    Abstract: A field emitter cell includes a thin film edge emitter normal to a gate layer. The field emitter is a multilayer structure including a low work function material sandwiched between two protective layers. The field emitter may be fabricated from a composite starting structure including a conductive substrate layer, an insulation layer, a standoff layer and a gate layer, with a perforation extending from the gate layer into the substrate layer. The emitter material is conformally deposited by chemical beam deposition along the sidewalls of the perforation. Alternatively, the starting material may be a conductive substrate having a protrusion thereon. The emitter layer, standoff layer, insulation layer, and gate layer are sequentially deposited, and the unwanted portions of each are preferentially removed to provide the desired structure.

    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 low turn-on voltage volcano-shaped field emitter, a method of fabrication, and integration into an addressable array suitable for applications in field emitter displays and other electron generating applications are disclosed. In one embodiment, the device is fabricated using a stepped insulator in which the distance between the gate and the emitter near the emission surface is significantly reduced with respect to the thickness of the insulator and separates the gate from the emitter. By keeping the large gate-to-emitter distance, the device capacitance is reduced and fabrication yield is increased, since pinholes in the insulator are significantly reduced. In another embodiment of the present invention, the integration of the device into an addressable array suitable for electron emission is described. The array incorporates a network of resistors which assures uniform emission.

    Abstract: A lateral-emitter electron field-emission display device structure incorporates a thin-film emitter having an emitting edge and extending into in direct contact with a non-conducting or very high resistivity phosphor, thereby eliminating the gap between the emitter and the phosphor. Such a gap has been a part of all field-emission display devices in the prior art. The ultra-thin-film lateral emitter of the new structure is deposited in a plane parallel to the device's substrate and has an inherently small radius of curvature at its emitting edge. A fabrication process specially adapted to make the new structure includes a directional trench etch, which both defines the emitting edge and provides an opening to receive a non-conducting phosphor. This phosphor covers an anode and is automatically aligned in contact with the emitter edge. When an electrical bias voltage is applied between the emitter and anode, electrons are injected directly into the phosphor material from the emitter edge, exciting cathodoluminescence in the phosphor to emit light which is visible in a wide range of viewing angles. With minor variations in the fabrication process, a lateral-emitter electron field emission display device may be made with an extremely small emitter-phosphor gap, having a width less than 100 times the thickness of the ultra-thin emitter. Embodiments in which the gap width is zero are characterized as edge-contact light-emitting diodes (or triodes or tetrodes if they include control electrodes).
