Abstract:
A method for manufacturing a solid-state imaging device, in which a photoelectric conversion portion to receive light with a light-receiving surface and generate a signal charge is disposed in a substrate, includes the steps of forming a metal light-shield layer above the substrate and in a region other than a region corresponding to the light-receiving surface, forming a light-reflection layer above the metal light-shield layer, and forming a photoresist pattern layer from a negative type photoresist film formed above the light-reflection layer, by conducting an exposing treatment and a developing treatment, wherein in the forming of the light-reflection layer, the light-reflection layer includes a shape corresponding to a pattern shape of the photoresist pattern layer, and the light-reflection layer is formed in such a way as to reflect exposure light to the photoresist film in conduction of the exposing treatment in the forming of the photoresist pattern layer.
