    Abstract: The current disclosure relates to methods of depositing transition metal on a substrate. The disclosure further relates to a transition metal layer, to a structure and to a device comprising a transition metal layer. In the method, transition metal is deposited on a substrate by a cyclical deposition process, and the method comprises providing a substrate in a reaction chamber, providing a transition metal precursor to the reaction chamber in a vapor phase and providing a reactant to the reaction chamber in a vapor phase to form transition metal on the substrate. The transition metal precursor comprises a transition metal from any of groups 4 to 6, and the reactant comprises a group 14 element selected from Si, Ge or Sn.

    Abstract: Methods are provided for selectively depositing a material on a first metal or metallic surface of a substrate relative to a second, dielectric surface of the substrate, or for selectively depositing metal oxides on a first metal oxide surface of a substrate relative to a second silicon oxide surface. The selectively deposited material can be, for example, a metal, metal oxide, metal nitride, metal silicide, metal carbide and/or dielectric material. In some embodiments a substrate comprising a first metal or metallic surface and a second dielectric surface is alternately and sequentially contacted with a first vapor-phase metal halide reactant and a second reactant. In some embodiments a substrate comprising a first metal oxide surface and a second silicon oxide surface is alternately and sequentially contacted with a first vapor phase metal fluoride or chloride reactant and water.

    Abstract: Vapor deposition processes are provided in which a material is selectively deposited on a first surface of a substrate relative to a second organic surface. In some embodiments a substrate comprising a first surface, such as a metal, semi-metal or oxidized metal or semi-metal is contacted with a first vapor phase hydrophobic reactant and a second vapor phase reactant such that the material is deposited selectively on the first surface relative to the second organic surface. The second organic surface may comprise, for example, a self-assembled monolayer, a directed self-assembled layer, or a polymer, such as a polyimide, polyamide, polyurea or polystyrene. The material that is deposited may be, for example, a metal or metallic material. In some embodiments the material is a metal oxide, such as ZrO2 or HfO2. In some embodiments the vapor deposition process is a cyclic chemical vapor deposition (CVD) process or an atomic layer deposition (ALD) process. In some embodiments the material is deposited on the first surface relative to the second surface with a selectivity of greater than about 50%, greater than about 60%, greater than about 70%, greater than about 80%, greater than about 90% or greater than about 95%.
