Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: forming an oxide film having a predetermined thickness on a substrate by alternately repeating: (a) forming an element-containing layer on the substrate by supplying a source gas containing an element into a process vessel accommodating the substrate through a first nozzle; and (b) changing the element-containing layer to an oxide layer by: simultaneously supplying an oxygen-containing gas through a second nozzle different from the first nozzle and a hydrogen-containing gas through the first nozzle into the process vessel having an inside pressure lower than atmospheric pressure; mixing and reacting the oxygen-containing gas with the hydrogen-containing gas in a non-plasma atmosphere within the process vessel to generate an atomic oxygen; and oxidizing the element-containing layer by the atomic oxygen; wherein the steps (a) and (b) are performed while heating the substrate, an inside of the process vessel, an inside of the first nozzle and an inside of the second nozzle to a temperature equal to a film-forming temperature.
