US, Japanese Semiconductor Equipment Conceals Chinese Raw Material Dependence - 조선일보

US and Japan retain dominant positions in lithography and etching equipment, yet a BOM-level dissection reveals a structural dependency: China still commands over 60% of global capacity in upstream purification of high-purity silicon, gallium-germanium substrates, rare-earth permanent magnets, and specialty electronic gases. This is not a mirror-image of chokepoint leverage—it is a structural lock-in born of division of labor. Equipment makers can swap suppliers; material purity specs, process windows, and 3-5-year qualification cycles cannot be shortcut. Compliance exposure: if Washington folds material provenance into its export-control regime, procurement costs at Tokyo Electron and Lam Research could rise 15-25% within 18 months, while smaller material suppliers face disproportionate fixed compliance costs. Strategic game: Washington and Tokyo will likely replicate the CHIPS Act playbook—subsidizing rare-earth and germanium mining in Australia and Canada. But the mine-to-electronic-grade conversion timeline far outpaces equipment iteration cycles. Over the next 12-24 months, expect: intensified price volatility in specialty gases, a joint material-whitelist certification framework, and Beijing extending its export-control list downstream as a counter-hedge. Bottom line: equipment decoupling is political narrative; material interdependence is physical reality. Whoever owns the purification know-how holds the real bargaining power.
