Abstract:
1. A photoelectric conversion apparatus comprising: a photoelectric conversion portion including a first semiconductor region of a first conductivity type arranged in a semiconductor substrate; a charge holding portion including a second semiconductor region of the first conductivity type arranged in the semiconductor substrate and configured to hold a charge generated by the photoelectric conversion portion; a third semiconductor region of the first conductivity type arranged in the semiconductor substrate; a first gate electrode arranged on a region between the second semiconductor region and the third semiconductor region and configured to transfer a charge of the second semiconductor region into the third semiconductor region; and an isolation portion including a first part, a second part and a third part of an insulator, wherein the first semiconductor region is arranged between the first part of the insulator and the second semiconductor region in a first cross section including a first direction along which the first semiconductor region and the second semiconductor region are arranged, the second semiconductor region is arranged between the second part and the third part of the insulator in a second cross section including a second direction intersecting the first direction, and in the second cross section, the second semiconductor region is arranged at a depth shallower than a bottom of the second part and a bottom of the third part of the insulator.
