Patent ID: 7507135

Claim:
A method of manufacturing a field emitter, the method comprising the steps of: forming a patterned conductive layer on a substrate; coating an exposed portion of the substrate and an upper surface of the patterned conductive layer with a mixture of a field emission material and metal powder; thermally treating the mixture to improve adhesion of the mixture to the patterned conductive layer; and removing a field emission material and a metal deposited on a portion of the substrate other than the patterned conductive layer; wherein the step of forming the patterned conductive layer comprises: forming a photoresist layer so as to expose an upper area of the substrate; coating the exposed upper area of the substrate and an upper surface of the photoresist layer with a conductive material; and forming a conductive layer by removing the photoresist layer and the conductive material coated on the photoresist; and wherein the step of thermally treating the mixture layer comprises thermally treating the mixture layer at a temperature of substantially 600° C. to increase adhesion between the mixture layer and the conductive layer.
