Claim Text:
1. A semiconductor device comprising: semiconductor elements; a lead including a plurality of island portions on which the semiconductor elements are mounted; a common heat dissipation member for dissipating heat from each of the island portions, the common heat dissipation member having a common continuous flat surface; a bonding layer bonding the common continuous flat surface of the common heat dissipation member to each of the island portions; and a sealing resin covering the semiconductor elements, the island portions and a part of the common heat dissipation member; wherein the bonding layer includes individual regions provided for the island portions, respectively, the individual regions being spaced apart from each other on the common continuous flat surface, the sealing resin fills a space formed between adjacent ones of the individual regions, thereby being held in direct contact with the common continuous flat surface, and the bonding layer is formed of an adhesive made of a resin, the bonding layer being held in direct contact with the common heat dissipation member.
