TL;DR
China has begun mass-producing domestic DUV lithography machines and prototypes for EUV tools, marking real progress. However, significant gaps remain in yield, materials, and expertise. The development reflects a phase transition, not a race, requiring years of accumulated learning.
China has begun mass-producing domestic immersion DUV lithography machines and is developing prototype EUV tools, marking significant progress in its semiconductor self-sufficiency efforts. This development is crucial as it demonstrates China’s move up the chip manufacturing stack, despite ongoing technical challenges. The progress matters because it indicates a shift from reliance on foreign technology toward domestic capabilities, impacting global supply chains and technological competition.
Multiple credible sources confirm that China has started manufacturing and deploying domestic immersion DUV lithography systems, capable of producing chips at 28-nanometer nodes and potentially reaching 7- and 5-nanometer nodes through multi-patterning. These systems are primarily sourced from Chinese firms tied to Huawei and evaluated at SMIC, China’s leading foundry. Additionally, Reuters reports the existence of a prototype domestic EUV machine, which is a significant milestone given EUV’s complexity and its previous reliance on foreign suppliers.
Despite these advances, China’s current capabilities are still limited by several factors. Yield rates for 7-nanometer chips produced with domestically made DUV tools are estimated at around 20 percent, compared to 90 percent in leading global fabs using EUV. China remains heavily dependent on imported high-purity photoresist from Japan, which is critical for chip quality. Moreover, the domestic tools lag behind global leaders like ASML by about four generations, and experts forecast commercial sub-10-nanometer production domestically may not occur before 2030. The installed base of DUV tools also requires ongoing foreign servicing, as China lacks the in-house expertise to maintain high-end equipment at scale.
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 Semiconductor Progress Matters Globally
This progress signifies a critical phase in China’s efforts to develop an independent semiconductor supply chain, reducing reliance on Western and Japanese technology. While the current capabilities are still limited and not yet commercially competitive at the most advanced nodes, the move indicates a long-term strategic shift. It also underscores the importance of the learning process in complex manufacturing, which cannot be bypassed by simply acquiring equipment or technology. The development could reshape global supply dynamics and accelerate China’s technological ambitions, but significant technical and infrastructural hurdles remain before achieving full self-sufficiency.

Background of China’s Semiconductor Development Efforts
Over the past decade, China has prioritized semiconductor independence amid export restrictions and geopolitical tensions. Early efforts focused on acquiring foreign technology, but recent years have seen a push toward domestic innovation, especially in lithography, a key step in chipmaking. Progress has been incremental, with China successfully producing mature nodes and developing prototypes for advanced tools like EUV. However, the industry recognizes that mastering the tacit knowledge—learning-by-doing—remains the biggest challenge, as it involves years of experience in process optimization, materials handling, and equipment maintenance.
Global leaders like ASML have set the standard with their EUV systems, which are not only technologically complex but also require an extensive ecosystem of service, materials, and expertise. China’s efforts are now focused on closing these gaps, but experts emphasize that this is a gradual process akin to crossing a phase transition rather than a sprint race.
"The real challenge isn't just building machines; it's the years of accumulated tacit knowledge needed to run them at scale, reliably and profitably."

Unresolved Challenges in China’s Semiconductor Progress
It is still unclear when China will achieve commercial-scale, sub-10-nanometer production with domestically developed tools. The exact timeline for closing the yield gap, securing high-purity materials, and establishing independent maintenance capabilities remains uncertain. Moreover, the extent to which China can accelerate learning and overcome these technical hurdles in the coming years is still under assessment, with industry experts cautious about predicting rapid breakthroughs.

Next Steps in China’s Semiconductor Development Roadmap
China is expected to continue ramping up production of domestic DUV systems, aiming to improve yields and material independence. Focus will likely shift toward developing in-house maintenance and process expertise, reducing reliance on foreign servicing. The industry will monitor progress on prototype EUV tools, with key milestones including achieving commercial sub-10-nanometer capability and scaling high-volume manufacturing. International cooperation and supply chain adjustments will also influence the pace of China’s semiconductor self-sufficiency journey.

Key Questions
How advanced are China’s domestic lithography machines?
China’s domestic immersion DUV lithography machines are capable of producing chips at 28-nanometer nodes and are believed to be capable of reaching 7- and 5-nanometer nodes through multi-patterning. A prototype EUV machine has also been reported, marking a significant step forward.
What are the main obstacles China faces in advancing its chipmaking?
The primary challenges include low yield rates (around 20% for advanced nodes), dependence on imported high-purity materials, lagging behind global leaders in equipment generations, and the need for ongoing foreign servicing and expertise.
When might China achieve full commercial sub-10-nanometer production?
Most experts estimate that China will not reach commercial sub-10-nanometer capability with domestically produced tools before around 2030, due to the need for extensive process learning and infrastructure development.
Why is the learning process so important in semiconductor manufacturing?
Because mastering the tacit knowledge—such as process optimization, materials handling, and equipment maintenance—is essential for reliable, high-yield, large-scale production. This knowledge cannot be simply copied or bought; it must be accumulated through years of experience.
