ROHM Semiconductor Partners With AIXTRON SE To Scale In-House GaN Power Device Production Using The G10-GaN Platform - marketscreener.com

ROHM Semiconductor's strategic partnership with AIXTRON SE represents a significant move in the power semiconductor sector, leveraging the G10-GaN platform to expand in-house gallium nitride device pr... Read original →

ROHM’s alliance with AIXTRON on the G10-GaN platform marks a vertical reconfiguration of wide-bandgap semiconductor manufacturing. Technically, it forces tighter co-optimization between MOCVD process parameters and device architecture, accelerating 8-inch GaN-on-Si substrate maturity while narrowing SiC’s window in mid-voltage applications. From a compliance standpoint, as Western export controls tighten on critical tools, ROHM secures supply by locking in German equipment—but at higher capex and localization costs. Competitors like Infineon and STMicroelectronics will likely fast-track their own GaN fabs or diversify equipment sourcing, while Taiwan, China-based players such as Navitas face heightened scrutiny over supply chain geopolitics. Within 18 months, this move will push GaN power device yields past 90%, triggering mass adoption in EV onboard chargers and solar inverters, and cementing an integrated ‘equipment-material-device’ moat.
