Abstract: A field emission cold cathode sends forth uniform emission over the entire emission area and realizes, when applied to a flat screen display device and the like, a uniform brightness of images over the entire display area, providing a high quality field emission type cold cathode. An electron tube is equipped with the cold cathode. The cold cathodes structurally prevent a prolonged electric discharge with the use of trenches. Non-uniformity of resistance, resulting from the difference in extension of the depletion regions in each block divided by the trenches, can be prevented by an arrangement of blocks in which each block divided by trenches is placed to have a prescribed distance from an adjacent block, which makes emission currents in all blocks within the formed emitter area uniform at the time of normal operation, and thereby a good form in which depressions in the block corner sections are well suppressed can be obtained.

Abstract: The invention relates to the structure of a field emitter device, to the method of fabricating a field emitter device and to the use of the field emitter device in the technical field of flat panel displays. The field emission device comprises an array (1) of widely-spaced tips (2) for emitting electrons and a perforated extracting electrode (3) facing the array of tips. An individual series resistor is formed by each of said tips itself. The widely-spaced tips are not surrounded by a layer of electrically insulating material. The tips are not surrounded by an insulating layer and the tip end is not surrounded by a gate or extraction electrode. This avoids failures like shorts between the cathode electrode and the gate or extraction electrode which could occur due to inaccurate coating or etching processes, and enhances the reliability and the life-time of the array of tips. To fabricate the field emission device, a micromechanically manufactured array (1) of widely-spaced tips (2) and a micromechanically manufactured perforated extracting electrode (3) are provided. The outer sides of the perforated extracting electrode are bonded to the array in a way that the perforated extracting electrode is facing the array. With the array of widely-spaced tips and the perforated extracting electrode being fabricated separately and bonded together subsequently, both the number of process steps required for each of the two parts and the manufacturing process costs are reduced.

Abstract: A cold cathode field emission display is described. A key feature of its design is that each individual microtip has its own ballast resistor. The latter is formed from a resistive layer that has been interposed between the cathode line and the substrate. When openings for the microtips are formed in the gate line, extending down as far as the resistive layer, an overetching step is introduced. This causes the dielectric layer to be substantially undercut immediately above the resistive layer thereby creating an annular resistor positioned between the gate line and the base of the microtip.

Abstract: Rod-shaped or cylindrical structures in the nm range on a substrate of silicon are manufactured. A first cylinder of silicon is selectively epitaxially deposited in the hole of a mask layer of oxide, and the mask layer is removed. The silicon is then oxidized to form an oxide layer having such a thickness that a thinner, second cylinder of silicon having practically the same height as the first cylinder remains. In a last step, this oxide layer is removed, so that the second cylinder forms a freestanding silicon rod on the surface of the substrate.

Abstract: Diamond microtip field emitters are used in triode vacuum microelectronic devices, sensors and displays. Diamond triode devices having integral anode and grid structures can be fabricated. Ultra-sharp tips are formed on the emitters in a fabrication process in which diamond is deposited into mold cavities in a two-step deposition sequence. During deposition of the diamond, the carbon graphite content is carefully controlled to enhance emission performance. The tips or the emitters are treated by post-fabrication processes to further enhance performance.

Abstract: A manufacturing method for a field emission display includes the steps of (1) forming a conductive film on a substrate that is to be a base plate, the conductive film being for forming a cathode electrode; (2) applying, on the conductive film, a positive resist, which is a photosensitive material; (3) exposing the positive resist to light, so as to form openings that correspond in a shape of emitters, the light being (a) emitted from a light source, (b) paralleled so that rays thereof have even light intensity distribution, and (c) directed into a micro lens array so as to be condensed in interior of the photosensitive material; and (4) forming the emitters respectively in the openings. This arrangement provides a manufacturing method for a field emission display, the method capable of highly accurately and highly productively sharp emitters aligned orderly, without a complicate manufacturing step and a complicate optical system.
