Patent ID: 7944042

Claim:
A semiconductor device, comprising: an outer resin case having a peripheral wall and multiple terminal mounting holes formed in the peripheral wall, a layer assembly provided in the outer resin case and including a semiconductor chip, an insulating circuit board on which the semiconductor chip is mounted, and a heat-dissipating metal base on which the insulating circuit board is mounted, external terminals arranged in the peripheral wall of the outer resin case and having terminal leg portions extending to inside the case, a terminal clamping frame disposed between the heat-dissipating metal base and the terminal leg portions, and bonding wires for connecting the terminal leg portions and a conductive pattern of the insulating circuit board or the semiconductor chip, wherein said multiple terminal mounting holes in the outer resin case are arranged side by side so as to conform to different terminal arrangements according to device models and specifications, and the external terminals are press-fitted into only selected ones of the multiple terminal mounting holes for the particular semiconductor device to leave unfilled terminal mounting holes.
