Abstract:
1. A cyclic deposition method of forming a phase-stabilized nitrogen-containing film comprising a solid solution having a stoichiometric ratio of Mm zx Ms (z-x) X, where Mm zx and Ms (z-x) are transition metals, one belonging to Group V, another belonging either to Group IV or to Group VI of Periodic Table, x varies in a range from greater than 0 to less than 1 and z varies in a range from greater than x to 1, wherein the phase-stabilized nitrogen-containing film comprises a matrix material and a phase stabilizer within the solid solution, wherein the phase-stabilized nitrogen-containing film is formed on a substrate within a reactor by exposing the substrate to a pulse of a matrix material precursor and a phase stabilizer precursor, removing an unreacted matrix material precursor and an unreacted phase stabilizer precursor from the reactor, exposing the substrate to a pulse of a nitrogen-containing reactant, and removing an unreacted nitrogen-containing reactant from the reactor, and wherein the phase stabilizer stabilizes the matrix material in a solution phase that is different from a native phase of the matrix material that would be formed under identical film formation conditions.
