TL;DR
China has begun mass-producing some advanced chip manufacturing equipment domestically, marking progress in its AI chip ambitions. However, significant technical and supply chain challenges remain before these capabilities can be reliably scaled for commercial use. The true barrier is the accumulated tacit knowledge needed for large-scale, high-yield production.
China has begun mass-producing domestic immersion deep ultraviolet (DUV) lithography machines and is prototyping extreme ultraviolet (EUV) tools, marking tangible progress in its efforts to develop independent chip manufacturing capabilities, despite export restrictions. This progress is significant because it indicates China’s move up the manufacturing stack, but experts caution that substantial hurdles remain before these tools can produce high-yield, commercially viable advanced chips at scale.
Credible sources report that China is now manufacturing domestically developed immersion DUV lithography machines capable of producing chips at the 28-nanometer node, with some capacity approaching 7-nanometer and potentially 5-nanometer through multi-patterning techniques. These systems are primarily used by firms like SMIC and Huawei, and most components are sourced domestically, a notable achievement given export restrictions.
Separately, Reuters has reported that China is developing an EUV lithography machine at the prototype stage, a significant step given that EUV is crucial for cutting-edge chip nodes. However, these are still early-stage prototypes, not yet capable of commercial-scale production.
While these developments mark progress, experts emphasize that the core challenge remains: achieving high yields and reliable, large-scale manufacturing. Currently, SMIC produces 7-nanometer chips with yields around 20%, far below the approximately 90% yields of leading global fabs using EUV technology. This yield gap is a fundamental barrier to commercial viability and long-term competitiveness.
Further challenges include dependence on imported high-purity materials, especially photoresist chemicals from Japan, and the lag in domestic equipment compared to international leaders like ASML. Chinese tools are estimated to be roughly four generations behind, with credible forecasts suggesting domestically produced equipment may not reach sub-10 nanometer nodes before around 2030. Additionally, the installed base of existing equipment relies heavily on Western servicing and maintenance, which China cannot fully control.
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 in Domestic Chip Tools Is Not Enough
This development is a critical step in China’s broader goal of achieving technological independence in semiconductor manufacturing, which is vital for its ambitions in AI and advanced computing. However, the progress must be viewed in context: the real barrier is learning-by-doing. The ability to produce high-yield, reliable, and scalable chips depends on accumulating tacit knowledge through years of operational experience, not just building machines.
Without overcoming yield and materials challenges, China’s efforts risk remaining at the prototype stage, unable to compete with established global leaders in high-end chip production. This underscores that the so-called 'wall' is not just about equipment but about mastering the complex, incremental process knowledge essential for commercial success.

China’s Chip Manufacturing Ambitions and the Learning Wall
Over the past decade, China has invested heavily in developing its semiconductor industry, aiming to reduce reliance on foreign technology and supply chains. While recent reports highlight advances in domestic lithography equipment, experts have consistently emphasized that the real challenge lies in closing the gap in process maturity, yields, and materials.
Historically, China’s chip industry has relied on imported equipment, especially from Dutch firm ASML, which dominates EUV lithography. Export restrictions and technological embargoes have spurred efforts to develop domestic alternatives, but these are still in early stages. The industry recognizes that achieving full commercial capability requires more than just new machines; it demands years of operational experience, process optimization, and supply chain resilience.
Previous attempts at scaling advanced nodes have faced setbacks, often due to yield issues and material shortages. The current progress indicates a strategic shift, but experts warn that the path to truly independent, high-volume manufacturing remains long and complex.
"Progress in domestic lithography tools is real, but the gap in yields, materials, and process knowledge remains a formidable barrier to true independence."

Unresolved Challenges in Achieving Commercial-Scale Production
It is still unclear when China will be able to consistently produce high-yield, sub-10 nanometer chips at scale, given current yield levels, materials dependency, and the lag in domestic equipment. Experts estimate that reaching this milestone may not occur before 2030, but precise timelines remain uncertain due to the complex nature of process learning and supply chain development.

Next Steps in China’s Semiconductor Development Roadmap
China will likely continue refining its domestic lithography machines, aiming to improve yields and material purity. Parallel efforts will focus on developing the supply chain for critical materials and establishing a self-sustaining maintenance ecosystem. Industry watchers will monitor progress toward commercial-scale, high-yield production, especially at the 7- and 5-nanometer nodes, over the next few years.
Additionally, government policies and international trade dynamics will influence the pace and scope of China’s semiconductor ambitions, shaping whether these technological advancements translate into global market competitiveness.

Key Questions
What is the significance of China developing domestic lithography machines?
Developing domestic lithography machines reduces reliance on foreign technology, which is crucial for strategic independence in chip manufacturing, especially amid export controls and sanctions.
Why is yield such a critical issue in chip manufacturing?
Yield determines how many chips produced are functional and usable. Low yields mean high waste, high costs, and limited scalability, making it a key barrier to commercial viability.
When might China achieve commercial-scale production of advanced chips?
Most credible forecasts suggest that China may reach sub-10 nanometer commercial production around 2030, but this depends on overcoming technical and supply chain challenges.
How does supply chain dependency affect China’s chip ambitions?
Dependence on imported high-purity materials and maintenance services limits China’s control over its manufacturing process, delaying full independence and scaling efforts.
