Abstract:
1. A method of manufacturing a solid-state camera device which comprises a plurality of light-receiving parts arranged at a constant interval on a substrate surface and a plurality of light-focusing parts disposed corresponding to each of the plurality of the light-receiving parts on the substrate surface so that incident light is focused on the light-receiving parts, wherein a position of each of the light-focusing parts is shifted monotonically larger toward a center of the camera region based on the position of each of the light-receiving parts corresponding to the light-focusing parts and a size along the substrate surface in the lateral direction of each of the light-focusing parts becomes gradually larger, as the location of the light-focusing part is getting closer to a peripheral camera region from a middle camera region on the substrate in front of an exit pupil, the method comprising: forming a film of a composition for the light-focusing parts on a semi-conductor substrate on which the light-receiving parts have been formed, and patterning the film of the composition for the light-focusing parts by exposing it by using a specified mask and by developing, wherein the mask comprises a transparent substrate on which closed region patterns are disposed, said closed region pattern having positions and sizes corresponding to those of the light-focusing parts.
