Patent ID: 8710613

Claim:
A pickup device including a plurality of pixels, each pixel comprising: a photoelectric conversion portion that generates charges in accordance with incident light; a charge holding portion that includes a first semiconductor region of a first conductivity type that holds the generated charges in a portion different from the photoelectric conversion portion; and a transfer portion that includes a transfer gate electrode that controls a potential between the charge holding portion and a sense node, wherein the charge holding portion includes a control electrode that is disposed above the first semiconductor region via an insulating film, wherein a second semiconductor region of a second conductivity type, is disposed on a surface of a semiconductor region between the control electrode and the transfer gate electrode, wherein a third semiconductor region of a first conductivity type, is disposed in a charge path below the second semiconductor region and has a portion which is not overlapped with the first semiconductor region, and wherein an impurity concentration of the portion of the third semiconductor region is higher than an impurity concentration of the first semiconductor region.
