A semiconductor device having a substrate including a photodiode; a resin layer formed on an upper surface of the substrate, the resin layer not covering a light receiving region of the photodiode, the resin layer including at least one groove surrounding the light receiving region; and a molding resin portion formed by mold-sealing the photodiode with the resin layer thereon so as not to cover the light receiving region.

A method for manufacturing a semiconductor device, includes the steps of: forming a resin layer on an upper surface of a substrate including a photodiode such that the resin layer does not cover a light receiving region of the photodiode; forming at least one groove in the resin layer so as to surround the light receiving region; and subsequently mold-sealing the photodiode by loading the substrate into a mold and filling the mold with a molding resin.
