Abstract:
A film (705) (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing etching of a substrate (701) and then depositing the film. The etching step creates nucleation sites on the substrate for the film deposition process. With this process patterning of the emitting film is avoided. A field emitter device can be manufactured with such a film. A metal film can also be deposited (702), patterned by photolithography (703) and etch (704) to prepare nucleation sites.
Abstract:
A film (carbon and/or diamond) for a field emitter device, which may be utilized within a computer display, is produced by a process utilizing etching of a substrate (704) and then depositing the film (705). The etching step creates nucleation sites on the substrate for the film deposition process. With this process patterning of the emitting film is avoided. A field emitter device can be manufactured with such a film. A field emission device results where the cathod has a continuous film that has not been subjected to etching, and thus has superior emission properties. A pixel in the cathode includes the emitting film deposited directly on the substrate with the conductor deposited on one or more sides of the emitter film. In one embodiment the emitter is in a window formed in the conductor layer.
Abstract:
A carbon film (101) having an area of insulating material surrounded by an area of conducting material, and an area of material between the insulating material and the area of conducting material having a graded dielectric constant which varies from high to low from the area of insulating material to the area of conducting material.
