    Abstract: A method of forming a metal silicide can include depositing an interface layer on exposed silicon regions of a substrate, where the interface layer includes a silicide forming metal and a non-silicide forming element. The method can include depositing a metal oxide layer over the interface layer, where the metal oxide layer includes a second silicide forming metal. The substrate can be subsequently heated to form the metal silicide beneath the interface layer, using silicon from the exposed silicon regions, the first silicide forming metal of the interface layer and the second silicide forming metal of the metal oxide layer.

    Abstract: In some aspects, methods of forming a metal chalcogenide thin film are provided. According to some methods, a metal chalcogenide thin film is deposited on a substrate in a reaction space in a cyclical deposition process where at least one cycle includes alternately and sequentially contacting the substrate with a first vapor-phase metal reactant and a second vapor-phase chalcogen reactant. In some aspects, methods of forming three-dimensional structure on a substrate surface are provided. In some embodiments, the method includes forming a metal chalcogenide dielectric layer between a substrate and a conductive layer. In some embodiments the method includes forming an MIS-type contact structure including a metal chalcogenide dielectric layer.
