Method of manufacturing triode carbon nanotube field emitter array

摘要

A method of manufacturing a field emitter array using carbon nanotubes, low voltage field emission material, is provided. The method includes the steps of (a) forming a conductive thin film layer on the top of a transparent substrate having a transparent electrode and exposing a predetermined portion of the transparent electrode; (b) forming an opaque thin film layer on the exposed predetermined portion of the transparent electrode; (c) depositing an insulation material on the entire top surface of the transparent substrate and removing the insulation material from the top surfaces of the conductive thin film layer and the opaque thin film layer, thereby forming an insulation layer; (d) forming a gate layer on the top of the insulation layer; and (e) removing the opaque thin film layer and forming carbon nanotube tips on the top of the exposed transparent electrode. Accordingly, the triode carbon nanotube field emitter array can be easily manufactured using a small number of mask layers and without using a special aligner. <IMAGE>
