TL;DR
China has begun mass-producing domestic DUV lithography machines and demonstrated 7-nanometer chip capability. However, challenges like low yields, reliance on foreign materials, and lagging technology still limit commercial-scale, reliable production. The country’s progress is real but incremental, not a sudden breakthrough.
China has begun mass-producing domestic immersion DUV lithography machines capable of manufacturing chips at 28-nanometer nodes, with potential to reach 7- and 5-nanometer processes, according to credible reports. This marks a significant step in China’s effort to break reliance on Western-made equipment, especially after export controls restricted access to EUV technology. The development is part of a broader, deliberate strategy backed by the Chinese government to elevate its semiconductor industry, making this progress noteworthy for global tech competitiveness and supply chain resilience.
Multiple credible sources confirm that China has started mass-producing domestic immersion DUV lithography systems, primarily used for 28-nanometer manufacturing, with some capable of multi-patterning to reach 7-nanometer and potentially 5-nanometer nodes. These systems are largely domestically sourced, representing a strategic achievement after years of technological development. Separately, Reuters reports a domestic EUV prototype is in testing stages, signaling progress toward more advanced lithography.
Meanwhile, Semiconductor Manufacturing International Corporation (SMIC) has demonstrated 7-nanometer chip production using older DUV tools, with yields estimated at around 20 percent—far below the roughly 90 percent yields of leading global fabs using EUV. SMIC is also reportedly working toward 5-nanometer capability, though at a nascent stage. Huawei aims to produce over a million high-end AI chips this year, indicating a clear push to move up the technological stack.
However, experts emphasize that these technological advances are only part of the story. Challenges such as low yield rates, dependence on foreign high-purity materials, and lagging technology generations remain significant hurdles before China can reliably produce advanced chips at scale and profitably.
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 China’s Chip Progress Matters Globally
This progress signals China’s determination to develop a self-sufficient semiconductor industry despite U.S. export controls and restrictions on advanced equipment. Achieving domestic mass production of intermediate and advanced chips could reshape global supply chains, reduce dependence on foreign technology, and intensify competition in the tech sector. However, the road ahead is long, with fundamental issues like low yields, material dependencies, and technological lag still unresolved, meaning China’s capabilities are still in early stages of a long-term transition rather than an immediate breakthrough.

Key Barriers to China’s Semiconductor Self-Reliance
Over the past decade, China has made significant investments in its semiconductor industry, but progress has been constrained by technical and material challenges. Notably, China’s domestic lithography tools lag behind global leaders like ASML by approximately four generations, with credible estimates suggesting full commercial sub-10-nanometer production may not occur before 2030. Additionally, reliance on imported high-purity chemicals such as photoresist from Japan remains a bottleneck, as domestic suppliers are still developing comparable capabilities.
The installed base of advanced DUV tools in China is mostly dependent on Western servicing and maintenance, creating a dependency that undercuts claims of technological independence. The gap between prototype capabilities and large-scale, reliable manufacturing remains substantial, with yield rates and process stability being critical hurdles to overcome.

Unresolved Challenges in Achieving Commercial Scale
While China has demonstrated certain technological milestones, it is not yet clear when these will translate into reliable, high-yield, large-volume production suitable for commercial markets. The pace of improvements in yield, material independence, and process stability remains uncertain, and independent forecasts suggest full sub-10-nanometer commercial capability may not arrive before 2030. The dependency on foreign servicing for existing tools also complicates true self-sufficiency.

Next Steps Toward Advanced, Reliable Chip Production
China’s focus will likely remain on improving yields, reducing reliance on imported materials, and scaling up the production of domestic lithography tools. Monitoring developments in the testing and deployment of the prototype EUV systems and the progress in achieving higher yields at SMIC and Huawei will be critical. The timeline for reaching commercially viable 5- or 3-nanometer chips domestically remains uncertain, but continued investment and incremental progress are expected to shape China’s semiconductor future over the next few years.

Key Questions
How advanced are China’s current chip manufacturing capabilities?
China has begun producing chips at the 28-nanometer level with domestically made DUV lithography machines and has demonstrated 7-nanometer chip production with low yields. However, reliable, high-volume, commercial-scale production at advanced nodes like 5 nanometers remains in development, with significant technical and material challenges to overcome.
What are the main hurdles China faces in becoming self-sufficient in chip manufacturing?
The key challenges include low manufacturing yields, dependence on foreign high-purity materials like photoresist, lagging technology generations in lithography tools, and reliance on Western servicing for existing equipment. These issues slow the transition from prototype to reliable, large-scale production.
When might China achieve commercial production of sub-10 nanometer chips?
Most credible forecasts suggest that China may reach sub-10 nanometer commercial production around 2030, but this depends on overcoming current technical and material dependencies, as well as improving yields and process stability.
How does China’s progress impact global semiconductor markets?
If China can scale reliable, advanced chip manufacturing, it could reduce dependence on Western suppliers, reshape supply chains, and increase competition in the global tech industry. However, significant technical hurdles mean this shift will likely be gradual.
