Abstract:
1. A semiconductor device comprising: a semiconductor substrate; a surface electrode that is formed on a surface of the semiconductor substrate; an interlayer insulation layer that is formed on the surface of the semiconductor substrate; a pad which is formed on a surface of the interlayer insulation layer, and to which a conductive wire is connected; a surface insulation layer that is formed on a surface of the surface electrode; and a protective coating, that is formed on a surface of the insulation layer, and that is used to protect the surface insulation layer from a cut end of the conductive wire connected to the pad, wherein the protective coating is formed at a position near the pad, a height of the protective coating decreases toward the pad and toward the cut end of the conductive wire, a surface of the protective coating facing towards the cut end is an inclined surface that is downwardly inclined toward the cut end of the conductive wire, and an inclination angle of the surface of the protective coating facing towards the cut end is smaller than an inclination angle of a surface of the protective coating on a side opposite to the cut end.
