Abstract:
The position of the side wall of a metal electrode is precisely controlled and the coverage of a layer above the metal electrode is improved. A semiconductor device is provided, including: a semiconductor substrate; and a metal electrode formed above an upper surface of the semiconductor substrate, wherein a side wall of the metal electrode includes a lower portion contacting the semiconductor substrate, and an upper portion that is formed upper than the lower portion and has a smaller inclination relative to the upper surface of the semiconductor substrate than the lower portion. An active region formed in the semiconductor substrate is further included, and the metal electrode may be a field plate formed on an outer side relative to the active region on the upper surface of the semiconductor substrate. The upper portion of the side wall of the field plate may have an upward-convex shape.

Claim (Index 12):
A fabrication method of a semiconductor device, comprising forming a metal electrode above an upper surface of a semiconductor substrate, wherein\n forming the metal electrode includes forming a lower portion contacting the semiconductor substrate and an upper portion that is arranged upper than the lower portion and has a smaller inclination relative to the upper surface of the semiconductor substrate than the lower portion in a side wall of the metal electrode.
