Patent ID: 7969007

Claim:
A semiconductor device comprising: a semiconductor substrate comprising a circuit element formed in a top surface thereof; a first insulation film disposed on the top surface of the semiconductor substrate; a metal pad connected to the circuit element and disposed at least partially on the first insulation film adjacent a lateral edge of the top surface; a second insulation film disposed on a side surface and a bottom surface of the semiconductor substrate; a metal wiring disposed on the second insulation film so as to be connected to a bottom portion of the metal pad, the metal wiring extending from the bottom surface to the side surface of the semiconductor substrate; a protection layer covering the metal wiring so that a thickness of an edge portion of the protection layer is larger than a sum of thicknesses of the semiconductor substrate, the first and second insulation films and the metal wiring; and a conductive terminal connected to the metal wiring through an opening formed in the protection layer.
