Infineon opens new backend semiconductor plant ... - Pluang

Infineon's backend capacity push is a strategic repositioning: the binding constraint in power semiconductors has migrated from wafer fab to module-level packaging and thermal integration. This move compresses OEM lead times and structurally outpaces ST and ON Semi in SiC module yield. On compliance, the EU Chips Act subsidy framework demands a domestic closed loop. Backend localization is a pragmatic hedge against Asia-dependent OSAT exposure. Yet the 8-to-10-year depreciation cycle means that if EV adoption decelerates and utilization drops below 70% by 2026, margin erosion will be acute. Competitively, StarPower and CRRC are scaling mid-tier IGBT modules at aggressive pace. If Infineon anchors exclusively in premium SiC packaging, the mid-market cedes ground quarter over quarter. The 18-month wildcard: AI data center 800V power architectures are generating a structural demand surge for power modules. Whoever locks in backend capacity first captures the next pricing cycle outright.
