Abstract
A photoelectric conversion device has a semiconductor region for accumulating the carriers generated by photoexcitation which reads the signals according to the accumulated carriers in said semiconductor region. A stabilizing electrode is provided above the surface where the semiconductor region is formed.
Claims16
A photoelectric conversion device comprising:
- a first region of a first conductivity type;
- a second region of a second conductivity type disposed adjacent to said first region;
- a third region of the first conductivity type provided within said second region;
- a fourth region of the second conductivity type electrically connected to said second region;
- fifth region of the second conductivity type disposed adjacent to said first region;
- an electrode electrically connected to said first region;
