Inside Soitec, the French tech company powering the global semiconductor industry - Euronews.com

Soitec's Smart Cut process is the invisible chokepoint in the global RF front-end and automotive power chain. When 5G base stations and 800V EV platforms scale simultaneously, SOI substrate yield and thickness uniformity dictate the PDK iteration cadence at downstream foundries — a bottleneck most industry narratives overlook. On compliance, the EU Chips Act elevates Soitec to strategic-supplier status, subsidizing French capex but subjecting capacity allocation to Brussels' security-review logic. Tightened export controls toward mainland China would strip 15-20% of revenue exposure, and Shin-Etsu/SUMCO will accelerate SOI line expansion to fill the vacuum. Competitively, GlobalWafers (Taiwan, China) is eroding mid-tier SOI share via cost and localization, yet Smart Cut's patent moat remains intact in high-end RF and silicon-photonics integration for the foreseeable future. The 18-month wildcard: AI data-center 800V/1.5kV power architectures are pulling SOI power-MOSFET demand, while silicon-photonics interconnects create incremental demand for thin SOI substrates. If Soitec misses its Crolles Phase-2 ramp by 2026, the window hands itself to Japanese rivals.
