Patent ID: 7432589

Claim:
A semiconductor device comprising: a semiconductor element having a pair of electrodes; a housing having a recess for accommodating the semiconductor element; a first lead electrode and a second lead electrode exposed on the bottom surface of said recess; an adhesive layer for die bonding between the semiconductor element and the first lead electrode; and electrically conductive wires for wire bonding between one electrode of the pair of electrodes of the semiconductor element and the first lead electrode and between the other electrode and the second lead electrode, wherein the housing has at least one wall formed to extend across the bottom surface of the recess so as to divide the surface of the first lead electrode into a die bonding area and a wire bonding area; the first lead electrode has a notch which is formed by cutting off a portion of an edge of the first lead electrode and located at least just below the wall; and the wall and the bottom portion of said housing are connected to each other through the notch.
