Patent ID: 7195848

Claim:
A method of making a color filter array on a first substrate comprising the steps of: a) coating a resist as an adhesion promoting layer over a first substrate; b) providing at least one heat transferable colorant layer having heat transferable colorant materials on a second substrate and positioning the second substrate such that the heat transferable colorant layers are in transferable relationship with but spaced apart from the first substrate; c) heating the second substrate sufficiently to cause substantially all of the heat transferable colorant materials to transfer across the space to the adhesion promoting layer on the first substrate; d) coating the first colorant layer with a silicon containing material; e) coating the silicon containing material with a photoresist layer and exposing and developing the photoresist layer to form an array of first openings over selected pixels; f) etching the silicon containing material, using the photoresist layer as a mask, to form an array of second openings in the layer of silicon containing material; g) etching the first colorant layer, using the layer of silicon containing material as a mask, to form an array of third openings in the first colorant layer; h) removing the photoresist layer; i) providing a second heat transferable colorant layer having heat transferable colorant materials on a third substrate and positioning the third substrate such that the heat transferable colorant layers are in transferable relationship with, but spaced apart from, the first substrate; j) heating the third substrate sufficiently to cause substantially all of the heat transferable colorant layers to transfer across the space so as to deposit the second colorant layers onto the layer of silicon containing material and into the third openings in the first colorant layers; k) removing the second colorant layers from non-selected regions leaving the second colorant layers in the third openings in the first colorant layers; and l) etching to remove the silicon containing material.
