Abstract:
1. A solid-state imaging device comprising: a semiconductor layer with oppositely facing first and second surfaces and including therein a photoelectric conversion section operable to receive incident light and generate a signal charge; a wiring layer on the second surface of the semiconductor layer; a gate insulating layer on the second surface of the semiconductor layer; at least one transistor with source/drain regions in the semiconductor layer and the gate insulting layer between a gate of the transistor and the semiconductor layer; and a light absorbing section on the second surface and interposed between the photoelectric conversion section and the wiring layer, the light absorbing section including a diode directly on a portion of the photoelectric conversion section or with the gate insulating layer between the diode and the photoelectric conversion section, the diode effective to (i) absorb transmitted light transmitted through the photoelectric conversion section and (ii) prevent the transmitted light from passing through the light absorbing section to the wiring layer, wherein,
