Abstract
The invention provides a manufacturing method of a solid-state image sensing device where light-receiving sensitivity is improved. The manufacturing method of the solid-state image sensing device of the invention has forming an insulating film on a light-receiving region and a non-light-receiving region, forming a mask pattern for forming a lens on the insulating film on the light-receiving region and a dummy mask pattern for forming a lens on the insulating film on the non-light-receiving region, forming a plurality of convex portions on the insulating film by etching the insulating film by using the mask pattern and the dummy mask pattern as a mask, forming a first lens film on the insulating film, forming a planarizing film having a lower etching rate than the first lens film on the first lens film, etching back the first lens film and the planarizing film, and forming a second lens film on the first lens film.
