Abstract:
1. A semiconductor device comprising: a semiconductor chip integrally sealed in a face-down state by an insulating resin with a bonding electrode provided at an underside of the semiconductor chip; a pad disposed below the semiconductor chip and electrically connected to the bonding electrode of the semiconductor chip and exposed from the insulating resin at a back surface of the pad, said pad having a curved side to anchor to the insulating resin; a heat radiation electrode disposed below the semiconductor chip and exposed from the insulating resin at an underside of the radiation electrode; and a metal plate coupled to the exposed underside of the heat radiation electrode to protrude beyond the back surface of the pad, wherein the pad and the bonding electrode are superposed, and an electrical signal is picked up from the pad directly connected to the bonding electrode via a brazing material.
