  • Publication number: 20100243046
    Abstract: Chalcogenide based photovoltaic devices cells with good resistance to environmental elements can be formed by direct low temperature deposition of inorganic barrier layers onto the film. A unique multilayer barrier can be formed in a single step when reactive sputtering of the silicon nitride onto an inorganic oxide top layer of the PV device.

  • Patent number: 6653741
    Abstract: A thermal interface material for use in electronic packaging, the thermal interface material comprises a solder with relatively high heat flow characteristics and a CTE modifying component to reduce or prevent damage due to thermal cycling. The thermal interface material comprises an active solder that contains indium and an intrinsic oxygen getter selected from the group consisting of alkali metals, alkaline-earth metals, refractory metals, rare earth metals and zinc and mixtures and alloys thereof. Lastly, damage due to an electronic package due to thermal cycling stress is reduced by using an insert in a lid of an electronic device package wherein the insert has a coefficient of thermal expansion that is between about that of the lid and about that of a semiconductor substrate.
