  • Patent number: 5874188
    Abstract: A method of making a color filter array of uniformly thick organic pigments on a first substrate includes coating an adhesion promoting layer over the first substrate; coating the adhesion promoting layer with an intermediate layer; coating the intermediate layer with a photoresist layer; and exposing and developing the photoresist layer to form an-array of first openings. The substrate further includes etching the intermediate layer, using the photoresist layer as a mask, to form an array of second openings in the intermediate layer which are wider than the corresponding first openings in the photoresist layer; depositing an organic pigment layer on the photoresist layer; lifting off the photoresist layer and overlying organic pigment layer; and removing the intermediate layer, leaving the organic pigment layer in the position of the second openings.
