ABSTRACT:
A very high sensitive solid state imager is realized by employing a multiplication process which includes avalanche multiplication of charges as generated by an incident light at each of several optical to electrical converting components (hereafter referred to as a photosite). Thus, the functions of a high speed electron shutter are obtained. Notwithstanding a high sensitivity, a reduced supply voltage for avalanche multiplication can be realized by laminating a transparent electrode of poly-silicon or ITO on a photosite, applying an avalanche multiplication voltage thereupon through its capacity coupling, and simultaneously applying a negative voltage on a read-out gate during a readout time. Furthermore, a reduced readout voltage can also be realized by laminating a transparent electrode of poly-silicon or ITO, on a photosite, and applying a voltage of polarity opposite to that applied during an avalanche multiplication time.
