Abstract
A semiconductor device concerning the embodiment includes a semiconductor layer which has a first surface and a second surface which is opposite to the first surface, an interlayer which is provided on the first surface and which consists of only metal whose standard oxidation-reduction potential is not lower than 0 (zero) V in an ionization tendency, and an electrode provided on the interlayer. The semiconductor device further includes an electrical conductive layer which covers an inside of a hole which is formed in the semiconductor layer so as to reach the interlayer the interlayer from the second surface, and which is electrically connected to the electrode via the interlayer which is exposed to a bottom of the hole.
