TL;DR
China has begun mass-producing domestic immersion DUV lithography machines capable of manufacturing chips at 28-nanometer nodes, with prototypes of advanced EUV machines. However, challenges like low yields, material dependencies, and technological lag persist, making this progress a phase transition rather than a race.
China has begun mass-producing domestic immersion DUV lithography machines, capable of supporting 28-nanometer chip manufacturing, and is developing prototype EUV machines, marking real progress in its semiconductor industry amid export restrictions.
Multiple credible sources report that China is now shipping early units of domestically produced immersion DUV lithography systems, which target 28-nanometer nodes and, through multi-patterning, can reach 7- and potentially 5-nanometer nodes. These systems are primarily sourced from Chinese suppliers and evaluated at firms like SMIC and Huawei.
Separately, Reuters has reported that China is developing a prototype EUV lithography machine, the most advanced tool in chipmaking, although it remains in the experimental stage. SMIC has demonstrated 7-nanometer production using older DUV tools, with some reports indicating ongoing development toward 5-nanometer capabilities. Huawei aims to produce over a million high-end AI-accelerator chips this year, indicating a strategic push up the technology stack.
Despite these advances, significant hurdles remain, including low yields—around 20% for 5-nanometer chips compared to 90% in leading fabs—and dependency on imported materials like high-purity photoresist from Japan. Additionally, China’s domestic tools lag behind global leaders by about four generations, and the servicing ecosystem remains dependent on Western suppliers, notably ASML.
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.
Why Incremental Progress in China’s Chip Industry Matters
This progress signals China's strategic shift towards self-reliance in semiconductor manufacturing, which has implications for global supply chains, technological competition, and export controls. While the development of domestic tools is a positive step, the persistent challenges in yields, materials, and technological lag mean China is still years away from achieving fully competitive, high-volume, sub-10-nanometer production.
Understanding that this is a phase transition—requiring gradual accumulation of tacit knowledge through extensive practice—highlights that China's advancements are part of a long-term process rather than a sudden breakthrough. This ongoing evolution will influence global chip markets and technological parity considerations over the next decade.

Background on China’s Semiconductor Development Efforts
Over the past decade, China has invested heavily in domestic chip manufacturing capabilities, aiming to reduce reliance on Western technology and suppliers. Export controls, especially on EUV lithography equipment from companies like ASML, have accelerated efforts to develop indigenous tools. While China has made notable progress in producing older-generation DUV lithography systems, the development of EUV remains in prototype stages, with credible sources estimating a 10-15 year gap compared to global leaders.
Historically, China’s semiconductor industry faced barriers due to technological lag, material dependencies, and servicing challenges. Recent developments, including mass production of 28-nanometer DUV tools and prototype EUV machines, represent significant milestones but are still within the early stages of commercial viability. The industry’s focus is on learning-by-doing, which involves extensive trial, error, and knowledge accumulation over years of operation.
"China’s progress in mass-producing domestic lithography machines marks a real step forward, but the journey from prototype to reliable, high-yield manufacturing remains long."

Remaining Challenges and Technological Gaps
It is still unclear when China will achieve commercial-scale, high-yield production at sub-10-nanometer nodes. The pace of technological lag closing, material independence, and the development of a self-sustaining servicing ecosystem are ongoing issues. The timeline for China to reach parity with global leaders like ASML remains uncertain, with estimates suggesting significant years of further development.

Next Milestones in China’s Semiconductor Journey
China’s immediate focus will be on improving yields and scaling production of 28- and 14-nanometer chips, while advancing prototype EUV tools toward commercial readiness. Monitoring progress in material independence, particularly in high-purity chemicals, and the development of servicing capabilities will be critical. Industry analysts expect incremental improvements over the next 2-5 years, with broader commercial impacts emerging over the next decade.

Key Questions
How significant is China’s progress in domestic lithography?
It marks a meaningful step toward self-reliance, showing China can produce advanced chip manufacturing equipment domestically. However, challenges like low yields and material dependencies mean full competitiveness is still years away.
What are the main technical hurdles China faces?
Key challenges include improving manufacturing yields, reducing reliance on imported materials like high-purity photoresist, and closing the technological gap with global leaders in EUV and other advanced tools.
When might China produce chips at sub-10-nanometer nodes reliably?
Most experts estimate that China could reach commercial production at sub-10-nanometer nodes around 2030, but this depends on overcoming current technical and material hurdles.
What does this mean for the global chip market?
China’s incremental progress may gradually shift the balance of semiconductor manufacturing capabilities, potentially increasing competition and supply chain resilience over the next decade.
