Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: loading a substrate into a process vessel; performing a process to form one of an oxide film, a nitride film and an oxynitride film on the substrate by alternately repeating: (a) forming a layer containing an element on the substrate by supplying a first source gas containing the element and a second source gas containing the element into the process vessel and exhausting the first source gas and the second source gas from the process vessel; (b) changing the layer containing the element into one of an oxide layer, a nitride layer, and an oxynitride layer by supplying a reaction gas different from the first source gas and the second source gas into the process vessel and exhausting the reaction gas from the process vessel; and unloading the processed substrate from the process vessel, wherein the first source gas is more reactive than the second source gas, and an amount of the first source gas supplied into the process vessel is set to be less than that of the second source gas supplied into the process vessel.
