Abstract:
1. A method of manufacturing a semiconductor device, the method comprising forming a nitride film on a substrate by performing a cycle multiple times, the cycle including: (a) supplying a source gas to the substrate; (b) supplying a plasma-excited hydrogen-containing gas to the substrate; (c) supplying a plasma-excited or thermally excited nitriding gas to the substrate; and (d) supplying at least one of a plasma-excited nitrogen gas and a plasma-excited rare gas to the substrate, wherein the step (b) is performed in one of a time period after the step (a) and a time period after the step (c), and the step (d) is performed in one of the time period after the step (a) and the time period after the step (c) other than the time period where the step (b) is performed.
