Claim:
1. A method of manufacturing a semiconductor device, comprising: (a) forming a thin film containing a predetermined element, oxygen and carbon on a substrate by performing a cycle a predetermined number of times, the cycle including: (a-1) supplying to the substrate a source gas containing the predetermined element, carbon and a halogen element, the source gas having a chemical bond between the predetermined element and carbon; (a-2) supplying an oxidizing gas to the substrate; and (a-3) supplying a catalytic gas free of oxygen to the substrate; (b) removing a first impurity containing H (c) removing a second impurity different from the first impurity and containing a hydrocarbon compound from the thin film formed in (a) by thermally processing the thin film at a second temperature equal to or higher than the first temperature after performing (b).
