Claim:
1. A method of manufacturing a semiconductor device, comprising: providing a substrate having an oxide film formed on a surface of the substrate; performing, a predetermined number of times, a cycle of non-simultaneously performing a process of supplying a precursor gas to the substrate, a process of supplying a carbon-containing gas to the substrate, and a process of supplying a nitrogen-containing gas to the substrate, or performing, a predetermined number of times, a cycle of non-simultaneously performing a process of supplying a precursor gas to the substrate and a process of supplying a gas containing carbon and nitrogen to the substrate, or performing, a predetermined number of times, a cycle of non-simultaneously performing a process of supplying a precursor gas containing carbon to the substrate and a process of supplying a nitrogen-containing gas to the substrate, the oxide film being used as an oxygen source to form a nitride layer containing oxygen and carbon as a seed layer on the oxide film; and forming a nitride film containing no oxygen and carbon as a first film on the seed layer.
