摘要:
A Schottky barrier diode comprises a semiconductor layer configured to include a surface and a plurality of recesses that are recessed relative to the surface; and a Schottky electrode arranged to form a Schottky contact with the surface. When the semiconductor layer is viewed from a surface side thereof, the surface is arranged continuously, and distances on the surface between adjacent recesses are substantially identical. This configuration suppresses a photoresist from being left in any unintended portion.
