Amplifying type photoelectric converting device and amplifying type solid-state imaging apparatus using the same

摘要

An amplifying type photoelectric converting device is disclosed. The device includes: a semiconductor substrate of a first conductive type; a well portion of a second conductive type for accumulating signal charges generated by photoelectric conversion; a semiconductor region of the first conductive type provided in a region in the well portion; a first gate region including a first electrode; and a second gate region being adjacent to the first gate region and including a second electrode. An active element is formed between the semiconductor region and the semiconductor substrate, and a change in an operational characteristic of the active element which is generated by the signal charges is used as an output signal.
