    Abstract: A field emission cold cathode structure has an insulation layer having two-dimensional arrays of cavities, with a gate electrode on the insulation layer and two-dimensional arrays of opening portions having a generally circular shape positioned over the cavities. Field emission cold cathodes within the cavities each has a cone-like shape with a pointed top. The tops of the field emission cold cathodes are off-center within the opening portions in horizontal directions toward a reference point positioned on the gate electrode, and the distances of the tops from centers of the opening portions are varied to increase in accordance with increase in distance of the field emission cold cathodes from the reference point. This causes deflections of electron beams emitted from the tops of the field emission cold cathodes toward a concentration point which is positioned on a line extending from the reference point in a vertical direction to a surface of the gate electrode.

    Abstract: An improved high-frequency field-emission microelectronic device (10) has a substrate (20) and an ultra-thin emitter electrode (30) extending parallel to the substrate and having an electron-emitting lateral edge (110) facing an anode (40) across an emitter-to-anode gap (120). A control electrode (70), having a lateral dimension only a minor fraction of the emitter-to-anode gap width, is disposed parallel to the emitter and spaced apart from the emitter by an insulator (60) of predetermined thickness. A vertical dimension of the control electrode is only a minor fraction of the height of the anode. The control electrode may substantially surround a portion of the anode, spaced from the anode in concentric relationship. Inter-electrode capacitance between the emitter and the control electrode has only an extremely small value, consisting of only a very small area term and a very small fringing-field term, thus allowing operation of the microelectronic device at higher frequencies or switching speeds than heretofore. Inter-electrode capacitance between the control electrode and the anode also has only an extremely small value, thus improving higher frequency performance further. Devices having a plurality of control electrodes may also be made with improved inter-electrode capacitance.

    Abstract: A an electron source utilizes a novel extraction grid conductor (20,40,41) to assist in focusing an electron beam emitted by the electron source. The extraction grid conductor (20,40,41) has a collimating conductor (29,31) that separate an extraction grid section (17,21,22) of the extraction grid conductor from conducting strips (26,24,32,33) that electrically connect the extraction grid section (17,21,22) to an external voltage source. The collimating conductor (29,31) creates an electric field that prevents emitted electrons from being attracted to the conducting strips (26,24,32,33) thereby maintaining the emitted electron beam in a substantially column-like configuration.

    Abstract: A method of forming a self-aligned gated field emitter with reduced gate opening and uniform gate height, on a substrate, is described. A field emitter is formed on the substrate. A thin, conformal dielectric layer is formed over the field emitter and the substrate. A thick dielectric layer is formed over the thin, conformal dielectric layer. The thick dielectric layer is planarized. The thick dielectric layer is etched back. A conductive layer is formed over the thick dielectric layer. The conductive layer is planarized and then etched back. The field emitter is exposed by forming an opening in the conductive layer, by removing the portion of the thin, conformal dielectric layer above and around the top of the field emitter.
