Abstract
According to one embodiment, a semiconductor device includes a semiconductor substrate, a first insulating layer, an electrode pad, a through hole, a second insulating layer, and a conductive material. A through groove passes through the semiconductor substrate from a surface to an opposite surface. The first insulating layer fills the through groove. The electrode pad is connected with an interconnection layer. The second insulating layer is provided between the electrode pad and the first insulating layer. The through hole communicates with the electrode pad and passes through the first insulating layer and the second insulating layer. The conductive material is provided in the through hole so as to be connected with the electrode pad.
