Abstract
In SiC-MOSFETs including Schottky diodes, passage of a bipolar current to a well region in an edge portion of an active region cannot be sufficiently reduced, which may reduce the reliability of elements. In a SiC-MOSFET including Schottky diodes, the Schottky diodes formed in a terminal region are made higher in density in a plane direction than those formed in the active region or intervals between the Schottky diodes in the plane direction are shortened, without an ohmic connection between the well and the source in the terminal region.
