  • Publication number: 20240154188
    Abstract: Provided are battery packs and interface modules for electrically interconnecting electrochemical cells in the packs and for providing heat distribution with the packs. An interface module interfaces one side of all electrochemical cells in a battery pack. The interface module may have a substantially planar shape such that the space occupied by the module in the battery pack is minimal. Most, if not all, conductive components of the interface module may be formed from the same sheet of metal. In some embodiments, the interface module includes multiple bus bars such that each bus bar interconnects two or more terminals of different electrochemical cells in the battery pack. Each bus bar may have a separate voltage sense lead extending from the bus bar to a connecting portion. The bus bars may be flexibly supported within the module. The interface module may also include multiple thermistors disposed on different bus bars.

  • Patent number: 6746198
    Abstract: The present invention provides an apparatus and method for substrate transport. In systems according to the invention, at least a first and second chamber are provided. The first chamber may be a load lock and the second chamber a processing chamber. A substrate transfer shuttle is provided and is moveable along a linear path defined by guide rollers between one position in the first chamber and another position in the second chamber. In this way, the substrate may be transferred, in both a forward and a reverse direction, between the first chamber and the second chamber. The substrate transfer shuttle is structured so that a substrate may be removed therefrom by moving a support in one of the chambers from a lowered position to an intermediate position, after which the substrate transfer shuttle may be removed from the chamber.

  • Patent number: 5676803
    Abstract: A target, target backing plate, and cover plate form a target plate assembly. The sputtering target assembly includes an integral cooling passage. A series of grooves are constructed in either the target backing plate or the target backing cooling cover plate, which are then securely bonded to one another. The sputtering target can be a single monolith with a target backing plate or can be securely attached to the target backing plate by one of any number of conventional bonding methods. Tantalum to titanium, titanium to titanium and aluminum to titanium, diffusion bonding can be used.The target plate assembly completely covers and seals against a top opening of a sputtering processing chamber. Cooling liquid connections are provided only from the perimeter of the target assembly. When a top vacuum chamber seals the side opposite the pressure chamber, the pressure on both sides of the target assembly is nearly equalized.

  • Patent number: 5611865
    Abstract: Centering pins mounted to a susceptor in a vacuum chamber align a glass substrate with respect to the susceptor on which it is supported, and with respect to a shadow frame which overlies the periphery of the substrate and protects the edge and underside of the substrate from undesired processing.Shaped pins loosely mounted in openings in the susceptor so that the pins extend above the upper surface of the susceptor support the centered glass substrate during the transporting stages, but recess into the heated susceptor during processing.
