Patent ID: 8810026

Claim:
A semiconductor module comprising: a semiconductor device; a wiring member that is connected to the semiconductor device; a cooling plate that includes a first surface on a side of the semiconductor device and a second surface on a side opposite to the first surface and has a fastening portion at an end thereof in a first direction; a molded portion that is formed by molding a resin on the semiconductor device, the wiring member and the cooling plate, a heat sink part that is provided between the semiconductor device and the first surface of the cooling plate on the side of the semiconductor device; and an insulating material that is provided between the heat sink part and the first surface of the cooling plate on the side of the semiconductor device; wherein the fastening portion is exposed out of the molded portion, and a terminal portion of the wiring member is exposed out of the molded portion such that the terminal portion of the wiring member extends in a second direction which is substantially perpendicular to the first direction, the heat sink part and the insulating material are disposed in the molded portion, the cooling plate includes fins on the second surface, the insulating material includes an end that extends outwardly with respect to an end of the heat sink part, and the fins of the cooling plate are formed at a center side with respect to the end of the heat sink part.
