SmartSiC Technology for Faster, Better, and Greener SiC Power Devices

Silicon Carbide (SiC) power devices are now confirmed as selected platform for EV and industrial applications. Huge progresses have been accomplished in improving SiC substrates to support vertical Mosfet demonstrating world class energy efficiency now outperforming IGBT for most power applications.

Overall cost and supply of SiC remains a concern preventing wide adoption for all vehicles type, yield and maturity yet adding risk on a very capital-intensive route to bring SiC device to large volume semiconductor standard.

SmartSiC engineered substrate technology comes as an acceleration opportunity and an alternative by solving some of the main remaining issues in SiC power device HVM route:

  • integration of high quality SiC layer transfer for device yield optimization, without additional stress on the supply by 10x or more reuse of initial monocrystalline SiC substrate.
  • built on a low resistivity handle wafer to improve device electrical performance in order to gain one generation devices
  • significant reduction of capex into additional capacity to be needed to ramp to large volume needed to support wide adoption for EV.

SmartSic as an alternative generation of SiC substrate is a greener approach thanks to a much lower temperature processing to enable new wafers from same boule. As a result, while bulk SiC allows a CO2 emission advantage over IGBT thanks to energy efficiency, SmartSiC is boosting such advantage, resulting in very positive gain in environmental signature. In the environmental EV’s dynmaics, SmartSiC is definitively a faster, better and greener technology for an alternative opportunity for the next generation of SiC power devices.
