Abstract: Gated electron emitters are fabricated by processes in which charged particles are passed through a track layer (24, 48, or 144) to form charged-particle tracks (26.sub.1, 50.sub.1, or 146.sub.1). The track layer is etched along the tracks to create open spaces (28.sub.1, 52.sub.1, or 148.sub.1). Electron-emissive elements (30 or 142D) can then be formed at locations respectively centered on the open spaces after which a patterned gate layer (34B, 40B, or 158C) is provided. Alternatively, the open spaces in the track layer can be employed to etch corresponding apertures (54.sub.1) through an underlying non-insulating layer (46) which typically serves as the gate layer. An etch is performed through the apertures to form dielectric open spaces (56.sub.1, 96.sub.1, or 114.sub.1) in an insulating layer (24) that lies below the non-insulating layer. Electron-emissive elements (30B, 30/88D.sub.1, 98/102.sub.1, or 118.sub.1) can subsequently be provided, typically in the dielectric open spaces.

Abstract: A flat panel image sensor is provided by combining the photoconductive imaging electrode of a vidicon with a two dimensional array of cold cathode field emitters commonly used for flat panel Field Emission Display (FED) systems. The FED operates normally to emit electrons which are accelerated in prior art displays towards a luminescent phosphor to generate light output proportional to the cathode emission. Rather than accelerating towards a phosphor, electrons, in accordance with the principles of this invention, are accelerated towards a photoconductor layer to replace charge removed from the layer by an incident radiation pattern directed at the photoconductor layer through a layer of transparant, electrically-conducting material which serves as a radiation window. A large area, low cost, small, flat panel sensor is realized. The transparant, electrically-conducting layer may be partitioned to reduce stray capacitance for large area sensors and the partitioned, electrically-conducting layer permits a parallel readout mode of operation. The sensor includes a means for collimating and focusing the electron beams and may be used with infra red and ultra violet photoconductor materials.

Abstract: Electron excited luminous element capable of ensuring satisfactory emission characteristics of emitters for an extended period of time. A hydrophobic insulating film is formed on a glass anode substrate so as to cover an exposed portion thereof between anode electrodes. This keeps the glass anode substrate from being directly attacked by electrons, to thereby prevent decomposition of water and the like contained in a surface of the glass, resulting in oxygen which causes deterioration in emission characteristics of emitter cones being kept from being released from the glass.

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 field emission device (100) uses single crystals in order to eliminate grain boundaries within some or all of the electrodes (103, 104, and 205). The elimination of grain boundaries reduces susceptibility to damage, improves stability of the device (100), and improves uniformity and reproducibility among devices. In a preferred embodiment, the emitter and gate electrodes (103 and 104 respectively) are formed from a single crystal thin film (302). In other embodiments, other structures are employed wherein one or more of the electrodes (103, 104, and 205) are formed from single crystals.
