  • Publication number: 20140256128
    Abstract: Method and apparatus for reducing metal oxide surfaces to modified metal surfaces are disclosed. By exposing a metal oxide surface to a remote plasma, the metal oxide surface on a substrate can be reduced to pure metal and the metal reflowed. A remote plasma apparatus can treat the metal oxide surface as well as cool, load/unload, and move the substrate within a single standalone apparatus. The remote plasma apparatus includes a processing chamber and a controller configured to provide a substrate having a metal seed layer in a processing chamber, form a remote plasma of a reducing gas species where the remote plasma includes radicals, ions, and/or ultraviolet (UV) radiation from the reducing gas species, and expose a metal seed layer of the substrate to the remote plasma to reduce oxide of the metal seed layer to metal and to reflow the metal.

  • Publication number: 20140240883
    Abstract: Apparatuses and methods for protecting a circuit from an over-limit electrical condition are disclosed. One example apparatus includes a protection circuit coupled to a circuit to be protected. The circuit to be protected is coupled to a pad node. The protection circuit is configured to conduct current from the pad node to a reference voltage node to protect the circuit from an over-limit electrical condition. The protection circuit has a trigger circuit coupled to the pad node and configured to trigger a shunt circuit to conduct current from the pad node to the reference voltage node responsive to a voltage provided to the pad node having a voltage exceeding a trigger voltage. In some embodiments, the trigger circuit is matched to the circuit being protected.

  • Publication number: 20140197037
    Abstract: A method of treating a copper containing structure on a substrate is disclosed. The method includes electrodepositing the copper containing structure on a substrate, annealing the copper containing structure, and forming an interface between a pad of the copper containing structure and a solder structure after anneal. The interface can have improved resistance to interfacial voiding. The copper containing structure is configured to deliver current between one or more ports and one or more solder structures in the integrated circuit package. Annealing the copper containing structure can move impurities and vacancies to the surface of the copper containing structure for subsequent removal.

  • Patent number: 8741728
    Abstract: Methods, systems, structures and arrays are disclosed, such as a resistive memory array which includes access devices, for example, back-to-back Zener diodes, that only allow current to pass through a coupled resistive memory cell when a voltage drop applied to the access device is greater than a critical voltage. The array may be biased to reduce standby currents and improve delay times between programming and read operations.

  • Patent number: 8667683
    Abstract: Apparatus and methods for use with a baffle support fixture for a machine assembly of the tubes and baffles in a bundle assembly of a shell and tube type heat exchanger. The bundle comprises tubes inserted through baffles. The bundle is assembled using a holding fixture that includes anti-rotational features to secure baffles in a desired orientation. Following assembly, the bundle assembly is temporarily fixtured using pressure applying means such as plates and rods, and is then permanently affixed using an adhesive composition. After adhesive is applied, bundles, with the pressure applying means still attached, are preserved on racks and heat treated to cure and permanently set the adhesive.

  • Publication number: 20130292254
    Abstract: Disclosed herein are methods of cleaning a lipseal and/or cup bottom of an electroplating device by removing metal deposits accumulated in prior electroplating operations. The methods may include orienting a nozzle such that it is pointed substantially at the inner circular edge of the lipseal and/or cup bottom, and dispensing a stream of cleaning solution from the nozzle such that the stream contacts the inner circular edge of the lipseal and/or cup bottom while they are being rotated, removing metal deposits. In some embodiments, the stream has a velocity component against the rotational direction of the lipseal and/or cup bottom. In some embodiments, the deposits may include a tin/silver alloy. Also disclosed herein are cleaning apparatuses for mounting in electroplating devices and for removing electroplated metal deposits from their lipseals and/or cup bottoms. In some embodiments, the cleaning apparatuses may include a jet nozzle.
