Abstract

A silicon carbide (SiC) semiconductor device having a metal oxide semiconductor field effect transistor (MOSFET) and integrated with an anti-parallelly connected Schottky diode includes: a substrate, an n-drift layer, a plurality of doped regions, a gate dielectric layer, a gate electrode, an inter-layer dielectric layer, a plurality of source openings, a plurality of junction openings, a plurality of gate openings, a first metal layer and a second metal layer. The second metal layer at the junction openings forms the Schottky diode.
