摘要： A high resolution field emission display includes a faceplate and a baseplate. The faceplate includes a transparent viewing layer, a transparent conductive layer formed on the transparent viewing layer and intersecting stripes of light-absorbing, opaque insulating material formed on the transparent conductive layer. The insulating material defines openings less than one hundred microns wide between the intersecting stripes. The faceplate also includes a plurality of localized regions of cathodoluminescent material, each formed in one of the openings. The cathodoluminescent material includes a metal oxide providing reduced resistivity in the cathodoluminescent material. Significantly, the reduced resistivity of the cathodoluminescent material together with the focusing effect of the insulating material provide increased acuity in luminous images formed on the faceplate. The baseplate includes a substrate, an emitter formed on the substrate and a dielectric layer formed on the substrate and having an opening formed about the emitter. The baseplate also includes a conductive extraction grid formed on the dielectric layer and having an opening formed about the emitter.

摘要： A filtered cathodic vacuum arc is used as a source of metal to generate a highly directional beam of metal ions having substantially larger velocity parallel to the axis of the beam (perpendicular to the surface of the target) than perpendicular to the axis of the beam. This ion beam, with energies ranging up to 80 eV, is used to deposit metal into the bottom of high aspect (typically greater than 3 to 1) openings, for example, to deposit titanium in the bottom of deep contact holes in semiconductor devices or to deposit molybdenum to form tips for emitters for a field emission display. Gases can be introduced into the vacuum deposition chamber during deposition to change the nature of the deposit. The substrate or target bias can be adjusted to control the deposition rate.

摘要： A method for cleansing the phosphor screen of a display device comprising the removal of oxygen or sulfur from the surface of the phosphor, and/or its associated binder material, to a depth that prevents oxygen diffusion from the phosphor and/or binder, thereby creating an oxygen deficient surface on the phosphors.
