Abstract

A semiconductor device comprises a semiconductor layer including a mesa structure and a peripheral surface extending around the mesa structure, the mesa structure having a plateau shape with an upper surface and a side surface; a Schottky electrode forming a Schottky junction with the upper surface; an insulating film extending from the peripheral surface, across the side surface, and onto the Schottky electrode, the insulating film having an opening formed on the Schottky electrode; and a wiring electrode electrically connected to the Schottky electrode inside the opening, the wiring electrode extending from inside of the opening, across a portion of the insulating film formed on the side surface, and onto another portion of the insulating film formed on the peripheral surface.
