Abstract

A silicon carbide semiconductor device includes a junction barrier Schottky diode including a substrate, a drift layer, an insulating film, a Schottky barrier diode, and a plurality of second conductivity type layers. The Schottky barrier diode includes a Schottky electrode and an ohmic electrode. A PN diode is configured by the plurality of second conductivity type layers and the drift layer, and the plurality of second conductivity type layers is formed in stripes only in a direction parallel to a rod-shaped stacking fault.
