Patent ID: 8022515

Claim:
A semiconductor device, comprising: a lead frame including an element support and a lead portion having inner leads and outer leads, the lead frame having an area from the element support to the inner leads formed flat; a first semiconductor element having a first electrode forming surface on which first electrode pads are formed, the first semiconductor element being adhered to the lead frame via a first adhesive layer; first metal wires electrically connecting the inner leads and the first electrode pads; and a resin sealer sealing the first semiconductor element together with the first metal wires, the resin sealer having a rectangular shape with two long edges and two short edges, wherein the first electrode pads are arranged along one edge of the first semiconductor element corresponding to one of the two long edges of the resin sealer, the outer leads are disposed to respectively protrude from the two short edges of the resin sealer, and are bent in a direction which a lower surface of the lead frame faces, a first group of the inner leads in a first region are inflected from a first group of the outer leads that protrude from a first of the short edges of the resin sealer toward the edge of the first semiconductor element where the first electrode pads are arranged, and a second group of the inner leads in a second region are inflected from a second group of the outer leads that protrude from a second of the short edges of the resin sealer toward the edge of the first semiconductor element where the first electrode pads are arranged.
