Claim Text:
1. A solid-state imaging device comprising: a semiconductor substrate; a plurality of photodiodes on the semiconductor substrate having at least a first photodiode associated with a first pixel and a second photodiode associated with a second pixel; multilayer wiring on the semiconductor substrate; a first insulating film on the semiconductor substrate covering the multilayer wiring and extending over the first and second pixel, the first insulating film having a first refractive index; a second insulating film having a second refractive index higher than the first refractive index and disposed on the first insulating film and extending over the first and second pixels; and a third insulating film having a third refractive index higher than the second refractive index and disposed on the second insulating film and extending over the first and second pixels, wherein,
