China’s Semiconductor Strategy: Deepening Mature-Node Capacity and Rare-Earth Resource Weaponization

China’s semiconductor push remains resolutely focused on scaling mature-node foundries where technological barriers are lower, enabling volume-driven competitiveness. The National Integrated Circuit Industry Investment Fund continues to inject billions of yuan into expanding domestic fabs and fostering R&D in lithography, inspection, and metrology tools—critical for narrowing gaps with Western technology.

Significantly, China’s recent rare-earth export embargo on ASML, the Dutch producer of indispensable EUV lithography systems, marks a new escalation in resource diplomacy. By leveraging its near-monopoly on rare-earth elements—vital not only for EUV machines but also for permanent magnets and specialty semiconductor materials—China is weaponizing natural resource dominance to constrain the supply chain of the world’s most advanced chipmakers.

This embargo has sent shockwaves through global semiconductor supply chains, highlighting China’s strategic integration of semiconductor ambitions with resource security and industrial policy under the “New National Fortune” vision. This vision explicitly aims to elevate China’s technological sovereignty and AI capabilities by controlling critical inputs and fostering indigenous innovation ecosystems.

U.S. and Allied Countermeasures: Intensified Export Controls and Localization Drives

In response, the United States and allied governments have significantly expanded export controls and localization incentives, aiming to stymie China’s semiconductor progress and reduce dependencies:

• The U.S. Trade Representative broadened Section 301 investigations to include not just China but also key semiconductor hubs like Taiwan and South Korea, signaling heightened scrutiny on technology flows and investment ties.

• The continued blocking of Nvidia’s H200 AI chip shipments to China has forced a notable reallocation of wafer capacity—dubbed the “Great Wafer Cannibalization”—where foundries prioritize AI and high-performance computing (HPC) chip production at the expense of legacy products.

• This shift has had tangible operational impacts, with TSMC suspending collaboration with Chinese AI startup Biren, underscoring the chilling effect of export controls on cross-border semiconductor innovation and partnerships.

• Localization policies remain robust:

  • The U.S. CHIPS and Science Act channels massive subsidies toward domestic fab expansion and advanced R&D.
  • Japan’s Economic Security & Semiconductor Revitalization Strategy aggressively incentivizes fab growth and innovation collaboration.
  • The EU Semiconductor Act aims to build regional supply chain resilience and semiconductor self-sufficiency.

AI-Driven Packaging Bottlenecks and the “Great Wafer Cannibalization”

The surge in AI chip demand has exposed critical bottlenecks in advanced packaging technologies, particularly Chip-on-Wafer-on-Substrate (CoWoS) solutions. Industry reports reveal that 80–90% of TSMC’s advanced packaging capacity remains centralized in Taiwan, creating capacity constraints that limit scaling agility.

This packaging bottleneck compounds the “Great Wafer Cannibalization” effect, wherein foundries prioritize advanced-node wafers for AI and HPC chips, diverting capacity from legacy and lower-margin semiconductor products. While this dynamic drives innovation and revenue growth in AI segments, it introduces volatility and complexity in supply chain management for other semiconductor applications.

TSMC’s heavy 2026 capex focus on both advanced nodes and packaging reflects a strategic response to these pressures, aiming to alleviate bottlenecks and sustain long-term leadership in AI semiconductor manufacturing.
