Patent ID: 8293559

Claim:
A method of manufacturing a photoelectric conversion device, the method comprising: a providing step of providing a substrate including a pixel region and a peripheral circuit region, wherein a diffusion layer is arranged in the pixel region, a member containing metal is arranged in at least one of the pixel region and the peripheral circuit region, and the diffusion layer and the member are covered with an insulating layer; a first step that includes forming a first contact hole in the insulating layer to expose the diffusion layer; a second step that includes forming a second contact hole in the insulating layer to expose the member; and a doping step of doping an impurity into the diffusion layer via the first contact hole, wherein the method satisfies one of conditions (1) and (2): (1) the second step is performed in a state where the first contact hole is filled; and (2) the first step is performed after the second step.
