Title:
LIGHT-RECEIVING ELEMENT, SOLID-STATE IMAGING DEVICE, AND ELECTRONIC EQUIPMENT
Document Type and Number:
Japanese Patent JP2021190433
Kind Code:
A
Abstract:
To provide a light-receiving element that can improve optical symmetry and efficiently extract light in a structure in which a transfer gate electrode surrounds a floating diffusion region in a single photoelectric conversion region that constitutes a pixel.SOLUTION: The light-receiving element includes a photoelectric conversion region that constitutes a pixel, a floating diffusion region of a first conductivity type that is provided on one main surface side of the photoelectric conversion region, and a plurality of transfer gate electrodes that is provided on one main surface of the photoelectric conversion region, spaced apart from each other via a gate insulating film, and symmetrically provided with the floating diffusion region at the center in a planar pattern.SELECTED DRAWING: Figure 3
