Abstract:
A solid-state image sensing device comprising:a semiconductor substrate having an image sensing region where elements including a plurality of photoelectric conversion elements are formed and a monitor region for film thickness measurement; an insulating film formed on an entire surface of said semiconductor substrate; an electrode/interconnection selectively formed in the image sensing region on said semiconductor substrate via said insulating film; a light-shielding film formed in the image sensing region on said electrode/interconnection via said insulating film, said light-shielding film having an opening corresponding to the photoelectric conversion element; a planarizing film formed in the image sensing region on said light-shielding film and insulating film; a microlens formed on said planarizing film in correspondence with the photoelectric conversion element and the opening of said light-shielding film; and a film thickness measuring pattern formed in the monitor region and including a first multilayered structure formed from said insulating film, electrode/interconnection, light-shielding film, and planarizing film, wherein the monitor region is formed from a first region and a second region adjacent to the first region, the first region having the first multilayered structure, and the second region having only said insulating film.
