  • Publication number: 20130081938
    Abstract: A magnetron sputtering apparatus in which a target is disposed to face a substrate includes a magnet array body including a magnet group arranged on a base body, and a rotating mechanism for rotating the magnet array body around an axis perpendicular to the substrate. In the magnet array body, N poles and S poles constituting the magnet group are arranged to be spaced from each other along a surface facing the target such that a plasma is generated based on a drift of electrons by a cusp magnetic field. Magnets located on the outermost periphery of the magnet group are arranged in a line to prevent the electrons from being released from constraint of the cusp magnetic field and jumping out of the cusp magnetic field. A distance between the target and the substrate during sputtering is equal to or less than 30 mm.

  • Patent number: 8076241
    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.
