Abstract:
1. A solid-state imaging device comprising: a semiconductor substrate; a plurality of photodiodes on the semiconductor substrate; the plurality of photodiodes including a first photodiode associated with a first pixel, a second photodiode associated with a second pixel, and a third photodiode associated with a third pixel; a first insulating film on the semiconductor substrate to cover multilayer wiring on the semiconductor substrate, the first insulating film having a first refractive index lower than a refractive index of the semiconductor substrate for at least bottom surface and top surface portions of the first insulating film; a second insulating film having a second refractive index higher than the first refractive index and being disposed on the first insulating film; a third insulating film having a third refractive index higher than the second refractive index and being disposed on the second insulating film; and a color filter on the third insulating film, the color filter having at least a first color region for the first pixel to transmit a first color, a second color region for the second pixel to transmit a second color, and a third color region for the third pixel to transmit a third color, wherein,
