Patent ID: 8872239

Claim:
An image pickup device in which a plurality of pixels are arranged in a semiconductor substrate, each of the plurality of pixels comprising: a photoelectric conversion element including a first semiconductor region of a first conductivity type and a second semiconductor region of a second conductivity type, the second semiconductor region constituting a PN junction together with the first semiconductor region; a floating diffusion region of the first conductivity type; a transfer gate that transfers charges in the first semiconductor region to the floating diffusion region; and an amplification transistor whose gate is electrically connected to the floating diffusion region, wherein an outer edge of the first semiconductor region has a recessed portion in plan view, wherein the gate of the amplification transistor is disposed in the recessed portion and is surrounded by the first semiconductor region in at least two directions in plan view, and wherein the floating diffusion region is surrounded by the first semiconductor region or is located in the recessed portion in plan view.
