    Abstract: Examples of novel semiconductor processing pedestals, and apparatuses including such pedestals, are described. These pedestals are specifically configured to provide uniform heat transfer to semiconductor substrates and to reduce maintenance complexity and/or frequency. Specifically, a pedestal may include a removable cover positioned over a metal platen of the pedestal. The removable cover is configured to maintain a consistent and uniform temperature profile of its substrate-facing surface even though the platen's upper-surface, which supports the cover and is in thermal communication with the cover, may have a much less uniform temperature profile. The cover may be made from certain ceramic materials and shaped as a thin plate. These materials are resistant to the processing environments and maintain their thermal characteristics over many processing cycles. The cover can be easily removed from the platen and replaced with a new one without a need for major disassembly of the entire apparatus.

  • Publication number: 20120142539
    Abstract: A novel method and structure for creating a high-temperature superconducting tape. The concept of the invention is to use a conductor insulation which not only electrically insulates the conductors of the coil windings from each other, but also mechanically insulates them from the much stronger encapsulant. The insulation material mechanically decouples the conductor from the encapsulant at the boundary between them, thereby preventing damage as a result of thermal and electromagnetic shearing forces. The proposed structure allows the encapsulant to continue performing its functions of preventing coarse motion and stabilizing the coil as a whole, while allowing fine relative displacements of individual coil windings caused by radial stress gradients.

  • Publication number: 20110197947
    Abstract: Provided are novel interconnect wire network assemblies and methods of fabricating thereof. An assembly may include conductive portions/individual wires that, in certain embodiments, are substantially parallel to each other. The assembly also includes two or more carrier films (i.e., the front side and back side films) attached to opposite sides of the wires. The films are typically attached along the wire ends. The films are made from electrically insulating materials and at least the front side film is substantially transparent. The front side film is used to attach the wires to a photovoltaic surface of one cell, while the back side film is used for attachment to a substrate surface of another cell. These attachments electrically interconnect the two cells in series. In certain embodiments, one or both carrier films extend beyond two end wires and form insulated portions that allow much closer arrangements of the cells in a module.

  • Publication number: 20100276055
    Abstract: Uncured thermosetting resins are loaded with relatively high amounts of solid thermoplastic resin particles to form a resin precursor. The resin precursor is heat treated so as to produce an uncured resin composition wherein the thermoplastic resin particles become substantially dissolved in the thermosetting resin without causing cure of the resin mixture. Heat treatment of highly loaded thermosetting resins in accordance with the present invention provides uncured resin compositions that are well suited for use in fabricating composite structures and particularly prepreg for use in lightning protection surface coatings.

  • Patent number: 7670643
    Abstract: An apparatus and method for dispensing a solution on a substrate is described in which the solution is dispensed through a solution nozzle assembly while the substrate is rotated. As the solution is dispensed, the solution on the substrate forms a wave front that radially spreads from the substrate center to the substrate edge. The dispensing of the solution is performed in such a way that the solution is dispensed at a radial location substantially equivalent to or less than the radial location of the wave front at any instant in time.

  • Patent number: 7670451
    Abstract: A cable is installed in coiled tubing for use in. downhole wells; the cable having an expandable jacket (22) extruded around it. After being installed in the coiled tubing, and the expandable jacket is caused to expand, securing the cable in the coiled tubing. The expandable jacket is caused to expand by the application of heat or by the application of a liquid hydrocarbon. The expandable jacket may be discontinuous along the length of the power cable, discontinuous portions being provided by interspersing the expandable jacket with sections non-expandable material.

  • Publication number: 20090280338
    Abstract: A method produces ferromagnetic core laminates for electrical machines. The core laminates have very thin layers of individual electrical strips which can be produced by a structure formed from layers of electrical strips. The electrical strips are connected by a connection layer, in particular an adhesive layer. This makes it possible to produce cores formed from layers of core laminate for electromagnetic machines, whose eddy-losses are reduced.
