ABSTRACT:
A resin-sealed semiconductor device comprises a die pad which has through holes. Thin metal films are provided on the surfaces of the die pad except for the wall surfaces of the holes. A resin, which is used for integral molding of the die pad and a semiconductor element, flows into the holes during molding. The semiconductor device so mounted does not induce cracks in the resin and, thus, has good moisture resistance.
