Abstract
A photoelectric conversion device includes a substrate provided with pixels each including a photoelectric converter that accumulates charge generated by an incidence of light, a charge holding portion that holds charge transferred from the photoelectric converter, and an amplifier unit that includes an input node that receives charge transferred from the charge holding portion, a metal film disposed over a side of a first surface of the substrate so as to cover at least the charge holding portion, and a trench structure provided in the substrate on the side of the first surface of the substrate. The photoelectric conversion device is configured such that the light is incident from the side of the first surface of the substrate. The trench structure is disposed between the photoelectric converter and the charge holding portion of a first pixel.
