Patent ID: 7768088

Claim:
A solid-state imaging device, comprising: an on-chip microlens; a light-receiving part that receives incident light condensed by the on-chip microlens; and an optical waveguide that extends from an undersurface part of the on-chip microlens toward the light-receiving part, and guides the incident light condensed by the on-chip microlens to the light-receiving part, wherein the optical waveguide is in contact with and integrated with the on-chip microlens, and wherein the on-chip microlens and the optical waveguide are formed of a same material; wherein the device further comprises a light shielding film in a cylindrical shape above the light-receiving part, and the incident light passing through the optical waveguide passes through an inside of the a cylinder formed by the light shielding film and is incident on the light-receiving part; wherein the device further comprises a color filter layer filled in the inside of the light shielding film between the optical waveguide and the light-receiving part, and a diameter of the optical waveguide is reduced toward the light-receiving part such that the optical waveguide has one of a conical shape and a polygonal pyramid shape.
