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 9):
The semiconductor device according to  claim 8 , wherein an inclination of a side wall of the depression in the insulating film relative to the upper surface of the semiconductor substrate is smaller than an inclination of the lower portion of the field plate relative to the upper surface of the semiconductor substrate.
