IMAGE PICKUP DEVICE

摘要

An image pickup device according to the present invention is an image pickup device in which a plurality of pixel are arranged in a semiconductor substrate. Each of the plurality of pixels includes a photoelectric conversion element, a floating diffusion (FD) region, a transfer gate that transfers charges in the first semiconductor region to the FD region, and an amplification transistor whose gate is electrically connected to the FD region. The photoelectric conversion element has an outer edge which has a recessed portion in plan view, a source region and a drain region of the amplification transistor are located in the recessed portion, and the FD region is surrounded by the photoelectric conversion region or is located in the recessed portion in plan view.
