Patent ID: 8546933

Claim:
A semiconductor apparatus comprising; a metal base; a frame-shaped resin case bonded to the metal base for forming a space, in which a semiconductor chip is housed; an adhesive coating groove holding an adhesive at a predetermined position for bonding the resin case to the metal base, the adhesive coating groove being formed in a bonding plane of the resin case facing the metal base, the adhesive coating groove extending continuously along all peripheral sides of the bonding plane; an adhesive escape space formed between a top plane of a side wall of the adhesive coating groove and the metal base, the top plane being spaced apart from a plane containing the bonding plane for introducing and receiving therein an excess amount of the adhesive coated to the adhesive coating groove; and a flowing-out-adhesive receiver groove formed in the bonding plane, the flowing-out-adhesive receiver groove being adjacent to the adhesive coating groove and communicating to the adhesive escape space.
