Claim:
1. A semiconductor device comprising: a semiconductor substrate including an upper surface, a lower surface located opposite to the upper surface and serving as an active surface, and a through hole that extends through the semiconductor substrate from the upper surface to the lower surface; an insulative layer formed from a resin and including an upper surface, a lower surface located opposite to the upper surface of the insulative layer to cover the upper surface of the semiconductor substrate, and an opening, wherein the opening of the insulative layer is aligned with the through hole; an insulative film that covers an inner wall surface of the through hole and an inner wall surface of the opening of the insulative layer; and a through electrode formed in the through hole and the opening of the insulative layer inward from the insulative film, wherein the through electrode includes an upper end surface that forms a pad exposed from the upper surface of the insulative layer, wherein the upper end surface of the through electrode is at a same level as the upper surface of the insulative layer.
