  • Publication number: 20140174921
    Abstract: An apparatus for sputtering wherein magnets within the magnetron of a sputtering source are positioned such that Ar+ ions arriving at the surface of a multi-piece target do not strike the target perpendicular to the surface at the gaps between the sectors of the target. The off-angle bombardment of the Ar+ ions ensures that the Ar+ ions do not result in the sputtering and deposition of target backing material through the gap between the target sectors.

  • Publication number: 20140174914
    Abstract: Embodiments provided herein describe methods and systems for depositing material onto a surface. A target including a material in a porous state is provided. The density of the material in the porous state is less than 93% of the absolute density of the material. The target is positioned over a surface. At least some of the material is caused to be ejected from the target and deposited onto the surface. Films deposited from the porous targets exhibit significantly fewer particle defects than films of the same material deposited from the conventionally preferred higher-density targets. Brittle materials, such as alloys of refractory metals and silicon, seem to particularly benefit. The larger, less-uniform layered grains of the porous targets seem less prone to 10-micron-scale delamination than the smaller, more uniform grains of denser targets.

  • Publication number: 20140166616
    Abstract: Methods and apparatus for processing using a remote plasma source are disclosed. The apparatus includes an outer chamber, a remote plasma source, and a showerhead. Inert gas ports within the showerhead assembly can be used to alter the concentration and energy of reactive radical or reactive neutral species generated by the remote plasma source in different regions of the showerhead. This allows the showerhead to be used to apply a surface treatment to different regions of the surface of a substrate. Varying parameters such as the remote plasma parameters, the inert gas flows, pressure, and the like allow different regions of the substrate to be treated in a combinatorial manner.

  • Publication number: 20140144512
    Abstract: Provided are methods and systems for dispensing different chemicals used for high productivity combinatorial processing. A dispense panel may include multiple inlet lines for supplying different chemicals. Each inlet line is connected to its own three-way valve that either allows the supplied chemical to flow from the inlet line towards a dispense valve connected to a dispense manifold (during dispensing of the supplied chemical) or allows another chemical to flow from the dispense valve to a waste manifold (during priming of the dispense manifold with this other chemical). Specifically, during priming a chemical supplied from its inlet line and is passed through a corresponding three-way valve and is directed to its dispense valve and then into the dispense manifold. Other dispense valves and three-way valves of the dispense panel allow this chemical to flow out of the dispense manifold, thereby priming remaining parts of the panel.

  • Publication number: 20140017904
    Abstract: Methods of this invention relate to filling gaps on substrates with a solid dielectric material by forming a flowable film in the gap. The flowable film provides consistent, void-free gap fill. The film is then converted to a solid dielectric material. In this manner gaps on the substrate are filled with a solid dielectric material. According to various embodiments, the methods involve reacting a dielectric precursor with an oxidant to form the dielectric material. In certain embodiments, the dielectric precursor condenses and subsequently reacts with the oxidant to form dielectric material. In certain embodiments, vapor phase reactants react to form a condensed flowable film.
