Abstract: A field emission cathode for use in flat panel displays is disclosed comprising a layer of conductive material and a layer of amorphic diamond film, functioning as a low effective work-function material, deposited over the conductive material to form emission sites. The emission sites each contain at least two sub-regions having differing electron affinities. Use of the cathode to form a computer screen is also disclosed along with the use of the cathode to form a fluorescent light source.

Abstract: A maskless process for forming a protected metal feature in a planar insulating layer of a substrate is disclosed. A first barrier material is disposed in a recess in an insulating layer, a conductive metal is disposed on the first barrier material such that the entire metal feature is positioned within the recess below the top of the recess, a second barrier material is disposed on the metal feature such that the second barrier material occupies the entire portion of the recess above the metal feature and extends above the top surface of the insulating layer, and the second barrier material is then polished until the top of the second barrier material is in and aligned with the top of the insulating layer. As a result, the metal feature is surrounded and protected by the first and second barrier materials, and the substrate is planarized.

Abstract: An improved coating for optical fibers is described. The present invention is a dimensionally precise and uniform coating with low-porosity. The improved coating is applied via sputtering within a vacuum chamber. Environmental conditions are monitored within a cylindrical magnetron during sputtering. Sputtering is adjusted or temporarily ceased when environmental conditions approach a damage threshold. Sputtered particles within a plasma cloud are dimensionally similar and adhere to an optical fiber in a volume efficient arrangement forming a more precise, denser, and more adherent coating. Embodiments of the present invention provide improved pull strength by compressively constraining the optical fiber within the coating and by closing microcracks.

Abstract: A device for testing flat panel displays includes an interface having compliant bumps mounted thereon, which make electrical contact with pads on the display panel. The interface may have a hole formed therein for allowing the passage of light therethrough when the interface is mounted on the display panel. The compliant bumps ensure that all of the bumps make sufficient electrical contact with the pads.
