Patent ID: 7816777

Claim:
A semiconductor device comprising: a substrate; and a semiconductor element mounted on the substrate; wherein the substrate includes: a substrate body having a first surface on which the semiconductor element is mounted; a die pattern formed on the first surface and electrically connected to the semiconductor element; a plurality of recess portions formed in the substrate body; a plurality of through conductors, each formed in one of the plurality of recess portions and each extending from the first surface of the substrate body to a second surface opposite to the first surface relative to the die pattern; a plurality of first terminals, each having an opening which coincides with one of the recess portions and is electrically connected to one of the plurality of through conductors, and each having an extending portion which extends away from an edge of the corresponding one of the recess portions and away from the semiconductor element toward the outer edge of the mounting surface; and a plurality of bonding wires electrically connecting the extending portion of the first terminals with the semiconductor element.
