Abstract
A method of manufacturing a color charge-coupled device is disclosed including the steps of alternately forming a plurality of light detectors corresponding to first to third colors and a plurality of charge transmission regions on a semiconductor substrate; forming a pad on one side of the substrate excluding a portion where the light detectors and charge transmission regions are formed; forming a planarizing film on the substrate excluding the pad; coating a microlens material on the planarizing film and patterning the microlens material so as to be left only on the planarizing film above the light detectors; thermally flowing the microlens material, to thereby form microlenses on the planarizing film above the light detectors; and hard-baking first to third dyeing layer, to thereby form first to third color filter layers on each microlens excluding the edge portion.
