Claim:
1. A method of manufacturing a semiconductor device, comprising forming a thin film containing silicon, oxygen and carbon on a substrate by performing a cycle a predetermined number of times, the cycle comprising: supplying a precursor gas containing silicon, carbon and a halogen element and having an Si—C bonding, together with a first catalytic gas to the substrate, the first catalytic gas containing N having lone pair electrons; and supplying an oxidizing gas together with a second catalytic gas to the substrate, the second catalytic gas containing N having lone pair electrons, wherein a carbon concentration in the thin film is controlled by adjusting at least one of a supply amount of the second catalytic gas, a ratio of a flow rate of the second catalytic gas to a sum of flow rates of the oxidizing gas and the second catalytic gas, and a partial pressure of the second catalytic gas in the act of supplying the oxidizing gas together with the second catalytic gas.
