Abstract
A semiconductor module includes a semiconductor device, and a cooling device. The semiconductor device includes a semiconductor chip and a circuit board for mounting the chip. The cooling device includes a top plate mounted in the semiconductor device and having a side wall connected thereto, a bottom plate connected to the side wall, and a refrigerant circulating portion, defined by the top plate, the side wall, and the bottom plate and has a substantially rectangular shape with a cross section parallel to a main surface of the top plate having long and short sides. The circuit board is a substantially rectangular laminated circuit board including an insulating plate having an upper surface with a circuit layer and a lower surface with a metal layer. In a plan view, at least one corner of the metal layer at least partially overlaps with the slope portion of the side wall.
