Claim Text:
1. A method for forming a silicon oxycarbonitride film, comprising: supplying a gas containing a silicon precursor having an oxygen-containing group onto a process surface of a workpiece such that silicon (Si) bonded with oxygen (O) is adsorbed or deposited on the process surface; supplying a gas containing a carbon precursor onto the process surface such that some of substituents bonded to Si are substituted with hydrocarbon groups (R); and supplying a nitriding gas onto the process surface subjected to the supplying a gas containing a silicon precursor and the supplying a gas containing a carbon precursor such that some of hydrocarbon groups (R) bonded to Si are substituted with amino groups (NH), wherein a silicon oxycarbonitride film is formed on the process surface by the supplying the gas containing the silicon precursor, the supplying gas containing the carbon precursor and the supplying a nitriding gas without performing an oxidation process.
