Abstract
A semiconductor device, including a substrate, a deposition layer deposited on the substrate, a semiconductor region selectively provided in the deposition layer, a semiconductor layer provided on the deposition layer and the semiconductor region, a first region and a second region selectively provided in the semiconductor layer, a gate electrode provided on the second region and the semiconductor layer via a gate insulating film, a source electrode in contact with the semiconductor layer and the second region, an interlayer insulating film covering the gate electrode, a drain electrode provided on the substrate, a plating film selectively provided on the source electrode at portions thereof on which the protective film is not provided, and a pin-shaped electrode connected to the plating film via solder. The second region is not formed directly beneath a portion where the plating film, the protective film and the source electrode are in contact with one another.
