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: A microelectronic light-emitting device (10) is made with dual lateral thin-film emitters (35 and 40) substantially parallel to a substrate (20). Emitter electrodes (35 and 40) have a thickness of not more than several hundred angstroms. Each emitter has an emitting blade edge (110 or 115) having a small radius of curvature. Thus, opposed emitters for two opposite-sign carriers are provided, shaped to provide very high electric field intensity at their emitting tips. A region containing phosphor (50) extends between the two emitters and contacts them. When a suitable bias voltage is applied, electrons are injected into the phosphor from the blade edge of one emitter and holes are injected from the other emitter. The sum of diffusion lengths of the carriers (including secondary carriers) is equal to or greater than the shortest distance between the emitters. DC, AC, pulsed, or other voltage waveforms can be applied. Light emission is excited from the phosphor by carrier recombination. Devices may be combined in a matrix display array, and/or combined to form a super-pixel, and/or combined to form segments of a character display.

Abstract: A field emission device (10) is made with a lateral emitter (100) substantially parallel to a substrate (20) and with a simplified anode stucture (70). The lateral-emitter field-emission device has a thin-film emitter cathode (100) which has a thickness not exceeding several hundred angstroms and has an emitting blade edge or tip (110) having a small radius of curvature. The anode's top surface is precisely spaced apart from and below the plane of the lateral emitter and receives electrons emitted by field emission from the blade edge or tip of the lateral-emitter cathode, when a suitable bias voltage is applied. A fabrication process is disclosed using process steps (S1-S18) similar to those of semiconductor integrated circuit fabrication to produce the novel devices and their arrays. Various embodiments of the fabrication process allow the use of conductive or insulating substrates (20) and allow fabrication of devices having various functions and complexity. The anode (70) is simply fabricated, without the use of prior-art processes which formed a spacer made by a conformal coating. In a preferred fabrication process for the simplified anode device, the following steps are performed: an anode film (70) is deposited; an insulator film (90) is deposited over the anode film; an ultra-thin conductive emitter film (100) is deposited over the insulator and patterned; a trench opening (160) is etched through the emitter and insulator, stopping at the anode film, thus forming and automatically aligning an emitting edge of the emitter; and means are provided for applying an electrical bias to the emitter and anode, sufficient to cause field emission of electrons from the emitting edge of the emitter to the anode. The anode film may comprise a phosphor (75) for a device specially adapted for use in a field emission display. The fabrication process may also include steps to deposit additional insulator films (130) and to deposit additional conductive films for control electrodes (140), which are automatically aligned with the emitter blade edge or tip (110).

Abstract: A lateral field emission device and method of fabricating the device which maximizes gate control of the cathode emitter electric field strength is disclosed. Gate control increases when the position of the gate edge is optimized with respect to the position of the emitter tip. Maximum control is achieved if the gate extends a distance beyond the emitter in the direction of the anode. Preferably, the displacement of the gate edge from the emitter tip is one half the cathode tip-anode distance for optimum control. The high gain device of the present invention provides improved transconductance.

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. The display cell structures may also have one or more gate elements for controlling electron current flowing from cathode to anode when suitable electrical bias voltages are applied.

The phosphors are preferably prepared in situ in an electrically-conductive thin-film or surface-layer form during fabrication of the display. A preferred fabrication process integrates an etch stop with the in situ phosphor process, the etch stop precisely defining 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.
