Abstract: Disclosed are methods for forming a silicon-containing layer on a substrate, the method comprising the steps of introducing into a reactor containing a substrate a vapor including an Si-containing film forming composition having a cyclic organoaminosilane precursor having the formula: wherein R is NH2; R? is H or NH2; x, y or z=2 to 5; provided that x?4 in the formula (III), and depositing at least part of the cyclic organoaminosilane precursor onto the substrate to form the silicon-containing layer on the substrate using a vapor deposition process. The cyclic organoaminosilane precursors include bis(pyrrolidino)silacyclopentane and 1-(pyrrolidino)silacyclopentane.

Abstract: Provided are: forming a thin film made of a specific element alone on a substrate by performing a specific number of times a cycle of: supplying a first source to the substrate, the first source containing the specific element and a halogen-group; and supplying a second source to the substrate, the second source containing the specific element and an amino-group, and having amino-group-containing ligands whose number is two or less in its composition formula and not more than the number of halogen-group-containing ligands in the composition formula of the first source.

Abstract: There is provided a method of manufacturing a semiconductor device, including: forming a film containing a specific element, nitrogen, and carbon on a substrate, by alternately performing the following steps a specific number of times: a step of supplying a source gas containing the specific element and a halogen element, to the substrate; and a step of supplying a reactive gas composed of three elements of carbon, nitrogen, and hydrogen and having more number of a carbon atom than the number of a nitrogen atom in a composition formula thereof, to the substrate.

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.
