through multi-patterning.
But multi-patterning adds exposures, masks and process steps. In practice, that raises process complexity and can increase cost and yield risk compared with using EUV for the relevant layers. A reported DUV milestone also should not be confused with demonstrated, high-volume output at the productivity and reliability expected from ASML’s established systems.
The distinction matters: China can improve domestic capacity and reduce exposure to foreign equipment constraints without immediately matching the technology used for the most advanced logic production.
Export controls slow the frontier—but may strengthen the domestic incentive
Restrictions have kept ASML’s EUV systems out of China and tightened access to the most advanced immersion-DUV tools. That limits China’s near-term access to equipment used for leading-edge production.
Rohmund’s argument against extending controls to older, legacy DUV systems is economic as well as strategic. Mature-node equipment serves a wide range of civilian chip production. Broader restrictions would reduce sales for equipment suppliers while increasing China’s incentive to replace overseas tools with domestic alternatives.
In that view, export controls can delay access to the technology frontier, but they do not automatically eliminate China’s motivation to develop substitutes. The key question is whether domestic suppliers can convert investment and prototypes into dependable, high-volume equipment.
CXMT’s HBM3E milestone matters on a faster timeline
China’s memory industry is moving on a different track. ChangXin Memory Technologies (CXMT) has reportedly begun small-scale production of HBM3E and supplied parts for testing with domestic AI-chip developers including Alibaba’s T-Head unit and Cambricon. The reported volumes remain limited, and its capability at production scale is still unproven. 8

That makes the development strategically important but not yet commercially equivalent to the leading suppliers. Samsung, SK hynix and Micron retain the established position in advanced HBM, while reports describe CXMT as working toward a production ramp after its initial small-batch phase. 6

For Chinese AI-accelerator developers, even an early domestic option could reduce supply-chain dependence and give local customers a path to qualification. For Samsung and SK hynix, the immediate competitive impact is likelier to be concentrated in China rather than the entire premium global HBM market.
The practical takeaway
China’s chip capabilities should not be assessed with one headline number. In lithography, the gap to a competitive EUV ecosystem remains very large: roughly a decade or more by the estimates discussed by Rohmund and UBS. In AI memory, CXMT’s HBM3E work shows that China can advance faster in selected parts of the supply chain.
The next evidence to watch is not a single prototype announcement. It is sustained proof of yield, reliability, customer qualification and manufacturing scale—whether for SMEE’s DUV equipment, a future domestic EUV platform, or CXMT’s HBM output.
