Abstract: A two-part field emission structure, and a method for making such a structure, is described. A substrate is provided having a first conductive layer thereon, a first insulating layer over the first conductive layer, a second conductive layer over the first insulating layer, and an opening formed in the first insulating and second conductive layers. A sacrificial layer is formed over the second conductive layer. A bottom portion of the field emitter structure is formed in the opening, by vertical deposition of a conductive material, whereby a third conductive layer, having a collimated channel over the bottom portion, is formed over the sacrificial layer. The formation of the field emitter structure is completed by vertical deposition of a tip material on to the top of the bottom portion of the field emitter structure, whereby a top conductive layer is formed over the third conductive layer. Lastly, the sacrificial layer, the third conductive layer, and the top conductive layer are removed. An optional interface adhesion layer is formed between the bottom portion of the field emitter structure and the tip.

Abstract: This invention provides a method of fabrication and structure for spacers between the anode substrate and the cathode substrate of a field emission display. The spacers have a high aspect ratio and which will be invisible to the human eye in the display image. An adhesive dielectric paste of glass frit in a binder is formed in cylindrical holes in a photoresist layer. Glass spacer spheres are placed on each column of dielectric paste. When fired the glass frit coalesces into a solid glass rod and bonds the glass spacer sphere to one end of the solid glass rod and the anode substrate to the other end of the solid glass rod. The firing also burns away the photoresist layer. The dark area in the image due to the spacers is less than 50 micrometers which will be invisible to the human eye.

Abstract: A high luminescence display, and methods for making such a display, are described. A faceplate for a display device having a glass face is provided, having phosphor elements on the glass face. There are reflective elements, on the glass face and adjacent to the phosphor elements, with surfaces angled toward the phosphor elements, whereby light emitted from the phosphor elements reflects off the reflective elements and travels through the glass face. The reflective elements may be formed of, for example, aluminum, and be directly adjacent to the phosphor, or offset from it.

Abstract: A new method for forming an anode plate for a color flat panel Field Emission Displays (FEDs) having improved gettering, was accomplished. The method involves forming on a transparent insulating plate (glass) an array of pixels of three phosphors comprising the primary colors and having in or/and around the array of pixels gettering material to provide more efficient gettering of volatile material from the FED cavity. The electrons are injected into the pixels when the electron field emitters are electrically accessed via the address and image forming circuits. The injected electrons heat and activate the gettering material in and around the pixels and provide very effective gettering in the FED cavity.

Abstract: Described are methods for making, and resultant structures of, a field emission display with soft luminescence and a comfortable image for a viewer of the display. The field emission display is formed with a baseplate and an opposing face plate. Field emission microtips are formed in openings in a conductive and insulating layer on the baseplate. An anode is formed on either the faceplate, or on the conductive layer surrounding each opening. Phosphorescent material is formed over the anode. A blocking layer is formed between the phosphor and the faceplate, such that during operation of the display direct light emission from the phosphor is blocked, resulting in indirect phosphorescence and a more comfortable display image. An optional reflective layer may be added over the conductive layer to increase phosphorescence.

Abstract: A method of forming a self-aligned gated field emitter with substantial manufacturing advantages is described. There is provided a substrate having at its surface a conductive layer. A first dielectric layer is deposited over the substrate. A conducting layer is deposited over the dielectric layer. Lithography and etching are used to form an opening through the conducting layer and the dielectric layer down to the surface of the substrate wherein there is formed an overhang of the conducting layer over the etched dielectric layer in the opening. Material is vertically deposited through the opening and over the conducting layer until the field emitter is formed and the opening is closed by build up of the depositing material over the conducting layer. At least a portion of the build up of the depositing material over the conducting layer is oxidized down to the desired opening size to form an oxide layer of the material. The oxide layer is removed by etching to expose the desired opening, thereby completing formation of the self-aligned gated field emitter.
