ABSTRACT:
A photoelectric conversion device comprises a first semiconductor region of a first conductivity type; a second semiconductor region of a second conductivity type serving as a photoelectric conversion element together with a part of the first semiconductor region; a gate electrode transferring electric carriers generated in the photoelectric conversion element to a third semiconductor region of the second conductivity type. Moreover, the photoelectric conversion device comprises an isolation region for electrically isolating the second semiconductor region from a fourth semiconductor region of the second conductivity type adjacent to the second semiconductor region. Wiring for applying voltage to the gate electrode is arranged on the isolation region. Here, a fifth semiconductor region of the second conductivity type having an impurity concentration lower than that of the fourth semiconductor region is provided between the fourth semiconductor region and the isolation region.
