Abstract

A lens forming method according to the present invention for forming lenses capable of focusing light on a plurality of respective photoelectric conversion sections constituting of a semiconductor apparatus is described. The method includes a lens forming step of processing a lens forming material, in which an average gradient of a γ curve indicating a residual film thickness with respect to the amount of irradiation light is between −15 and −0.8 nm·cm/mJ within the range of a residual film ratio of 10 to 50% or within the range of the amount of irradiation light of 55 to 137 mJ/cminto a lens surface shape, using a photomask with an optical transmittance that is varied according to a lens surface shape, as an exposure mask.
