Patent ID: 7429791

Claim:
A semiconductor device comprising: a radiating plate; a semiconductor chip bonded onto the radiating plate; a rectangular-shaped resin wall which surrounds the semiconductor chip bonded to the radiating plate, said rectangular-shaped resin wall having a first pair of opposing sides and a second pair of opposing sides; a conductive member extending through one of the first pair of opposing sides of the resin wall and retained by the resin wall, said conductive member is electrically connected to the semiconductor chip; and a resin lid bonded to an upper end of the resin wall, said semiconductor chip is sealed in a space enclosed by said radiating plate, said resin wall and said resin lid, said radiating plate extends outward of said second pair of opposing sides of said resin wall; wherein the radiating plate has end portions formed integrally at both ends of a center portion of the radiating plate, the lower end of the resin wall is bonded to said center portion, and said end portions are exposed through the resin wall.
