摘要： In accordance with the invention, a field emission device is made by disposing emitter material on an insulating substrate, applying a sacrificial film to the emitter material and forming over the sacrificial layer a conductive gate layer having a random distribution of apertures therein. In the preferred process, the gate is formed by applying masking particles to the sacrificial film, applying a conductive film over the masking particles and the sacrificial film and then removing the masking particles to reveal a random distribution of apertures. The sacrificial film is then removed. The apertures then extend to the emitter material. In a preferred embodiment, the sacrificial film contains dielectric spacer particles which remain after the film is removed to separate the emitter from the gate. The result is a novel and economical field emission device having numerous randomly distributed emission apertures which can be used to make low cost flat panel displays.

摘要： The disclosed multi-pixel flat panel displays (e.g., flat panel field emission displays (FPFED) or liquid crystal displays (LCD)) includes spaced apart first and second electrodes, with a patterned solid material layer in contact with one of the electrodes, exemplarily between the two electrodes. The patterned layer (referred to as the "web") includes a multiplicity of apertures, with at least one (preferably three or more) aperture associated with a given pixel. In the aperture is disposed a quantity of a second material, exemplarily, a phosphor in the case of an FPFED, or a color filter material in the case of a LCD. The web can facilitate second material deposition by means of, e.g., screen printing, typically making possible formation of smaller phosphor or filter dots than was possible by prior art device. The web also can facilitate provision of spacer structure between the two electrodes, and can include getter or hygroscopic material.

摘要： The present invention provides improved techniques for metallizing ceramic substrates. The method comprises providing a ceramic substrate and depositing a layer of reducible material on the ceramic substrate. The layer of reducible material includes a reducible ceramic such as copper oxide. The ceramic substrate having the layer of reducible material disposed thereon is heated and the reducible material is contacted with a reducing agent to create a conductive region. The conductive region is either a metallized region formed by reduction, or it is a conductive ceramic formed through surface reduction. The present invention further provides a metallized ceramic substrate. The metallized layer comprises ceramic regions having at least one constituent in common with the ceramic substrate. The ceramic substrate and the ceramic regions of the metallized layer are sintered to each other such that the metallized region is interspersed between the sintered ceramic regions. In this fashion, the metal is firmly held to the ceramic substrate due to the presence of the bonded ceramic within the metallized layer.

摘要： A ferrite layer formation process that may be performed at a lower temperature than conventional ferrite formation processes. The formation process may produce highly anisotropic structures. A ferrite layer is deposited on a substrate while the substrate is exposed to a magnetic field. An intermediate layer may be positioned between the substrate and the ferrite to promote bonding of the ferrite to the substrate. The process may be performed at temperatures less than 300° C. Ferrite film anisotropy may be achieved by embodiments of the invention in the range of about 1000 dyn-cm/cm3 to about 2×106 dyn-cm/cm3.

摘要： Devices are described which utilize a low loss dielectric material. This dielectric material is unique in that it combines low dielectric loss with a high and temperature-stable dielectric constant. The material is made up of BaO and TiO.sub.2 and corresponds closely in composition to the compound Ba.sub.2 Ti.sub.9 O.sub.20. Devices utilizing this material are useful at a variety of frequencies, but are particularly advantageous in the microwave region above 0.5 GHz.

摘要： An inductor (100) optimized for surface-mount vacuum-pickup automated circuit assembly eliminates the expense of an inductor housing. The inductor has a hollow rectangular ferrite core (101) and a winding defined by a stripline (102) deposited on the core surface. Winding ends are formed by conductive vias (103) in the core that open onto the core surface, where they connect and mount the inductor to a circuit board (150). A flat sheet (104) adhered to one face of the core provides a surface for vacuum pickup and for labeling of the inductor. The core of a passively tuneable inductor (200) defines multiple unconnected winding segments (102-103). Segment ends mount the inductor to the circuit board and connect the segments to circuit board striplines (254) that are laid out in a pattern to interconnect a number of the segments into a winding. The inductor is tuned by changing the stripline layout and thereby varying the number of interconnected segments. The core of an electromagnetic interference choke (300) defines two windings wound axially in parallel and radially in opposite directions. The core of a choke (500) that permits stacked mounting defines additional conductive vias (503) for connecting the windings of a second choke (300) mounted on the core to the circuit board. For electromagnetic isolation, the windings of the two chokes are oriented orthogonally to each other.
