Abstract:
1. A solid-state imaging device comprising: a photoelectric conversion film provided at a second surface side of a semiconductor substrate, the second surface side of the semiconductor substrate located opposite to a first surface side of the semiconductor substrate at which a wiring layer of the semiconductor substrate is formed, wherein the photoelectric conversion film performs photoelectric conversion with respect to light of a predetermined wavelength region and transmits light of other wavelength regions; a photoelectric conversion layer provided within the semiconductor substrate, wherein the photoelectric conversion layer includes a photoelectric conversion unit that performs photoelectric conversion with respect to the light of the other wavelength regions and the photoelectric conversion layer includes a photoelectric charge accumulation unit; and a charge accumulation unit provided within the semiconductor substrate, wherein the charge accumulation unit provided within the semiconductor substrate is separate from the charge accumulation unit of the photoelectric conversion layer and accumulates charge from the photoelectric conversion film.
