Abstract
A photoelectric conversion device includes a pixel isolation portion and a concavo-convex structure. The pixel isolation portion is arranged between adjacent pixels in a plurality of pixels formed in a semiconductor layer. The concavo-convex structure is formed on a light receiving surface of the semiconductor layer. The concavo-convex structure includes a trench extending toward an oblique direction from the light receiving surface to an inside of the semiconductor layer. The trench is filled with material that is different from material of the semiconductor layer positioned around the trench.
