TSMC may be roughly a decade ahead of China’s leading manufacturers in some aspects of advanced, high-volume chip production—particularly EUV-enabled process integration and the ability to manufacture leading-edge chips efficiently at scale. There is no precise, independently established measure showing that TSMC is exactly 10 years ahead of all Chinese chip development. The oft-repeated estimate came from ASML CEO Christophe Fouquet, who described Chinese companies as about 10–15 years behind leading Western semiconductor companies; it was an estimate about China’s capabilities, not a TSMC-versus-China benchmark or a forecast of when China will catch up. Tom’s Hardware reported Fouquet’s remarks.
What does “10 years ahead” mean?
“Chip development” can mean designing a processor, manufacturing its silicon, packaging several dies together, or producing chips reliably and economically in large quantities. These are related capabilities, but they do not advance at the same pace. The 10–15-year statement is principally about advanced chipmaking capability—not a claim that Chinese firms are a decade behind in every kind of chip design or semiconductor technology.
- Process technology: how transistors and interconnects are formed, including their density and power-performance characteristics.
- Manufacturing execution: yield, defect control, repeatability, wafer throughput and cost.
- Equipment and software: lithography, metrology, materials, manufacturing tools, electronic design automation (EDA) and intellectual property.
- Packaging and systems: chiplets, stacked dies, memory integration, interconnects and software that help determine real-world computing performance.
- Scale and ecosystem: qualified customers, skilled suppliers, process-learning data and the capacity to make products consistently.
Likewise, “China” is not one manufacturer. It includes foundries such as SMIC, chip designers such as Huawei, equipment companies, research institutions and a large domestic market. TSMC is a single, highly focused foundry. A comparison must specify whether it means TSMC versus SMIC, TSMC versus China’s best demonstrated manufacturing, or Taiwan’s advanced-node ecosystem versus China’s broader semiconductor sector.
What is the evidence for the decade estimate?
ASML CEO Christophe Fouquet’s estimate is the clearest origin of the 10–15-year framing. He was describing Chinese companies’ distance from leading Western semiconductor capabilities after China was denied access to EUV lithography. It was not an independently measured industry standard, and “behind by 10–15 years” describes a judgment about the present gap; it does not establish that China will take exactly that long to catch up. A U.S. congressional witness also discussed the estimate in written testimony.

To judge such a claim, look beyond a chip’s advertised node. Relevant evidence includes density, power and performance, yield, throughput, cost, equipment access, packaging, customer adoption and the time required to reach volume production. A successful chip or process demonstration is meaningful, but by itself does not show that a manufacturer can make the product repeatedly, economically and at commercial scale.
Where TSMC stands at the leading edge
TSMC’s 2025 annual-report materials say its N2 technology entered volume production in the second half of 2025. The company also said its A16 (16-angstrom) technology was on track for risk production in 2026. Risk production is an engineering and customer-validation milestone, not the same thing as volume production or proof of commercial yields. These are company disclosures, not a like-for-like independent comparison with Chinese production. See TSMC’s 2025 annual report and its 2025 Form 20-F.
TSMC’s advantage is not just its process-generation label. It has to qualify processes for customers, learn from production, control defects and integrate leading-edge logic with advanced packaging. Its annual report describes technologies including CoWoS and SoIC for combining or stacking chips. For demanding products, that integration and manufacturing experience can matter as much as a nominal node number.
Rank #2
Labels such as “2 nm,” “3 nm,” “5 nm” and “7 nm” are process-generation names, not perfectly standardized measurements shared across companies. Two chips bearing similar node labels need not have the same transistor density, power use, yield or manufacturing cost. The label alone cannot establish technical or commercial equivalence.

What China has achieved—and what remains difficult
China has made real progress at the frontier. SMIC has produced 7 nm-class chips without EUV, and Huawei and SMIC have pursued 5 nm-class production using non-EUV methods. That matters: it disproves the idea that China simply cannot make advanced-node-class chips. But the existence of a process or product does not, without comparable public evidence, establish TSMC-level yield, throughput, cost or volume. CSIS examines the distinction in its analyses of DeepSeek and advanced-chip production and Huawei, export controls and the AI race.
China is also localizing semiconductor equipment and suppliers, with stronger progress in some mature-node segments than at the leading edge. Domestic production at mature nodes can be economically and strategically important even when it does not match the frontier. China’s equipment efforts and the unevenness of localization are discussed by CSIS. That analysis does not make every announced target a current manufacturing capability.
The distinction to keep in view is technical demonstration versus competitive production. A chip may work but still be costly, slow to produce or difficult to manufacture consistently. Publicly available evidence does not support treating every Chinese advanced-chip effort as either a failure or an equivalent to TSMC’s high-volume frontier production.
Why EUV matters—but is not the whole story
Extreme ultraviolet (EUV) lithography uses short-wavelength light to pattern very small features. ASML is the sole commercial supplier of EUV lithography systems, and export restrictions have kept China from buying them. EUV can reduce the need for repeated patterning steps used with deep ultraviolet (DUV) equipment at advanced nodes, making the production flow less complex than a DUV-only alternative. ASML describes its technology and supply-chain context in its 2025 annual-report CEO message.

