Semiconductor Research Expansion - April 2026 Update

Completed: Expanded semiconductor research section with two parallel workstreams on US fab expansion and supply chain materials/EDA.

New Sections Added

1. US Domestic Fab Expansion (us-fab-expansion/)

  • Landing Page: _index.md — Master fab tracker with 15 major projects, CHIPS Act analysis, strategic insights
  • Profile: TSMC Arizona (tsmc-arizona.md) — Fab 21 Phases 1–3; 4nm in production, 3nm equipment install Q3 2026, 2nm planned 2029+
  • Analysis: Tesla Dojo (tesla-dojo-clarification.md) — Clarifies Tesla is fabless; D1 chips made by TSMC at 7nm; no dedicated Tesla fab planned

2. Materials & Chemicals (materials/)

  • Landing Page: _index.md — Materials supply chain overview; strategic Japan concentration risk analysis
  • Profile: JSR Corporation (jsr.md) — Photoresist leader; government-backed acquisition by Japan IC Manuf. Corp. (2023); market dominance

3. Chip Design — EDA & IP (chip-design/)

  • Landing Page: _index.md — EDA duopoly (Synopsys 35–40%, Cadence 30–35%); Arm IP dominance; export control implications
  • Profile: Synopsys (synopsys.md) — #1 EDA vendor; ANSYS acquisition completed July 2025 ($35B); CEO Sassine Ghazi

Key Research Findings

Critical Insights

  1. US Fab Independence Risk: Only TSMC Arizona (4nm) currently in production. Intel Ohio delayed to 2030–2031. Samsung Taylor customer-constrained. Single-source TSMC dependency persists.

  2. Materials Bottleneck: Japan controls 75% of photoresists, 90% of EUV mask blanks. Disruption in Japan would halt all US fabs in 2–4 weeks. Strategic vulnerability overlooked in CHIPS Act planning.

  3. CHIPS Act Reality: PMT (preliminary terms) are not binding. Multiple awards reduced after negotiation (Samsung $6.4B → $4.7B). Disbursements lag behind binding awards by quarters.

  4. EDA Export Controls: Synopsys/Cadence tools restricted to China. Estimated 18–24 month delay in Chinese chip design innovation. Strategic lever comparable to fab equipment controls.

  5. Synopsys-ANSYS Integration: First integrated EDA+simulation platform (completed July 2025). Consolidates design software with physics simulation tools.

Index Updates:

  • Update main semiconductors/_index.md with links to new us-fab-expansion/, materials/, chip-design/ sections
  • Update fabrication-equipment/_index.md with ASML, Applied Materials, Tokyo Electron profiles

Review & Maintenance Schedule

  • us-fab-expansion: 90-day review cycle (fab timelines slip frequently)
  • materials: 180-day review cycle (slower-moving supply chain)
  • chip-design: 180-day review cycle (EDA/IP markets stable, but M&A and export controls require monitoring)

Date Completed: April 24, 2026
Research Area: semiconductors/
Next Review: July 24, 2026 (90-day cadence for fab section)
