<p>The device comprises a transistor having a region (5) of a first conductivity type and a control region (6) of a second conductivity type A capacitor (9,6) in a floating condition controls the potential of the control region (6). The device operates to store photogenerated carriers in the control region (6), read the stored voltage and refresh the stored carriers, and is formed to have a multilayer structure such that at least the capacitor (9,6) is formed under a region (16) in which the carriers are photogenerated. …<IMAGE>… </p> |
