    Abstract: Methods for selectively depositing oxide thin films on a dielectric surface of a substrate relative to a metal surface are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a first precursor comprising oxygen and a species to be included in the oxide, such as a metal or silicon, and a second plasma reactant. In some embodiments the second plasma reactant comprises a plasma formed in a reactant gas that does not comprise oxygen. In some embodiments the second plasma reactant comprises plasma generated in a gas comprising hydrogen.

    Abstract: A method for depositing a ruthenium-containing film on a substrate by a cyclical deposition process is disclosed. The method may include: contacting the substrate with a first vapor phase reactant comprising a metalorganic precursor, the metalorganic precursor comprising a metal selected from the group consisting of a cobalt, nickel, tungsten, molybdenum, manganese, iron, and combinations thereof. The method may also include; contacting the substrate with a second vapor phase reactant comprising ruthenium tetroxide (RuO4); wherein the ruthenium-containing film comprises a ruthenium-metal alloy. Semiconductor device structures including ruthenium-metal alloys deposited by the methods of the disclosure are also disclosed.

    Abstract: A method for depositing a metal film onto a substrate is disclosed. In particular, the method comprises pulsing a metal halide precursor onto the substrate and pulsing a decaborane precursor onto the substrate. A reaction between the metal halide precursor and the decaborane precursor forms a metal film, specifically a metal boride.
