    摘要: A gas discharge illumination device is prepared by encapsulating ionizable gas within microporous or nanoscale sealed cavities created within a matrix material. Upon exposure of said matrix material to an electric field, the ionizable gas becomes ionized and emits light. By incorporating several different ionizable gases into one matrix material, a display with different colors of light can be produced. The gas discharge illumination device can be fabricated by a variety of techniques including selective cavity formation with overcoating taking place in an ionizable gas ambient, and bubbling ionizable gas through the matrix material while it is in viscous form. The gas discharge illumination device can be used to form either active or passive displays, as a sensor for detecting electric fields, and in other applications.

    摘要: A method of forming inter-level contacts or vias between metal layers using a tungsten film deposited into the via using non-collimated sputter deposition. The sputter chamber is configured with a pressure of about 1 mTorr to about 10 mTorr with an inert gas flow of at least at least 25 cm3/min to about 150 cm3/min. Shielding inside the chamber is coated with a material, preferably, aluminum oxide, that promotes adhesion of tungsten to the shielding. An adhesion layer of titanium may be included prior to deposition of the tungsten film. Non-collimated sputter deposition increases the target to substrate distance inside the sputter chamber; reduces the heating effect associated with traditional collimated sputtering; and provides more robust diffusion barriers.

    摘要: Bidirectional field emission devices (FEDs) and associated fabrication methods are described. A basic device includes a first unitary field emission structure and an adjacently positioned, second unitary field emission structure. The first unitary structure has a first cathode portion and a first anode portion, while the second unitary structure has a second cathode portion and a second anode portion. The structures are positioned such that the first cathode portion opposes the second anode portion so that electrons may flow by field emission thereto and the second cathode portion opposes the first anode portion, again so that electrons may flow by field emission thereto. A control mechanism defines whether the device is active, while biasing voltages applied to the first and second unitary structures define the direction of current flow. Multiple applications exist for such a bidirectional FED. For example, an FED DRAM cell is discussed, as are methods for fabricating the various devices.
