Abstract: Bidirectional field emission devices (FEDs) and associated fabrication methods are described. A basic device includes a first unitary field emission structure and an adjacently positioned, second unitary field emission structure. The first unitary structure has a first cathode portion and a first anode portion, while the second unitary structure has a second cathode portion and a second anode portion. The structures are positioned such that the first cathode portion opposes the second anode portion so that electrons may flow by field emission thereto and the second cathode portion opposes the first anode portion, again so that electrons may flow by field emission thereto. A control mechanism defines whether the device is active, while biasing voltages applied to the first and second unitary structures define the direction of current flow. Multiple applications exist for such a bidirectional FED. For example, an FED DRAM cell is discussed, as are methods for fabricating the various devices.

Abstract: Lateral cathode field emission devices and methods of fabrication are set forth. Conventional integrated circuit fabrication techniques are advantageously used to produce the lateral FEDs. Cathode tips on the order of several hundred angstroms are consistently obtained as well as exact spacing of the cathode to gate and cathode to anode. Various cathode and device configurations are described, including a circular field emission device. A single integrated structure having multiple cathodes and multiple gates is possible to perform various logic operations and/or enhance current output from the device. Multiple field effect devices, with cathodes disposed parallel or perpendicular to the substrate, are integrally coupled through a sharing of one or more metallization layers definitive of the elements of the devices. Significant advantages in current density and circuit layout can be obtained. Methods for fabricating the various devices are also explained.

Abstract: A self-gettering electron field emitter has a first portion formed of a low-work-function material for emitting electrons, and it has an integral second portion that acts both as a low-resistance electrical conductor and as a gettering surface. The self-gettering emitter is formed by disposing a thin film of the low-work-function material parallel to a substrate and by disposing a thin film of the low-resistance gettering material parallel to the substrate and in contact with the thin film of the low-work-function material. The self-gettering emitter is particularly suitable for use in lateral field emission devices. The preferred emitter structure has a tapered edge, with a salient portion of the low-work-function material extending a small distance beyond an edge of the gettering and low resistance material. A fabrication process specially adapted for in situ formation of the self-gettering electron field emitters while fabricating microelectronic field emission devices is also disclosed.

Abstract: An electron field-emission display comprises one or more display cell structures, each having a field-emission cathode and an anode comprising at least one of several cathodoluminescent phosphors disclosed which are stimulable by electrons of very low energy. The display cell structures may also have gate elements for controlling electron current flowing from cathode to anode when suitable electrical bias voltages are applied. A preferred fabrication process integrates an etch stop with an in situ phosphor formation process. The etch stop precisely defines the depth of an opening in the display cell structure. Metal oxides or mixed-metal oxides of zinc, copper, tin, or indium are heated in the presence of a refractory metal such as titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, or combinations thereof to make phosphors of various chromaticities, which may also include dopants, such as a lanthanide rare earth element, manganese, chromium, or stoichiometrically excess zinc, copper, tin, or indium. A blue-light-emitting phosphor embodiment is based on ZnO treated with refractory metals, e.g. Ta, to prepare cathodoluminescent phosphor compositions, e.g. Ta.sub.2 Zn.sub.3 O.sub.8. Selective arrangement of various color phosphors may be made by selective deposition of suitable dopants. The selective deposition may be done, e.g. by chemical vapor deposition with appropriate masking, or by selective ion implantation.
