TL;DR
China has begun mass-producing domestic immersion DUV lithography machines and is developing advanced chips at the 7- and 5-nanometer scale. While progress is real, challenges like yield, materials, and technological lag persist, making this a phase transition rather than a race.
China has started 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 multiple credible sources. This marks a significant step in China’s effort to develop independent semiconductor manufacturing capabilities, a goal driven by export controls and technological ambitions.
Recent reports confirm that China has begun mass-producing domestic immersion DUV lithography systems, primarily used for 28-nanometer chip production, with some systems capable of multi-patterning to achieve smaller nodes like 7 nanometers. These tools are mostly domestically sourced, and prototypes of advanced EUV machines are also under development, with some at the prototype stage, according to Reuters.
Meanwhile, Semiconductor Manufacturing International Corporation (SMIC) has demonstrated 7-nanometer chip production using older DUV tools with multi-patterning, and is reportedly working toward 5-nanometer capabilities. Huawei plans to produce over a million high-end AI chips this year, indicating a clear push up the technology stack. However, despite these advancements, significant hurdles remain, including yield rates, material dependencies, and technological lag behind global leaders like 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.
Implications of China’s Semiconductor Progress
This progress demonstrates China’s commitment to achieving technological independence in chip manufacturing, which is critical for both economic security and national strategic interests. While the development of domestic tools and chip capabilities is genuine, the challenges of scaling, yield, and materials mean that full commercial viability at the most advanced nodes is still years away. This ongoing effort influences global supply chains, US-China tech policy, and the future of AI and electronics industries worldwide.

China’s Semiconductor Ambitions and Challenges
Over the past decade, China has prioritized developing its semiconductor industry as part of broader technological self-sufficiency goals. Initial efforts faced setbacks due to export restrictions, particularly on EUV lithography equipment from the Netherlands and Japan. Recent progress includes the production of domestically sourced DUV lithography machines, with some capable of multi-patterning at 7 nanometers, and prototypes of EUV systems. Experts note that China remains at least a decade behind leading-edge technology, with credible forecasts suggesting commercial sub-10 nanometer production may not be feasible before 2030.
Furthermore, China’s reliance on imported high-purity materials, especially photoresist from Japan, remains a bottleneck. The installed base of advanced DUV tools is heavily dependent on Western servicing, creating vulnerabilities in maintenance and operations. Despite these hurdles, the country’s deliberate, state-backed approach indicates a long-term strategy focused on incremental mastery rather than quick wins.
"Progress in China’s chipmaking is real but layered with significant technical and operational challenges that will take years to overcome."

Remaining Challenges and Unknowns in China’s Semiconductor Roadmap
It is still unclear when China will achieve reliable, high-yield production at sub-10 nanometers on a commercial scale. The extent to which domestic materials, especially high-purity photoresist, can be replaced remains uncertain. Additionally, the timeline for fully indigenous EUV systems reaching mass production is still uncertain, with expert forecasts suggesting this may not occur before 2030. The impact of ongoing US export restrictions on China’s progress also remains a key unknown.

Next Steps in China’s Semiconductor Development
China is expected to continue ramping up production of domestically made DUV lithography tools, aiming to improve yield and reliability. Parallel efforts will focus on developing and scaling EUV prototypes, along with sourcing alternative materials to reduce dependency on imports. Monitoring SMIC’s yield improvements and Huawei’s chip production volumes will provide indicators of progress. International policy developments and export controls will also influence the pace of China’s technological breakthroughs.

Key Questions
How advanced are China’s current chip manufacturing capabilities?
China has begun mass-producing 28-nanometer chips using domestically produced DUV lithography machines and has demonstrated 7-nanometer production with multi-patterning. However, these are not yet at the level of global leaders in yield, reliability, or complexity for commercial-scale production.
What are the main obstacles China faces in advancing its chip technology?
Major challenges include low yield rates (around 20% compared to 90% in leading fabs), dependency on imported high-purity materials like photoresist, technological lag behind the most advanced equipment, and reliance on Western servicing for maintenance of existing tools.
When might China achieve commercial production of sub-10 nanometer chips?
Experts estimate that China could reach sub-10 nanometer production at a commercial scale around 2030, but this depends on overcoming yield, materials, and equipment development hurdles.
Why is China’s progress significant despite the challenges?
It indicates a deliberate, long-term strategy to build independent semiconductor manufacturing capabilities, which could reshape global supply chains and reduce reliance on Western technology, even if full mastery is still years away.
