摘要： A method for creating emitters of a field emission device is provided. First, a hardmask layer is deposited on a substrate used to form emitters. On the hardmask layer, a photoresist layer is deposited. Islands of photoresist are exposed by an exposing energy through holes in a mask layer. The mask layer is removed and the substrate soft-baked in an oven having an atmosphere of basic gas. Following the soft-bake, the substrate is flood exposed, and then developed using conventional means, leaving behind hardened islands of exposed and baked photoresist. The hardmask layer is etched using the hardened islands as an etching barrier, and the substrate etched with a chemical etchant using the etched hardmask layer as an etching barrier. The etching continues until the substrate material below the etched hardmask layer is formed into an array of points of substrate. Once these emitter sites are formed, a field emission display having uniform emitters can be created.

摘要： A field emission display with raised conductive features at bonding locations, and methods of forming the raised conductive features. In accordance with one embodiment of the invention, a plurality of applicators are arranged in a pattern corresponding to a pattern of bonding locations on either a baseplate or a faceplate of a field emission display. The bonding locations and respective applicators are aligned with each other, and then a predetermined quantity of a thick film conductive bonding material is deposited substantially simultaneously through each applicator onto each bonding location. The thick film conductive bonding material forms a conductive pad at each bonding location. The pads of thick film conductive bonding material are subsequently fired to form a raised feature at each bonding location.

摘要： A method of forming a surface conduction electron emitter is as follows. A first electrode and a second electrode are provided on a surface. The first and second electrodes are separated by a gap. A composition comprising particles and carrier material is provided over the surface. A portion of the composition that is over the surface is within the gap, and another portion of the composition that is over the surface is over the electrodes. The composition is exposed to a pattern of radiation to render the portion of the composition within the gap less soluble in a solvent than the portion of the composition that is over the electrodes. The composition is exposed to the solvent to remove an entirety of the portion of the composition that is over the electrodes while leaving the portion of the composition that is within the gap.

摘要： A field emission display has an anode with a grille made at least in part of a getter material. The grille defines regions that are coated with phosphor to form pixels, and also getters free molecules within a sealed display. The getter material can alternatively be formed directly on at least a part of the grille, or over the grille on an intermediate layer.

摘要： The present invention provides an FED with a getter material deposited and activated on the substrates of the faceplate and the baseplate of the FED. In one embodiment of the invention, a large FED includes a faceplate, a baseplate, and an unactivated non-evaporable getter material. The faceplate has a transparent substrate with an inner surface, and a cathodoluminescent material disposed on a portion of the inner surface. The baseplate has a base substrate with a first surface and an emitter array formed on the first surface. The baseplate and the faceplate are coupled together to form a sealed vacuum space in which the inner surface and the first surface are juxtaposed to one another in a spaced-apart relationship across a vacuum gap. The unactivated non-evaporating getter material is deposited directly on the inner surface and/or the first surface. The unactivated non-evaporating getter material may alternatively be deposited on a thin film of bonding material that is disposed on the inner surface and/or the first surface.
