Abstract

The picture quality of a solid-state image sensing device is improved and its manufacturing process is simplified. The solid-state image sensing device comprises an interlayer film having a recess above a light receiving sensor unit as well as an intra-layer color filter having a protuberance formed by filling the recess in accordance with the curved surface of the recess, the protuberance having a curvature required for collecting the incident light onto the light receiving sensor unit.
