Patent ID: 8809922

Claim:
A solid-state image sensing device, comprising: a first photoelectric conversion element having a first semiconductor region of a first conductivity type formed inside a semiconductor substrate; a second photoelectric conversion element having a second semiconductor region of the first conductivity type formed at a deeper position of the semiconductor substrate than the first photoelectric conversion element; a gate electrode laminated on the semiconductor substrate and to which a predetermined voltage is applied at a charge transfer time at which a signal corresponding to charges photoelectrically converted by the first photoelectric conversion element and the second photoelectric conversion element is read; a floating diffusion region to which the charges accumulated in the first photoelectric conversion element and the second photoelectric conversion element are transferred at the charge transfer time, the floating diffusion region having an eighth semiconductor region of a second conductivity type formed at the shallowest position in the semiconductor substrate and having the highest impurity concentration in the solid-state image sensing device and having a ninth semiconductor region of the second conductivity type formed at a deeper position of the semiconductor substrate than the eighth semiconductor region and formed at a shallower position of the semiconductor substrate than a third semiconductor region, wherein the second conductivity type has a charge opposite to the first conductivity type; and the third semiconductor region of the first conductivity type arranged so as to be overlapped with the ninth semiconductor region and the third semiconductor region arranged so as to be between the first semiconductor region and the second semiconductor region in a depth direction of the semiconductor substrate and so as to be overlapped with the gate electrode when seen in a plan view.
