A composition and method for fabricating high-density Ta&#x2014;Al&#x2014;O, Ta&#x2014;Si&#x2014;N, and W&#x2014;Si&#x2014;N sputtering targets, having particular usefulness for the sputtering of heater layers for ink jet printers. Compositions in accordance with the invention comprise a metal component, SiN, and a sintering aid so that the targets will successfully sputter without cracking, etc. The components are combined in powder form and pressure consolidated under heated conditions for a time sufficient to form a consolidated blend having an actual density of greater that about 95% of the theoretical density. The consolidated blend may then be machined so as to provide the final desired target shape.

A method of forming a micro-display includes forming a device that includes forming a partially reflecting layer on a first substrate and forming a plate overlying the partially reflecting layer, and adhering the device to a second substrate.

Micro-displays and their manufacture

A microelectromechanical device having a reset electrode for use in various devices including display devices such as those employing spatial light modulators. The device includes an optically transmissive substrate, a semiconductor substrate, and a member deflectable between a rest position and an operative position supported by one of the substrates. The deflectable member returns to an undeflected position by operation of the reset electrode.

Microelectromechanical device with reset electrode

A transparent active-matrix display based on a substrate has a multiplicity of transparent active pixel elements arranged in an array and transparent electrical connections to each pixel, whereby each of the pixel elements is adapted to be set independently to two or more states. In some embodiments, the substrate may also be transparent.

Transparent active-matrix display

A pixel device, comprising; a first plate, a second plate disposed under the first plate, and a third plate disposed under the second plate; a first power supply for providing a first voltage to the first plate; a second power supply for providing a second voltage to the second plate; and a third power supply for providing a third voltage to the third plate.

Pixel device

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.

Emitter and method of making

An ink-jet printhead is provided having a thin film substrate comprising a plurality of thin film layers; a plurality of ink firing heater resistors defined in said plurality of thin film layers; a polymer fluid barrier layer; and a carbon rich layer disposed on said plurality of thin film layers, for bonding said polymer fluid barrier layer to said thin film substrate.

An emitter has an electron supply layer and a tunneling layer formed on the electron supply layer. Optionally, an insulator layer is formed on the electron supply layer and has openings defined within in which the tunneling layer is formed. A cathode layer is formed on the tunneling 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.

Method of making a tunneling emitter

A re-recordable data storage medium is disclosed. The medium in one embodiment includes a phase-changeable layer and an intermediate layer. A junction between the intermediate layer and another layer of the medium provides a conduction barrier under no illumination that is substantially diminished under illumination of the regions of the phase-changeable layer that are in the appropriate phase.

A micro-mirror device includes a substrate, at least one electrode formed on the substrate, and a reflective element spaced from the substrate and extending beyond the at least one electrode. The reflective element is adapted to move between a first position and at least one second position, and, when the reflective element is in the at least one second position, a minimum distance between the reflective element and the at least one electrode is greater than a minimum distance between the reflective element and the substrate.

Micro-mirror device with increased mirror tilt

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 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.

Silicon-based dielectric tunneling emitter

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.

Multi-level integrated circuit for wide-gap substrate bonding

A re-recordable data storage medium of one embodiment includes a substrate layer, a phase-changeable layer, and an intermediate layer. The substrate layer has a semiconductor type selected from p-type and n-type. The phase-changeable layer has a first phase corresponding to a first storable logical value, and a second phase corresponding to a second storable logical value. The phase-changeable layer has a semiconductor type identical to that of the substrate layer. The intermediate layer is between the phase-changeable layer and the substrate layer, and has a semiconductor type opposite to that of the phase-changeable and substrate layer. The substrate, phase-changeable, and intermediate layers act as a transistor under selective illumination of the phase-changeable layer.
