Semiconductors

The most complex supply chain ever built — thousands of steps across a dozen countries to turn sand and a few critical elements into the logic and memory everything else runs on.

The stack

Where value & control concentrate

✏️

Design (EDA & IP)

Nvidia, AMD, Apple, Qualcomm design; Synopsys & Cadence own the EDA tools; Arm licenses the cores. US/UK dominated.

🏭

Foundry

TSMC makes ~90% of leading-edge logic, with Samsung and Intel trailing. Taiwan is the single point of concentration.

🔬

Equipment

ASML (NL) is the sole maker of EUV lithography. Applied Materials, Lam, Tokyo Electron, KLA round out deposition/etch/metrology.

🧪

Materials

Wafers (Shin-Etsu, SUMCO), photoresists (JSR, Tokyo Ohka), gases, and the critical elements below. Japan-heavy.

📦

Packaging (OSAT)

Advanced packaging — CoWoS, chiplets — is now a bottleneck of its own. TSMC, ASE, Amkor lead.

Power & RF (compound)

GaN and SiC for power electronics and RF; gallium & silicon-carbide supply is China-concentrated.

The chokepoints

  • EUV lithography — ASML is the only supplier on Earth; no leading-edge chip exists without it.
  • Leading-edge foundry — TSMC's Taiwan fabs are a geopolitical single point of failure.
  • Gallium & germanium — China controls ~95% / ~68% of supply and has imposed export controls.
  • Photoresists & wafers — a few Japanese firms dominate.

Why the materials matter

Silicon is the substrate, but the leverage sits in the minor metals: gallium and germanium for high-frequency and power devices, indium for displays and transceivers, plus the ultrapure gases and rare earths used in polishing and deposition. These are small markets with outsized strategic weight — exactly the supply chains mapped in the minerals engine.
