Patent ID: 7858401

Claim:
A method of manufacturing an image sensor, the method comprising: arranging a plurality of IC chips along a lens body that converges a reflection of light from an object irradiated with a light source, the IC chips being configured to receive the reflection passed through the lens body and a transparent member formed continuously over the IC chips; forming recessed refractive index changing regions in the transparent member, the refractive index changing regions being configured such that a refractive index increases continuously or stepwise inwards toward an inner portion of the transparent member from a non-recessed surface of the transparent member in a direction perpendicular to a plane that passes through the plurality of chips, the refractive index changing regions being formed at a constant interval so as to be opposite to gaps between adjacent IC chips; and disposing the transparent member between the IC chips and the lens body so that the refractive index changing regions are opposite to the gaps between adjacent IC chips to direct the converged reflection of light towards the IC chips.
