Abstract:
1. A solid-state image pickup device, comprising: a semiconductor substrate with a first specific resistance; a semiconductor layer continuously provided along an entire continuous first surface of said semiconductor substrate, and having a second specific resistance smaller than said first specific resistance; and a light receiving section provided in said semiconductor layer adjacent to said first surface of said semiconductor substrate, wherein a p-n junction is provided in said semiconductor layer, and said p-n junction is formed by said semiconductor layer and said light receiving section, wherein photoelectric conversion of incident light from an image-pickup object onto a second surface of said semiconductor substrate, which is on the opposite side of said first surface, is performed in the inside of said semiconductor substrate or the inside of said semiconductor layer, and electric charges generated by said photoelectric conversion are received by said light receiving section for image pickup of said image-pickup object, and wherein the specific resistance of a part of said semiconductor layer that overlaps said light receiving section in a plan view is equal to that of the other part of said semiconductor layer that does not overlap said light receiving section in the plan view.
