ROHM Co., Ltd. and STMicroelectronics have signed a multi-year silicon carbide (SiC) wafers supply agreement to SiCrystal, a ROHM group company.The agreement covers the supply of US$120 million of advanced 150mm SiC wafers by SiCystal to STMicroelectronics during this period of ramp-up SiC power devices.

The long-term supply agreement comes on top of the external capacity STMicroelectronics have already secured and the internal capacity it is ramping up. It will enable the company to increase the volume and balance of the wafers it needs to meet the strong demand.

The adoption of power solutions with SiCs is accelerating in both the automotive and industrial markets. With this agreement, the two companies will contribute to the widespread use of SiC in these markets.
