  • Publication number: 20040140748
    Abstract: An emitter has an electron supply layer and a silicon-based dielectric layer formed on the electron supply layer. The silicon-based dielectric layer is preferably less than about 500 Angstroms. Optionally, an insulator layer is formed on the electron supply layer and has openings defined within in which the silicon-based dielectric layer is formed. A cathode layer is formed on the silicon-based dielectric layer to provide a surface for energy emissions of electrons and/or photons. Preferably, the emitter is subjected to an annealing process thereby increasing the supply of electrons tunneled from the electron supply layer to the cathode layer.

  • Patent number: 6741016
    Abstract: An electron lens is used for focusing electrons from a cathode to an anode. The lens includes a first conductive layer with a first opening at a first distance from the cathode. The first conductive layer is held at a first voltage. The lens also includes a second conductive layer with a second opening at a second distance from the first conductive layer and a third distance from the anode. The second conductive layer is held at a second voltage substantially equal to the voltage of the anode. The first and second openings are chosen based on the first voltage, the second voltage, the first distance, the second distance and the third distance. The opening focuses the electrons emitted from the cathode onto the anode to a spot size preferably less than 40 nanometers. The force created between the cathode and anode is minimized by the structure of the lens.

  • Patent number: 6686642
    Abstract: An integrated circuit includes a substrate having an etched surface and a non-etched surface. The etched surface contains circuit elements and the non-etched surface contains a bonding surface. The non-etched surface is located at a predetermined height from the etched surface. Bonding this integrated circuit with another substrate creates a wide-gap between the substrates that is preferably evacuated and hermetically sealed.

  • Publication number: 20030141494
    Abstract: An emitter includes an electron source and a cathode. The cathode has an emissive surface. The emitter further includes a continuous anisotropic conductivity layer disposed between the electron source and the emissive surface of the cathode. The anisotropic conductivity layer has an anisotropic sheet resistivity profile and provides for substantially uniform emissions over the emissive surface of the emitter.

  • Patent number: 6336713
    Abstract: A high efficiency thermal inkjet printhead which uses a novel resistor system. The printhead includes a support structure, at least one layer of material which comprises at least one opening therethrough, and at least one ink expulsion resistor located within the printhead between the support structure and the layer of material having the opening therein. The resistor is produced from at least one metal silicon nitride composition. Numerous benefits are achieved by this development including (A) reduced resistor current consumption and greater energy efficiency; (B) increased bulk resistivity of the resistor elements compared with prior systems; (C) cooler printhead operation; (D) multiple economic benefits including the ability to use lesscostly, high voltage/low current power supplies; and (E) improved reliability, stability, and longevity levels in connection with the printhead and resistor elements.
