Infineon to Build Europe’s First High-Volume 300mm GaN Power Semiconductor Manufacturing Facility - ELE Times

This is not a capacity expansion—it is Europe's structural correction of its 'strong design, weak manufacturing' gap in power semiconductors. Technical ripple: The real bottleneck in 300mm GaN is substrate yield and MOCVD uniformity, not epitaxy itself. Global 300mm MOCVD installations number fewer than 50, so Infineon's ramp will directly pull equipment orders from Veeco and Aixtron while forcing substrate suppliers to accelerate 300mm yield. Downstream, 800V EV inverters and AI data-center power supplies are the killer applications; a 30-40% per-die cost reduction pushes GaN past the tipping point of mainstream Si MOSFET substitution. Compliance and supply chain: The line is almost certainly tied to EU Chips Act subsidies, yet epi equipment and certain substrates remain dependent on Taiwan, China and Japanese suppliers—a non-trivial disruption exposure. Patent boundaries between GaN-on-Si and GaN-on-SiC routes are still contested; larger volume means larger litigation surface. Competitive dynamics: STMicroelectronics, the closest European rival, still runs GaN on 150mm wafers, handing Infineon a 12-18 month first-mover window. Navitas and EPC will not follow into heavy-asset manufacturing; they will lean harder on foundry partnerships to offset cost. Rohm and Toshiba, locked into Japanese automotive chains, will react slowly. Outlook: Within 18 months, GaN penetration in automotive main-drive inverters should break past 15% from under 5%, with AI server power as the second growth vector. The strategic essence: lock in European OEM design-wins through manufacturing-scale economics, turning 'Made in Europe' from rhetoric into a BOM-level cost advantage.
