Abstract: In a solid-state imaging device, a light-shielding film 10a is formed of at least one of a high melting point metal film or a high melting point metal compound film. The surface of the light-shielding film 10a is constituted by an amorphous silicon film 13. Instead of the amorphous silicon film 13, the surface of the light-shielding film may be covered with any one of a high melting point metal film containing silicon, a high melting point metal silicide film and an oxide film. Thus, the adherence between the light-shielding film 10a and the resist can be increased and the resist can be prevented from being peeled from the light-shielding film, and thus a solid-state imaging device with a high yield even with small pixels and a method for producing the same can be provided.

Abstract: On a light shielding film 7, an anti-oxidation layer 9 covering at least the light shielding film 7 is formed. The anti-oxidation layer 9 is formed under a condition which does not oxidize a surface of the light shielding film 7. The anti-oxidation layer 9 is formed of a high melting point metal compound film having a light shielding property or an insulating film having a light transmissive property. Thus, the scattering ratio of the incident light at the surface of the light shielding film 7 can be uniform among all the pixels, and as a result, a solid state imaging device having suppressed sensitivity non-uniformity can be realized. Since the surface of the light shielding film 7 is not oxidized, the thickness of the light shielding film 7 can be reduced. Thus, the present invention can comply with the demand for size reduction of the pixels.
