摘要:
A method of making a color filter array on a first substrate having an array of pixels, comprising the steps of: depositing and patterning a photoresist layer on the substrate layer to form selected openings over pixels in the array; providing a transferable colorant layer on a second substrate and positioning such transferable layer in transferable relationship with the first substrate; transferring the colorant material to the photoresist layer on the first substrate, removing the patterned photoresist layer by chemical mechanical polishing, leaving behind the colorant material in the position of the openings over the selected pixels.
