  • Patent number: 8338280
    Abstract: Embodiments relate to a method for fabricating nano-wires in nano-devices, and more particularly to nano-device fabrication using end-of-range (EOR) defects. In one embodiment, a substrate with a surface crystalline layer over the substrate is provided and EOR defects are created in the surface crystalline layer. One or more fins with EOR defects embedded within is formed and oxidized to form one or more fully oxidized nano-wires with nano-crystals within the core of the nano-wire.

  • Patent number: 8268733
    Abstract: A method of forming a device is presented. The method includes providing a wafer having an active surface and dividing the wafer into a plurality of portions. The wafer is selectively processed by localized heating of a first of the plurality of portions. The wafer is then repeatedly selectively processed by localized heating of a next of the plurality of portions until all plurality of portions have been selectively processed.

  • Patent number: 8101487
    Abstract: A method for fabricating a semiconductor device is presented. The method includes providing a substrate and forming a gate stack over the substrate. A first laser processing to form vacancy rich regions within the substrate on opposing sides of the gate stack is performed. The vacancy rich regions have a first depth from a surface of the substrate. A first implant causing end of range defect regions to be formed on opposing sides of the gate stack at a second depth from the surface of the substrate is also carried out, wherein the first depth is proximate to the second depth.

  • Publication number: 20110048957
    Abstract: A structure and method for forming a relatively thin diffusion barrier/seed bilayer for copper metallization in an electronic device is disclosed. A single layer of an alloy is formed over a dielectric (and possibly the copper layer). The alloy includes a copper platable metal (e.g., ruthenium) and a nitride forming material (e.g., tungsten) and nitrogen. The alloy layer is annealed, and the alloy naturally segregates into two layers. The first layer is a barrier layer including the nitride forming material and nitrogen. The second layer is a seed layer including the copper platable metal.
