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 11):
An apparatus for forming a silicon oxide film on a target surface on which a silicon oxide film and a silicon nitride film are exposed, comprising:\n a processing container in which a workpiece having the target surface on which the silicon oxide film and the silicon nitride film are exposed is accommodated; a gas supply part configured to supply a predetermined gas into the processing container; a heating mechanism configured to heat an interior of the processing container; an exhaust mechanism configured to exhaust the interior of the processing container to bring the processing container into a depressurized state; and a controller configured to control the gas supply part, the heating mechanism and the exhaust mechanism, wherein the controller controls the gas supply part, the heating mechanism and the exhaust mechanism to perform a process including: keeping the interior of the processing container under a predetermined depressurized atmosphere in a state where the workpiece is placed in the processing container; 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 by supplying a silicon precursor gas and a nitriding gas; 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.
