Abstract
According to an embodiment, there is provided a semiconductor device including a semiconductor substrate having a first surface on which an active layer having a light receiving portion is provided and a second surface to be a light receiving surface for the light receiving portion, a wiring layer provided on the active layer, an insulating layer provided to cover the wiring layer, and a supporting substrate joined to the semiconductor substrate via the insulating layer to face the first surface of the semiconductor substrate. A joined body of the semiconductor substrate and the supporting substrate includes an intercalated portion provided between its outer peripheral surface and the active surface. The intercalated portion is provided to penetrate the semiconductor substrate and the insulating layer from the second surface of the semiconductor substrate and to reach inside the supporting substrate.
