    摘要: A method is provided for forming a nitrided high-k film in an atomic layer deposition process (ALD) process. The method includes receiving a substrate in a process chamber, maintaining the substrate at a temperature sufficient for ALD of a nitrided high-k film, and depositing the nitrided high-k film on the substrate by exposing the substrate to a gas pulse sequence that includes, in any order: a) exposing the substrate to a gas pulse comprising a metal-containing precursor, b) exposing the substrate to a gas pulse comprising an oxygen-containing gas, and c) exposing the substrate to a gas pulse comprising trisilylamine gas, where the exposing the substrate to the trisilylamine gas yields the nitrided high-k film that includes nitrogen and that is substantially free of silicon, and repeating the gas pulse sequence. A trisilylamine gas exposure may also be used to nitride a deposited high-k film.

    摘要: A method of forming a material over a substrate includes performing at least one iteration of the following temporally separated ALD-type sequence. First, an outermost surface of a substrate is contacted with a first precursor to chemisorb a first species onto the outermost surface from the first precursor. Second, the outermost surface is contacted with a second precursor to chemisorb a second species different from the first species onto the outermost surface from the second precursor. The first and second precursors include ligands and different central atoms. At least one of the first and second precursors includes at least two different composition ligands. The two different composition ligands are polyatomic or a lone halogen. Third, the chemisorbed first species and the chemisorbed second species are contacted with a reactant which reacts with the first species and with the second species to form a reaction product new outermost surface of the substrate.
