Abstract:
A semiconductor device, comprising:a semiconductor substrate;a conductive portion formed on the semiconductor substrate;a metal film formed on the conductive portion, the metal film having a bottom surface including both a contacting area with the conductive portion and a non-contacting area with the conductive portion;a gold plate portion formed on an entire upper surface of the metal film;an inter-layer insulation film formed on an area of the semiconductor substrate, the area being free from the conductive portion, the metal film, and the gold plate portion in such a manner that the inter-layer insulation film contacts side walls of the conductive portion, the metal film and the gold plate portion;a refractory metal film formed in such a manner that the refractory metal film coats a whole top wall of the gold plate portion; anda protection film formed in such a manner that the protection film exposes a part of the refractory metal film on the gold plate portion as a bonding wire connecting portion and coats the inter-layer insulation film and another part of the refractory metal film.
