Abstract
A backside-illuminated color image sensor with crosstalk-suppressing color filter array includes (a) a silicon layer including an array of photodiodes and (b) a color filter layer on the light-receiving surface of the silicon layer, wherein the color filter layer includes (i) an array of color filters cooperating with the array of photodiodes to form a respective array of color pixels and (ii) a light barrier grid disposed between the color filters to suppress transmission of light between adjacent ones of the color filters. The light barrier is spatially non-uniform across the color filter layer to account for variation of chief ray angle across the array of color filters.
