Abstract: A solid-state imaging device includes: a first electrode formed above a semiconductor substrate; a photoelectric conversion film formed on the first electrode and for converting light into signal charges; a second electrode formed on the photoelectric conversion film; a charge accumulation region electrically connected to the first electrode and for accumulating the signal charges converted from the light by the photoelectric conversion film; a reset gate electrode for resetting the charge accumulation region; an amplification transistor for amplifying the signal charges accumulated in the charge accumulation region; and a contact plug in direct contact with the charge accumulation region, comprising a semiconductor material, and for electrically connecting to each other the first electrode and the charge accumulation region.
