Abstract:
1. A method of manufacturing a solid-state image sensor, comprising: forming light-receiving elements in a light-receiving area; forming micro-lenses corresponding to the light-receiving elements; forming a transparent film on the micro-lenses for moderating an incidence angle of oblique light, entering the solid-state image sensor from above the solid-state image sensor, at a periphery of the light-receiving area; and arranging the light-receiving elements, the micro-lenses, and the transparent film such that, in a central portion of the light-receiving area, a corresponding one of the micro-lenses is directly above a corresponding one of the light-receiving elements, and in a portion of the light-receiving area that is closer to the periphery of the light-receiving area than a center of the light-receiving area, corresponding ones of the micro-lenses are offset from directly above corresponding ones of the light-receiving elements, the micro-lenses being arranged to collect the light of which the incidence angle has been moderated by the transparent film.
