Method of making a planar color filter array for CCDS from dyed and mordant layers

摘要

An image sensor which includes an integral color filter array and a method of making such sensor is disclosed. The sensor includes a semiconductor substrate having an overlying support layer with an optically planar surface, a plurality of spaced image pixels formed in the substrate; and an array of contiguous color filter elements overlying the planar surface whose top surfaces are coplanar and which have no overlap of color filter material between adjacent color filter elements.