DUV multipatterning can produce some advanced-node-class chips, as China’s achievements illustrate. But using more patterning steps increases process complexity and can impose disadvantages in cost, throughput and yield. Those disadvantages make it harder to compete at scale; they do not make advanced production impossible.
Rank #4
Nor would a domestic EUV prototype, on its own, erase the gap. A production-ready system must deliver reliability, overlay accuracy, throughput and uptime, and work with the rest of the fab’s tools, materials and process controls. Building the machine is distinct from building the supplier network, process knowledge and years of manufacturing data that support a high-yield foundry. ASML’s account of EUV’s development emphasizes that broader ecosystem as well as the tool itself.
How export controls affect the gap
Restrictions on EUV directly limit China’s access to the leading commercial lithography platform. Other controls also cover parts of the semiconductor-equipment chain, advanced computing chips, EDA software and technical support. TSMC’s Form 20-F discusses export-control risks to its business and supply chain; the filing is a company disclosure, not an independent measurement of the controls’ effect on China.
Controls can constrain near-term access while giving Chinese firms and policymakers a stronger reason to replace foreign tools and suppliers. Localization may accelerate in areas where domestic substitutes are feasible, while highly specialized leading-edge equipment remains harder to reproduce. The effect is therefore mixed: controls can widen the immediate frontier gap and encourage long-term domestic development at the same time. They are an important factor, not the sole explanation for TSMC’s position, which also reflects years of process development, supplier relationships, customer collaboration, engineering talent and production learning.

Why a process gap is not the same as an AI or design gap
Manufacturing node is only one input to a chip’s usefulness. Architecture, memory bandwidth, packaging, interconnects, software and system design can all affect performance. Advanced packaging can combine multiple dies into a system that suits a workload even when each die is not made on the most advanced process. CSIS discusses the role of architecture and system-level factors in its analysis of Huawei’s chip strategy and the wider chip race.
That means China can make strategically valuable chips and improve system performance without first matching TSMC node for node. It does not mean packaging or architecture makes manufacturing constraints disappear: cost, energy use, supply availability and production volume still matter. A claim about TSMC’s manufacturing lead should not be converted into a blanket ranking of all Chinese chip design or AI capability.
Three plausible paths for the gap
The leading-edge gap persists or widens
This becomes more likely if China remains without commercial EUV access, domestic alternatives for lithography and other critical tools mature slowly, and TSMC continues advancing its process and packaging capabilities. DUV-based production could remain possible while being less efficient or harder to scale economically.
China narrows the practical gap without matching TSMC’s nodes
Better yields from DUV multipatterning, improved domestic EDA and equipment, larger production runs, chiplets, packaging advances and system-level optimization could make Chinese products more capable and useful. State support and domestic demand can help sustain those efforts. China could become more strategically competitive even if its leading manufacturing process remains behind TSMC’s.

A reliable domestic lithography platform, a major process or packaging innovation, or effective substitution across a toolchain could change the trajectory. A prototype or public target would not by itself establish that the breakthrough is ready for high-volume manufacturing; evidence on reliability, throughput, yield and cost would matter. Chinese semiconductor executives have also described fragmentation in the domestic equipment sector as a weakness in efforts to replace ASML, as reported by Tom’s Hardware.
How to read the claim
The most defensible interpretation is that TSMC may be roughly a decade ahead of China in some dimensions of leading-edge semiconductor manufacturing, especially EUV-enabled process integration and economical production at scale. The evidence does not establish an exact 10-year lead across all Chinese chip development, nor does Fouquet’s estimate say how long China will take to catch up. Any serious comparison should name the companies or ecosystems involved and distinguish process technology from yield, volume, packaging, design and commercial competitiveness.
