Abstract
According to one embodiment, in a semiconductor device, a semiconductor substrate has a first surface and a second surface which is opposed to the first surface. An insulating layer is provided on the first surface of the semiconductor substrate. A metal wiring is provided within the insulating layer. A support substrate is bonded to the insulating layer. A poly silicon electrode is connected to the metal wiring through a contact. A pad is provided on the second surface of the semiconductor substrate and is connected to the poly silicon electrode through a metal film deposited in a via-hole to penetrate the semiconductor substrate and extend to the poly silicon electrode.
