Abstract:
A solid-state image sensor based upon a solid-state image sensor provided with a photoelectric conversion part of a conductive type reverse to one conductive type of a semiconductor region, the reverse conductive type of a drain region formed in the semiconductor region and formed opposite to the photoelectric conversion part and MOSFET for control using the reverse conductive type of a region formed between the photoelectric conversion part and the drain region for a channel region for control for outputting the variation of the electric potential of the photoelectric conversion part by electric charges generated in the photoelectric conversion part via a source-follower amplifying circuit, wherein:the photoelectric conversion part is provided with a first photoelectric conversion part and a second photoelectric conversion part; the channel region for control is located between the second photoelectric conversion part and the drain region; and MOSFET for setting constant potential using a region between the first photoelectric conversion part and the second photoelectric conversion part for a channel region for setting constant potential is formed between the first photoelectric conversion part and the second photoelectric conversion part.
