Abstract:
1. A solid-state imaging device, comprising: a first conductivity type semiconductor substrate having the imaging region and the peripheral circuit region on a main surface thereof; an imaging region formed on a main surface of the semiconductor substrate and having a plurality of light receiving portions arranged two-dimensionally and for generating signal electric charges by photoelectric conversion; a peripheral circuit region formed on a main surface of the semiconductor substrate and formed in an outer peripheral portion of the imaging region; a second conductivity type first semiconductor layer formed in the first conductivity type semiconductor substrate at a side of the main surface of the semiconductor substrate; a first conductivity type second semiconductor layer formed in the first semiconductor layer; a through electrode formed in a through hole penetrating through the semiconductor substrate in a thickness direction of the semiconductor substrate; a pad portion formed on the main surface of the semiconductor substrate and connected to the through electrode; and a side insulating film formed at a side surface of the through electrode.
