  • Patent number: 10450658
    Abstract: A process for surface activation or depassivation of an article, in particular an alloy, by immersion of the alloy in an aqueous acid solution. The surface activation methods of the present invention can be performed during a relatively short period of time and achieve reductions in production costs and provide environmental friendliness as compared to prior art processes. In a further embodiment, after surface activation, the article is immersed in a second liquid that prevents re-formation of a passivating oxide layer on the surface of the article. In a further embodiment the surface-activated alloys are subjected to surface engineering by a process that infuses carbon or nitrogen through the surface at a temperature sufficiently low to suppress precipitation of carbides or nitrides.

  • Publication number: 20120080318
    Abstract: A plurality of through holes in a workpiece are filled with a solid conductive material. The workpiece is immersed in an electroplating solution, with the through holes covered at one end by a portion of a conductive plating base. The electroplating solution is permitted to fill the through holes in the workpiece and contact the portion of the conductive plating base. A voltage applied to the conductive plating base enables an electroplating operation that deposits the solid conductive material on the portion of the conductive plating base to thereby fill the through holes with the solid conductive material.

  • Publication number: 20110284386
    Abstract: A method for electrofilling large, high aspect ratio recessed features with copper without depositing substantial amounts of copper in the field region is provided. The method allows completely filling recessed features having aspect ratios of at least about 5:1 such as at least about 10:1, and widths of at least about 1 ?m in a substantially void-free manner without depositing more than 5% of copper in the field region (relative to the thickness deposited in the recessed feature). The method involves contacting the substrate having one or more large, high aspect ratio recessed features (such as a TSVs) with an electrolyte comprising copper ions and an organic dual state inhibitor (DSI) configured for inhibiting copper deposition in the field region, and electrodepositing copper under potential-controlled conditions, where the potential is controlled not exceed the critical potential of the DSI.

  • Publication number: 20110076390
    Abstract: Methods are provided for multi-step Cu metal plating on a continuous Ru metal film in recessed features found in advanced integrated circuits. The use of a continuous Ru metal film prevents formation of undesirable micro-voids during Cu metal filling of high-aspect-ratio recessed features, such as trenches and vias, and enables formation of large Cu metal grains that include a continuous Cu metal layer plated onto the continuous Ru metal film. The large Cu grains lower the electrical resistivity of the Cu filled recessed features and increase the reliability of the integrated circuit.
