ABSTRACT:
A photoelectric conversion device having a transistor made of a main electrode region of a first conductivity type and a control electrode region of a second conductivity type opposite to the first conductive type; and a capacitor in a floating condition for controlling the potential of the control electrode region; the photoelectric conversion device operating to store light-induced carriers in the control electrode region, read the stored voltage and refresh the stored carriers; and wherein the photoelectric conversion device is formed to have a multilayer structure such that at least the capacitor for controlling the potential of the control electrode region is formed under a photoelectric conversion region where the carriers are light-induced.
