ABSTRACT:
A semiconductor device has a structure capable of connecting a lead terminal directly to an electrode on a front surface thereof. The semiconductor device includes a first main electrode provided on the front surface, a second main electrode provided on a back surface, and a metal film provided so as to cover at least a portion of a surface of the first main electrode and for soldering the lead terminal thereto. Here, the metal film includes a plurality of opening portions through which the surface of the first main electrode is exposed.
