Abstract
A semiconductor device includes a semiconductor chip, an insulated circuit board on which the semiconductor chip is disposed, a cooling plate having a second front surface to which the insulated circuit board is disposed, a bonding member which bonding the insulated circuit board to the cooling plate, a case which surrounds the semiconductor chip and the insulated circuit board and is bonded to the second front surface of the cooling plate with an adhesive therebetween and a sealing member which seals the semiconductor chip and the insulated circuit board over the cooling plate in the case. The cooling plate has a coupling portion which is a projection or a recess at the second front surface of the cooling plate, and the coupling portion has an engaging surface that is inclined to form an acute angle with the second front surface of the cooling plate.
