Abstract:
A photoelectric conversion device comprises a photoelectric conversion unit, a floating diffusion region, a transfer transistor, and an output unit. A control electrode of the transfer transistor includes a first portion which extends along a channel width direction and overlaps a first boundary side when seen through from a direction perpendicular to a light receiving surface of the photoelectric conversion unit, and a second portion which extends along a channel length direction from one end of the first portion and overlaps a second boundary side when seen through from the direction perpendicular to the light receiving surface, and the control electrode of the transfer transistor has an L shape when viewed from the direction perpendicular to the light receiving surface.
