TL;DR
China is making significant progress in developing advanced chipmaking tools, including domestically produced lithography machines. However, challenges like yield, materials, and expertise remain, indicating a phase transition rather than a race. The next steps involve scaling production and overcoming technical hurdles.
China has begun mass production of domestically developed immersion DUV lithography machines, capable of manufacturing chips at 28-nanometer nodes and potentially reaching 7- and 5-nanometer processes, according to multiple credible sources. This marks a significant step in China’s effort to reduce reliance on foreign technology, particularly after export restrictions limited access to EUV equipment. While these developments are real and demonstrate progress, experts caution that the full capability to produce advanced chips reliably and at scale remains a work in progress, with significant technical hurdles still to overcome.
Recent reports confirm that China is now manufacturing domestic immersion DUV lithography systems tied to firms like Huawei and evaluated at SMIC, with the capacity to produce chips at 28-nanometer nodes and multi-patterning techniques indicating potential for 7- and 5-nanometer nodes. A domestic EUV prototype is also reported to be in development, marking progress toward more advanced lithography.
However, the transition from prototype to commercial, high-yield production is not yet complete. SMIC’s reported yield for 5-nanometer chips hovers around 20 percent, compared to the roughly 90 percent yields of leading global fabs using EUV technology. Additionally, China remains dependent on imported high-purity materials, such as photoresist from Japan, which is critical for chip quality and cannot yet be fully domesticated.
Furthermore, Chinese domestic tools lag behind those of industry leader ASML by approximately four generations, with credible forecasts suggesting that sub-10-nanometer commercial manufacturing may not be achievable before around 2030. Maintenance and servicing dependencies on Western suppliers also persist, limiting self-sufficiency in the near term.
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 Progress Is a Phase Transition, Not a Race
This development signifies a phase transition in China’s semiconductor industry—moving from initial prototype capabilities to the complex, iterative process needed for reliable, large-scale manufacturing. While China has made notable strides, the path to self-sufficient, high-yield production at advanced nodes involves accumulating tacit knowledge through extensive, real-world process runs. This underscores that technological mastery in chipmaking is not simply about acquiring machines but about the long-term process of learning and refinement, which cannot be rushed.
For global technology markets and supply chains, this means China’s semiconductor capabilities are evolving, but full independence in advanced manufacturing remains years away. The progress also highlights the importance of understanding the difference between technological development and operational mastery, which is critical for assessing China’s future competitiveness in AI and high-end computing.

China’s Semiconductor Development: From Prototype to Production
Over the past decade, China has aggressively pursued self-sufficiency in chip manufacturing, investing heavily in domestic lithography and fabrication equipment. The country’s progress has often been exaggerated in headlines, but experts emphasize that true manufacturing capability involves not just building machines but mastering complex processes through extensive, iterative learning.
Recent milestones include the production of 28-nanometer DUV lithography systems by Chinese firms, with indications that multi-patterning techniques could enable 7- and 5-nanometer processes. Meanwhile, the development of domestic EUV prototypes signals a strategic push toward more advanced nodes, although industry insiders warn that commercial viability at these scales remains years away.
China’s dependence on imported high-purity materials and maintenance services, primarily from Japan and Western suppliers, further complicates its path to independence. Industry leaders estimate that China’s domestic tools lag behind industry leaders by about four generations, and credible forecasts suggest significant technical and infrastructural gaps must be closed before full commercial deployment at advanced nodes.

Key Questions
How advanced are China’s current chip manufacturing tools?
China has developed domestically produced immersion DUV lithography machines capable of 28-nanometer processes, with prototypes for EUV technology at earlier stages. While progress is notable, these tools lag behind industry leaders like ASML by several generations, and full commercial capability at sub-10-nanometer nodes is still years away.
What are the main hurdles China faces in advancing its chip manufacturing?
Major challenges include improving yield rates, developing high-purity materials domestically, reducing dependence on foreign maintenance services, and closing the technological gap in equipment at the most advanced nodes. Overcoming these hurdles requires extensive process learning, which takes time and large-scale operational experience.
Will China be able to produce chips at the most advanced nodes soon?
Industry forecasts suggest that China may not achieve commercial production at sub-10-nanometer nodes before around 2030, due to technical, material, and infrastructural challenges. Progress is steady but incremental, emphasizing a phase transition rather than a quick race to the finish.
