Abstract:
1. A semiconductor device, comprising: a semiconductor chip within which a field effect transistor is incorporated, the semiconductor chip having a main surface, a back surface opposite said main surface, a first side, a second side opposite said first side, a drain electrode on said back surface thereof, and a source electrode and a gate electrode on said main surface thereof; a metal-made support board having a top surface and a bottom surface opposite said top surface, said semiconductor chip being mounted on said top surface of said metal-made support board; a source lead connected to said source electrode of said semiconductor chip electrically; a gate lead connected to said gate electrode of said semiconductor chip electrically; and a sealing body comprised of an insulating resin, said sealing body sealing said semiconductor chip and respective portions of said source and gate leads, and wherein said semiconductor chip has a substantially quadrangular shape, said first and second sides of said semiconductor chip extend in a first direction, and said source and gate leads extend in a second direction that intersects said first direction in a plain view, wherein said second side is closer to said source and gate leads than said first side, and said gate electrode is disposed at a corner portion of the semiconductor chip that is more proximate to said first side than said second side in said plain view and thereby said gate electrode is located more proximate to said first side than said second side, and wherein said source electrode is connected to said respective portion of said source lead by a plurality of first bonding wires.
