ABSTRACT:
A photoelectric conversion device having electric conversion cells capable of performing a store operation, a read operation and a refresh operation. In the store operation, a potential of a control electrode region of a semiconductor transistor is controlled using a capacitor and carriers are stored, which carriers have been generated by light excitation at the control electrode region. In the read operation, a signal under control of a voltage generated by the stored carriers is read out of a main electrode area of the semiconductor transistor. In the refresh operation, carriers stored in the control electrode region are removed. A semiconductor region of the same conductivity type as the main electrode region, is formed in the control electrode region separately from the main electrode region.
