  • Patent number: 8101025
    Abstract: A method for controlling corrosion of a substrate is provided herein. In one embodiment, a method for controlling corrosion of a substrate includes the steps of providing a substrate having a patterned photoresist layer with a metallic residue disposed thereon; exposing the substrate to a hydrogen-based plasma to remove the metallic residue; and removing the photoresist. The metallic residue may comprise residue from etching at least one of aluminum or copper. The metallic residue may further comprise a halogen compound from etching a metal-containing layer with a halogen-based process gas. The hydrogen-based plasma may comprise hydrogen (H2) and may further comprise at least one of nitrogen (N2) and water (H2O) vapor. The hydrogen-based plasma may further comprise an inert gas, such as argon (Ar).

  • Patent number: 6582617
    Abstract: Provided is a method of etching an etch layer using a polycarbonate layer as a mask. The method includes placing an etch structure in a reaction chamber, the etch structure including an etch layer underlying a polycarbonate layer, the polycarbonate layer having apertures. The etch layer is then etched using a low-pressure high density plasma generate at a pressure in the range of approximately 1 to 30 millitorr where the ionized particle concentration is at least 1011 ions/cm3 and where the ionized particle concentration is substantially equal throughout the volume of the reaction chamber. To increase the etch rate, the etch structure can be cooled or biased. To decrease the etch rate, an inert gas can be added to the process gas mixture used to form the plasma.

  • Patent number: 6392750
    Abstract: Scattered or/and transmitted light is employed to determine characteristics, including dimensional information, of an object (60) such as part (10) of a flat-panel display. The dimensional information includes the average diameter of openings (62) in the object, the average density of the openings, and the average thickness of a layer (64) of the object. Light-diffraction patterns are produced to determine characteristics, such as abnormalities (146 and 148), of crossing lines (140 and 142) in such an object.

  • Patent number: 6356013
    Abstract: A flat panel display and a method for forming a flat panel display. In one embodiment, the flat panel display includes a wall which is held in place by a structure formed either on the faceplate or on the backplate. In one embodiment the supporting structure is formed by two adjacent walls that form a slot which mechanically restrains the wall. In another embodiment a slot is formed within the faceplate and the walls of the slot mechanically restrain the wall. In one embodiment wall segments are inserted into supporting structures that mechanically restrain each wall segment. In another embodiment a UV curable or a heat curable adhesive is used to maintain walls in their proper alignment and position. In yet another embodiment a conductive material is melted so as to bond conductive lines located on the wall and conductive lines located on the faceplate.

  • Patent number: 5578899
    Abstract: A field emission display device has a faceplate and a backplate. The faceplate includes a faceplate interior side with an active region made of a plurality of phosphor pixel elements; and the backplate has a backplate interior side with a plurality of field emitters. Sidewalls are positioned between the faceplate and the backplate, to form an enclosed sealed envelope between the sidewalls, backplate interior side and the faceplate interior side. At least one spacer wall in the envelope supports the backplate and the faceplate against forces acting in a direction toward the envelope. At least one internal structure fixes and constrains the faceplate and the backplate, and aligns a plurality of phosphor pixels with corresponding field emitters. Additionally, the faceplate can include at least one faceplate fiducial, and the backplate include a corresponding backplate fiducial. The faceplate fiducial is optically aligned with the backplate fiducial. First, the spacer wall is positioned in the wall gripper.
