US-China Semiconductor Export Controls and the Global Chip Equipment Supply Chain Realignment

The United States government's semiconductor export control programme targeting China's advanced chip production capability has entered a new phase of complexity and commercial consequence, with the Bureau of Industry and Security's October 2023 updated rule set expanding the scope of controlled technologies, adding new Chinese entities to the entity list, and extending foreign direct product rule applications that capture exports from non-US suppliers producing goods with controlled US technology or equipment. The commercial impact on the semiconductor equipment industry is substantial and structurally transforming, as the export controls affect not only the direct business that ASML, Applied Materials, Lam Research, and KLA had with Chinese semiconductor manufacturers but also the second-order effects on global supply chain reconfiguration, the competitive response of Chinese semiconductor industry, and the strategic investments in alternative supply chains that US allies in Japan, Netherlands, and South Korea are navigating under US pressure to align their own export control regimes with US restrictions.

The Equipment Export Control Architecture and Its Scope

The core export control architecture restricts the export to China of advanced semiconductor manufacturing equipment for producing chips at or below 14/16nm logic or 128-layer NAND flash nodes, targeting the manufacturing technology that enables production of the most advanced artificial intelligence accelerators, high-performance computing chips, and advanced memory that are assessed to have dual-use military application potential. ASML's extreme ultraviolet lithography systems, which are essential for sub-7nm manufacturing and which ASML has been unable to export to China since 2019, represent the most visible element of the control architecture, but the application of foreign direct product rules to deep ultraviolet lithography systems has extended controls to equipment categories where non-US suppliers, particularly ASML in its DUV product lines, Nikon, and Canon, previously continued to serve Chinese customers without US licence requirements.

The multilateral coordination dimension of the US export control strategy, through which the US has pressed the Netherlands and Japan to align their own export control regimes with US restrictions, has achieved partial success in that both countries have implemented export licensing requirements for specified categories of semiconductor manufacturing equipment, but the precise scope and enforcement approach of the Netherlands and Japanese controls differs from US requirements in ways that create commercial opportunities for equipment in control gaps. Dutch and Japanese equipment makers are navigating the tension between national commercial interests in the Chinese semiconductor equipment market, which was their largest customer segment in some equipment categories, and the US strategic pressure to close control gaps that the US argues undermine the effectiveness of its own restrictions by allowing advanced manufacturing capability to be assembled from non-US controlled components.

Chinese Semiconductor Industry Response and Domestic Development

China's response to semiconductor export controls has combined continued aggressive investment in domestic semiconductor equipment and materials development, strategic inventory accumulation ahead of control tightening announcements, and adaptation of manufacturing processes to utilise equipment that remains accessible within the control architecture to extend the capabilities of the installed base of manufacturing equipment acquired before controls took effect. SMIC's reported production of 7nm-class chips using existing DUV lithography equipment through multi-patterning techniques that extend DUV lithography beyond its conventional design rule application demonstrates that Chinese manufacturers are investing in process engineering workarounds that partially compensate for restricted access to EUV lithography. The gap between DUV multi-patterning capabilities and EUV-enabled process node performance remains significant in terms of yield, cycle time, and cost per wafer, but Chinese manufacturers are demonstrating that the control architecture has not eliminated advanced chip production capability, only constrained and complicated it.

China's domestic semiconductor equipment industry, anchored by companies including NAURA Technology Group, Advanced Micro-Fabrication Equipment (AMEC), and North Micro-Electronics, is receiving massive government investment to accelerate the development of domestic alternatives to controlled imported equipment across etch, deposition, cleaning, and measurement categories. The technical gap between current Chinese domestic equipment and best-in-class equipment from ASML, Applied Materials, and Lam Research remains substantial in the most demanding process steps, and the timelines for closing that gap to the level required for high-volume production of advanced chips are measured in years to decades rather than months. The commercial consequence for the global semiconductor equipment industry is bifurcation: an increasingly self-sufficient Chinese domestic equipment market developing in parallel with the global supply chain centred on US, Dutch, and Japanese equipment vendors serving non-Chinese advanced manufacturing customers.

Semiconductor Equipment Vendor Commercial Adaptation

Applied Materials, Lam Research, and KLA, the three largest US semiconductor equipment companies by revenue, have each reported material revenue impacts from China export control restrictions, with China having been their largest revenue market in the period immediately preceding the most significant control tightening. The commercial adaptation strategies vary by company and equipment portfolio: companies with mature product lines facing the most direct export restrictions have accelerated growth investment in non-China markets including Taiwan, South Korea, Japan, and the emerging US semiconductor manufacturing capacity being built under CHIPS Act incentives; while equipment categories with less direct export control exposure continue to generate revenue from the significant volume of Chinese semiconductor manufacturing capacity operating below the control node thresholds. The long-term revenue exposure from China market access loss is partially offset by the global semiconductor capacity buildout being stimulated by the geopolitical semiconductor supply chain diversification investment in US, European, and Asian allied manufacturing, creating equipment demand outside China that partially compensates for China revenue loss over time.

ASML is the company most structurally affected by semiconductor export controls because its EUV lithography monopoly positions it as the single-point of control for the most advanced semiconductor manufacturing technology, making it the central focus of both US export control policy and Chinese domestic development effort. ASML's China DUV revenue represents a significant share of its total systems revenue, and the progressive tightening of DUV export licences to China is a material and ongoing commercial impact that ASML is managing through accelerated capacity commitment in Taiwan, Korea, and Intel's US operations and through pricing discipline in markets where it retains access. ASML's EUV high-NA system development, which provides the next-generation manufacturing technology for below-2nm logic nodes and which will be inaccessible to Chinese manufacturers regardless of diplomatic resolution of current control tensions, represents the technology advantage that makes ASML's long-term competitive position independent of China market access.

Supply Chain Reconfiguration and Allied Manufacturing Investment

The geopolitical semiconductor supply chain reconfiguration stimulated by export control policy and industrial strategy programmes, including the US CHIPS and Science Act, the EU Chips Act, and Japan's semiconductor manufacturing subsidy programme, is creating a new wave of semiconductor manufacturing capacity in markets that were previously underinvested relative to Taiwan, South Korea, and China concentration. TSMC's Arizona fabs, Samsung's Texas expansion, Intel's Ohio and Germany facility development, and TSMC's Japan facility with Sony and Denso investment represent the leading edge of a supply chain geographic rebalancing that will add significant semiconductor manufacturing capacity in US-aligned markets over the 2024 to 2030 period. The semiconductor equipment demand generated by this manufacturing buildout is predominantly served by the same US, Dutch, and Japanese equipment vendors whose China revenue is under pressure, creating a partial revenue replacement dynamic that moderates but does not fully offset the China access loss in the near term.

The materials and specialty chemicals supply chain for semiconductor manufacturing, encompassing photoresists, process gases, chemical mechanical planarisation slurries, and specialty solvents, is subject to its own export control dynamics as Japan and the Netherlands have applied restrictions to specific advanced semiconductor materials in coordination with US policy. JSR, Shin-Etsu Chemical, and TOK supply advanced photoresists for EUV and ArF immersion lithography that are essential for the most advanced semiconductor manufacturing nodes and that China's domestic materials industry has not developed alternatives for at equivalent performance levels. The specialty materials supply chain restrictions, combined with equipment controls, create a compound barrier to Chinese domestic advanced semiconductor manufacturing scale-up that is more difficult to work around than equipment restrictions alone, as materials innovation cycles are long and the performance requirements are unforgiving at advanced manufacturing nodes.
