Abstract:
1. A thermal CVD method of forming an insulating film, consisting essentially of a film selected from the group consisting of a silicon oxide film, silicon nitride film, and silicon oxynitride film, the method comprising: supplying first, second, and third gases into a process chamber that accommodates a target substrate, while heating an interior of the process chamber at a process temperature and exhausting the interior of the process chamber, thereby forming the insulating film on the target substrate by deposition, wherein the first gas consists essentially of a silane family gas selected from the group consisting of hexachlorodisilane, hexaethylaminodisilane, bistertialbutylaminosilane, and dichlorosilane, the second gas consists essentially of a gas selected from the group consisting of an oxidizing gas, nitriding gas, and oxynitriding gas, the third gas consists essentially of ethylene, and is supplied into the process chamber without pre-heating, and the process temperature is set to fall within a range of from 450 to 600° C.
