20090191424 | MANUFACTURING METHOD FOR A COMPOSITE METAL WIRE USED AS A PACKAGING WIRE AND PRODUCTS THEREOF - A manufacturing method for a composite metal wire used as semiconductor packaging wire and products thereof. Au, Ag and Cu materials are melted in a vacuum melting furnace, and then trace metal elements are added into the vacuum melting furnace and melted together with Au, Ag and Cu materials to obtain a composite material. The obtained composite material is drawn by a fist thick drawing machine, a second thick drawing machine and a first thin drawing machine to obtain a composite metal wire with a predetermined diameter. An Au layer is electroplated to the surface of the composite metal wire. The composite metal wire with Au layer is then drawn by a thin drawing machine, a very thin drawing machine and an ultra thin drawing machine to obtain an ultra thin composite metal wire with a predetermined diameter. Finally, the surface of the composite metal wire is washed and the composite metal wire is heat treated to ensure a final product with desirable physical properties, e.g. breaking load and elongation. | 07-30-2009 |

20120021248 | SYNTHESIS OF NANOPEAPODS BY GALVANIC DISPLACEMENT OF SEGMENTED NANOWIRES - A method for fabricating nanostructures, which includes the steps of forming a multi-segmented nanowire; and performing a galvanic displacement reaction on the multi-segmented nanowire. The method utilizes template directed electrodeposition to fabricate nanowires with alternating layers of sacrificial/noble metal, enabling a new level of control over particle spacing, aspect ratio, and composition. Moreover, by exploiting the redox potential dependent reaction of galvanic displacement, nanopeapod materials can be extended (semiconductor/metal, p-type/n-type, metal/metal, ferromagnetic/nonmagnetic, etc.) beyond the fundamental metal/metal-oxide nanopeapods synthesized by high temperature techniques. In accordance with an exemplary embodiment. Co/Au and Ni/Au multisegmented nanowires were used to create Te/Au nanopeapods by galvanic displacement, producing Te nanotubes and nanowires with embedded Au particles, respectively. | 01-26-2012 |
