SiC MOSFET Tech: BorgWarner Collaboration

STMicroelectronics, via its official social media platform, recently unveiled its collaboration with BorgWarner to provide cutting-edge third-generation 750V Silicon Carbide (SiC) Power MOSFET chips. These advanced chips are destined for BorgWarner's Viper power module, which is set to play a pivotal role in the electric drive inverter platform for Volvo and other forthcoming electric vehicle models.

In a concerted effort to harness the full potential of STMicroelectronics' SiC MOSFET technology, technical teams from both STMicroelectronics and BorgWarner have forged a close partnership. Their aim is to ensure seamless integration between STMicroelectronics' SiC chips and BorgWarner's Viper power switches, thereby optimizing inverter performance, reducing the physical footprint of electric drive systems, and enhancing cost-efficiency.

Marco Monti, President of STMicroelectronics' Automotive and Discrete Group (ADG), emphasized that this collaboration is poised to not only elevate the performance and range of Volvo's electric vehicles but also bolster the production capacity and availability of SiC, providing invaluable support to global players in the automotive and industrial sectors as they embark on electrification and efficiency enhancement initiatives.

It's noteworthy that STMicroelectronics currently manufactures STPOWER SiC power chips at two prominent frontend facilities situated in Italy and Singapore. Additionally, state-of-the-art packaging and testing operations are conducted at backend manufacturing facilities in Morocco and China. In a strategic move announced in October 2022, STMicroelectronics plans to expand the production capacity of its wide bandgap product portfolio and establish a comprehensive SiC substrate manufacturing facility in Catania, Italy. Catania serves as both a vital hub for STMicroelectronics' power semiconductor technology development and a center for silicon carbide research and manufacturing.
