Title:
光電変換装置及び光電変換方法
Document Type and Number:
Japanese Patent JP3621744
Kind Code:
B2
Abstract:
A photoelectric converter device having improved residual image characteristics and composed of a transistor having a control electrode region made of a semiconductor of a first conductivity type for accumulating carriers generated by an electromagnetic wave emitted by an object to be detected, a first main electrode region made of a semiconductor of a second conductivity type, and a second main electrode region made of a semiconductor of the second conductivity type, for performing an operation to accumulate the carriers, an operation of reading signals based on the carriers, and an operation of extinguishing the carriers, wherein carriers other than those generated by the electromagnetic wave emitted by the object to be detected are generated in or injected into the control electrode region. Thus, since the amount of excess majority carriers in the control electrode region after the extinguishing operation is always kept substantially constant, improved residual image characteristics are obtained.
