TL;DR
China has begun mass-producing domestic DUV lithography machines and prototypes of EUV tools, signaling progress in chip manufacturing. However, significant gaps in yield, materials, and experience mean it will take years to reach commercial-scale, high-volume production.
China has begun mass-producing domestic immersion DUV lithography machines capable of manufacturing chips at 28 nanometers, with prototypes of EUV tools also under development, marking tangible progress in its semiconductor manufacturing capabilities.
Multiple credible sources confirm that China has started producing and deploying domestic immersion DUV lithography machines, which are capable of 28-nanometer manufacturing and, through multi-patterning, potentially reaching 7- and 5-nanometer nodes. These systems are primarily sourced domestically and evaluated at firms like SMIC and Huawei.
Reuters reports that China is developing a domestic EUV prototype, but it remains at an early stage. While these developments are significant, they do not yet translate into high-yield, large-scale production of advanced chips. SMIC, for example, reportedly achieves about 20% yield on 5-nanometer chips, far below the 90% typical of leading global fabs using EUV technology.
Several challenges remain, including dependency on imported ultra-pure materials like photoresist, which China sources mainly from Japan, and the technological lag of domestic tools, which are estimated to be four generations behind ASML’s current systems. Additionally, the installed base of DUV tools requires ongoing maintenance from Western suppliers, creating a dependency that hinders self-sufficiency.
Every few weeks a headline says China cracked the last hard problem in chipmaking — and triggers alarm in one camp, triumph in the other. Both overreact, because both mistake a learning-by-doing problem for a copying problem. It isn’t one.
▲ Forward-looking · figures are point-in-time estimates“A machine exists” and “a machine makes advanced chips at scale, profitably, for years” are separated by a chasm — made of things that only accumulate with time.
In a race, a burst of speed closes the gap. In a phase transition, you can’t move faster to cross over — you have to accumulate enough, slowly, until the system changes state.
When you see “China achieves X,” ask which of two very different claims is actually being made.
Even amid the loud headlines, the quiet data points all say the same thing.
No prototype, no shipped tool, no yield headline teleports past it.
Implications of China's Progress in Lithography Capabilities
This progress indicates that China is moving beyond theoretical development toward practical manufacturing, yet it still faces substantial hurdles before achieving reliable, high-volume production of advanced chips. The gap in yield, materials, and expertise means that, despite early successes, China remains years away from full self-sufficiency in cutting-edge semiconductor manufacturing. This ongoing transition influences global supply chains, technological sovereignty debates, and geopolitical considerations.

Key Factors Defining China's Semiconductor Learning Curve
Over the past decade, China has invested heavily in semiconductor research and manufacturing infrastructure, aiming to reduce reliance on Western technology. While it has made strides in developing domestic DUV tools and prototypes of EUV machines, experts agree that the core challenge lies in the tacit knowledge required for high-yield, reliable production. This knowledge is accumulated through years of experience, iterative process improvements, and extensive service and maintenance, much of which currently depends on Western suppliers like ASML.
Previous reports and industry assessments suggest that China is approximately four generations behind ASML’s leading EUV systems, with credible forecasts indicating it will take until around 2030 for domestic tools to reach sub-10 nanometers at commercial volumes. The current focus remains on scaling and improving yields, materials purity, and process stability.
"Progress in domestic lithography tools is real, but the leap from prototype to reliable, high-yield manufacturing is a multi-year process driven by accumulated tacit knowledge and experience."
— Thorsten Meyer
Unresolved Challenges in Achieving Commercial-Scale Production
It is still unclear how quickly China can improve yields, develop high-purity materials domestically, and establish a self-sustaining service ecosystem. The timeline for domestic tools to match the performance of Western systems remains uncertain, with forecasts suggesting significant progress by 2030 but no guarantees.
Next Milestones in China's Semiconductor Development Roadmap
China will likely continue scaling up domestic DUV production and refining process yields over the next few years. Efforts to develop and commercialize EUV prototypes will also intensify, with the goal of achieving reliable, high-volume manufacturing at sub-10 nanometers by the early 2030s. Monitoring advancements in materials independence and maintenance capabilities will be crucial to assessing progress.
Key Questions
How close is China to producing advanced chips at commercial scale?
While China has begun mass-producing 28-nanometer chips and prototypes of EUV tools, it remains years away from reliably manufacturing high-volume, sub-10 nanometer chips at high yields.
What are the main hurdles China faces in closing the lithography gap?
The primary challenges include achieving high yields, developing domestically sourced ultra-pure materials, and building self-sufficient maintenance and service capabilities for advanced tools.
Will China be able to catch up with leading chipmakers?
China is making deliberate progress, but experts estimate it will take until around 2030 for domestic tools to reach the performance levels of current leading systems, especially for sub-10 nanometer manufacturing.
How does this development affect global chip supply chains?
Progress in China’s lithography capabilities could diversify global supply sources and influence geopolitical negotiations, but significant gaps remain before China can independently produce cutting-edge chips at scale.
What is the significance of the learning-by-doing approach in this context?
The approach emphasizes that mastering advanced manufacturing requires years of iterative process improvements and tacit knowledge accumulation, which cannot be quickly copied or rushed.
