  • Publication number: 20130078376
    Abstract: Disclosed are methods of forming metal-nitride-containing films from the combination of amino-metal precursors and halogenated metal precursors, preferably forming SiN-containing films from the combination of aminosilane precursors and chlorosilane precursors. Varying the sequential reaction of the amino-metal precursors and halogenated metal precursors provide for the formation of metal-nitride-containing films having varying stoichiometry. In addition, the metal-nitride-containing film composition may be modified based upon the structure of aminometal precursor. The disclosed processes may be thermal processes or plasma processes at low temperatures.
