First Demonstration of a Monolithic SiC Power IC Integrating a Vertical MOSFET with a CMOS Gate Buffer

In this study, we have realized a monolithic silicon carbide (SiC) power integrated circuit (IC) integrating a 1.2 kV-class trench gate vertical metal-oxide-semiconductor field-effect transistor (MOSFET) and a complementary metal-oxide-semiconductor (CMOS) gate buffer aiming to enhance the fast switching by eliminating the parasitic effects caused by external interconnections. The p-MOSFETs in SiC...
