Abstract:
There is provided a method of forming a silicon oxide film on a target surface on which a silicon oxide film and a silicon nitride film are exposed. The method comprises placing a workpiece having the target surface on which the silicon oxide film and the silicon nitride film are exposed, in a processing container under a depressurized atmosphere; forming a spacer silicon nitride film to be a sacrificial film on the target surface on which the silicon oxide film and the silicon nitride film are exposed; and substituting the spacer silicon nitride film with a substitution silicon oxide film by supplying thermal energy, oxygen radicals and hydrogen radicals onto the workpiece.

Claim (Index 12):
The apparatus of  claim 11 , wherein, when the spacer silicon nitride film is substituted with the substitution silicon oxide film, the controller performs control to generate the oxygen radicals and the hydrogen radicals by supplying an oxygen gas and a hydrogen gas while heating the workpiece to a temperature in the range of 800 to 900 degrees C., and to substitute the spacer silicon nitride film with the substitution silicon oxide film by the oxygen radicals and the hydrogen radicals.
