Abstract:
A method of manufacturing a solid-state imaging device, comprising theforming a first insulating layer on a semiconductor substrate; depositing light shielding material having light reflection characteristics entirely on the first insulating layer; selectively patterning the light shielding material to form light shielding layers having higher reflection factor than that of the substrate, and light shielding layers being disposed in a region where a CCD shift register is formed thereunder; forming a second insulating layer on the entire surface; depositing a photosensitive filter material on the second insulating layer; setting a photomask having a pattern for covering openings formed by said light shielding layers over the photosensitive filter material; and exposing the photosensitive filter material using a first light directly irradiated and a second light reflected from said light shielding layer to form a patterned filter layer, end portions of the filter layer and those of the light shielding layers being in a self-alignment state.
