摘要:
A method (and apparatus) for nano lithography, includes applying a pneumatic pressure to at least one of a surface of a semi-rigid mask or template and a portion of a surface of a resist-coated workpiece, and, by the applying of the pneumatic pressure, transferring a pattern from the mask to the workpiece.

A convective method is employed to cool a solar concentrator device. The convective method employs formation of a vortex gas circulation inside an enclosure of the solar concentrator device, which is bounded by at least one light-path altering component, sidewalls, and a back panel. Optionally, a heat sink assembly can be provided within the enclosure. Internal convention through the vortex gas circulation transfers the heat generated at a photovoltaic cell to all surfaces of the solar concentrator device to facilitate radiative and/or convective cooling at the outside surfaces of the enclosure.

The present invention is an air/fluid cooling system. In one embodiment an apparatus for dissipating heat from a heat-generating device includes a base having a first side configured for thermal coupling to the heat-generating device, an air-based cooling path coupled to the base, for dissipating at least a portion of the heat via air, and a fluid-based cooling path coupled to the base, for dissipating at least a portion of the heat via a fluid. The air-based cooling path and the fluid-based cooling path may be operated simultaneously or individually to dissipate heat from the heat generating device and to allow access to the cooling system, for example for maintenance, repairs and upgrades.

A solar concentration system includes an optically clear shell member having an outer surface and an inner surface, with the inner surface defining a hollow interior portion, a liquid contained within the hollow interior portion of the optically clear shell, and a solar collection system contained within the hollow interior portion of the optically clear shell. The solar collection system includes a tracking system configured and disposed to selectively shift within the hollow interior portion, a reflector member mounted to the tracking system, and a solar receiver mounted to the tracking system. The tracking system being configured and disposed orient the reflector member and the solar receiver to follow a path of the sun enhancing the collection of solar energy.

Embodiments of an apparatus are described. This apparatus includes a semiconductor-die layer mechanically coupled to a semiconductor die, and a heat-removal-device layer mechanically coupled to a heat-removal device. Moreover, a thermal-interface material is included between the semiconductor die and the heat-removal device, where the thermal-interface material is mechanically coupled to a region of the semiconductor-die layer and to a region of the heat-removal-device layer. Additionally, a boundary material is mechanically coupled to the semiconductor-die layer and the heat-removal-device layer, where the thermal-interface material is contained in a cavity defined, at least in part, by the semiconductor-die layer, the boundary material, and the heat-removal-device layer.
摘要:
A process for forming a releasable metal film includes depositing a metal onto a polymeric sheet such that the metal layer provides a low adhesive interface and exhibits relatively low stress. A barrier layer is then deposited onto the surface of the low adhesion interface. A thin film of a stress relief layer of silicon dioxide, aluminum oxide, copper or aluminum is then deposited followed by addition of a second barrier layer onto the stress relief layer. The stress relief layer provides compressive relief to balance the tensile stress of the so-stacked metal films. An additional solderable layer maybe added for soldering applications. To fabricate the working device with sputtering tools, an extremely high gas pressure is used to achieve low adhesion force between the wettable metallic layer and the polymeric carrier film.
