Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate; a plurality of photoelectric conversion films stacked in a direction perpendicular to a surface of the semiconductor substrate, the photoelectric conversion films detecting different colors contained in an incident light; and a plurality of pixel electrode films on each of the photoelectric conversion films, the pixel electrode films being partitioned in accordance with pixels, wherein the semiconductor substrate includes: a plurality of color selection transistors corresponding to one of the pixels, wherein the color selection transistors each corresponds to one of the photoelectric conversion films and connects to one of the pixel electrode films on the one of the photoelectric conversion films so as to be capable of selecting the one of the photoelectric conversion films; and a charge detection cell corresponding to one of the pixels, wherein the charge detection cell is common to the photoelectric conversion films, and the charge detection cell reads out an image signal to an image signal readout line in accordance with a signal charge generated in each of the photoelectric conversion films.
