Abstract

PURPOSE:To improve the dynamic range, sensitivity and resolution etc. by a method wherein an excess majority carrier storage region is constructed by a cell provided with a refresh transistor and a read-out transistor. CONSTITUTION:An optical input transmitted through a transparent electrode applied with a constant bias Vs generates an electron positive holes pair at a high resistance layer 6 near an n<+> layer 5. The generated electrons are absorbed in the n<+> layer 5 and the positive holes are stored in a p<+> region 7. Thereby, the electrons in the n<+> region 8 are flowed to the substrate side getting beyond the thin p<+> region 7 in thickness. At the same time, the n<+> region 8 is increasingly biased to the positive. A voltage proportionatal to a quantity obtained by time-integrating the photon density of the input light can be obtained in the n<+> region 8. The voltage appears on a bit line 2.
