    摘要: An apparatus and method for forming catalyst particles to grow nanotubes is disclosed. In addition, an apparatus and method for forming nanotubes using the catalytic particles is also disclosed. The particles formed may have different diameters depending upon how they are formed. Once formed, the particles are deposited on a substrate. Once deposited, the mobility of the particles is restricted and nanotubes and/or nanotube portions are grown on the particles. Nanotube portions having different diameters may be formed and the portions may be connected to form nanotubes with different diameters along the length of the nanotube.

    摘要: A method of forming a copper interconnect on a substrate comprises providing a substrate that includes a dielectric layer and a trench etched into the dielectric layer, depositing a barrier layer within the trench, using a palladium immobilization process to form a metal catalyst layer on the barrier layer, activating the metal catalyst layer, and using a vapor deposition process to deposit a copper seed layer onto the metal catalyst layer. The vapor deposition process may include PVD, CVD, or ALD. An electroplating process or an electroless plating process may then be used to deposit a bulk copper layer onto the copper seed layer to fill the trench. A planarization process may follow to form the final interconnect structure.

    摘要: A method and apparatus for a semiconductor device having a semiconductor device having increased conductive material reliability is described. That method and apparatus comprises forming a conductive path on a substrate. The conductive path made of a first material. A second material is then deposited on the conductive path. Once the second material is deposited on the conductive path, the diffusion of the second material into the conductive path is facilitated. The second material has a predetermined solubility to substantially diffuse to grain boundaries within the first material.
