While Tesla aims to reduce the amount of silicon carbide (SiC) components by 75%, sources in the related industrial sectors nevertheless believe that SiC, with its good heat resistance capability, will remain mainstream in the application of automotive inverters. However, it is inevitable for major IDMs and automotive supply chain players to work on the further reduction of chip size and maintain high power density. A return to silicon-based IGBT or a mixed solution would also shed more light on the advanced packaging.
