Patent ID: 8669632

Claim:
A solid-state imaging device comprising: a semiconductor substrate including a plurality of light-receiving portions formed therein and individually having photoelectric conversion functions; a wiring layer formed on the semiconductor substrate and having a laminated structure of an insulating film and a wire, the wiring layer having recesses in positions individually corresponding to above the plurality of light-receiving portions; a plurality of color filters formed in a manner corresponding to the plurality of light-receiving portions individually on the wiring layer; an upper layer formed on the plurality of color filters and including microlenses formed in a manner corresponding to the plurality of light-receiving portions individually, wherein each of the color filters has a refraction index higher than a refraction index of a portion of the upper layer which makes contact with an upper surface of the color filter, and an upper surface and a lower surface of each of the color filters has a concave shape respectively; and a second insulating film having a refraction index higher than a refraction index of the color filter formed on the semiconductor substrate, wherein an upper surface of the second insulating film has an upward convex shape corresponding to the concave shape of the lower surface of each of the color filters.
