Claim Text:
1. A method of forming a carbon-containing silicon film, comprising: adsorbing a silicon source on a workpiece by supplying a silicon source gas containing at least one chlorine group into a reaction chamber accommodating the workpiece and activating the supplied silicon source gas to react the activated silicon source gas with the workpiece; removing chlorine from the adsorbed silicon source containing chlorine by supplying an alkyl metal gas into the reaction chamber and activating the alkyl metal gas to react the activated alkyl metal gas with the adsorbed silicon source; and incorporating oxygen into the adsorbed silicon source by supplying oxygen into the reaction chamber and activating the supplied oxygen to react the activated oxygen with the adsorbed silicon source after removing chlorine, wherein adsorbing a silicon source, removing chlorine, and incorporating oxygen are sequentially repeated plural times.
