BorgWarner to Integrate STMicroelectronics? Silicon

STMicroelectronics will supply BorgWarner Inc. with the latest third generation 750V silicon carbide (SiC) power MOSFETs dice for their proprietary Viper-based power module. This power module is used in BorgWarner?s traction inverter platforms for several current and future Volvo Cars electric vehicles. To fully leverage the performance of ST?s SiC MOSFET dice, BorgWarner collaborated closely with ST?s technical team to match their die with BorgWarner?s Viper power switch, thereby maximizing inverter performance and delivering a compact and cost-effective architecture.

The collaboration between the companies provides the high-volume capability that is required by the quickly growing EV market. ST?s high-volume STPOWER SiC products are manufactured in its fabs in Italy, and Singapore, with advanced packaging and testing at its back-end facilities in Morocco and China. In October 2022, ST announced it would expand its wide bandgap manufacturing capacity with a new integrated SiC substrate manufacturing facility in Catania, home to the company?s power semiconductor expertise and the site of integrated research, development, and manufacturing of SiC.
