Zusammenfassung:	Because of inclusion of: a source electrode that is formed on a front surface of a semiconductor substrate and that is joined to the semiconductor substrate both at a source electrode as a first contact region that is an ohmic contact region and at a source electrode as a second contact region that is a contact region with a non-ohmic contact or the like; a back-surface electrode formed on a back surface of the semiconductor substrate; and a through hole in which an interconnection is provided that connects the source electrode as the second contact region in the source electrode with the back-surface electrode; it is possible not only to improve the corrosion resistance but also to reduce the leakage current, so that a highly-reliable semiconductor device suited for high frequency operation is provided.
