Abstract:
A method of etching a film of a workpiece, which includes: measuring a second flow rate of a first gas based on an increase rate of an internal pressure of a first chamber in a state in which a valve is closed and the first gas is supplied into the first chamber at a first flow rate adjusted by a flow rate controller, and calibrating the flow rate controller using the measured second flow rate; supplying a second gas into the first chamber; exhausting the first chamber; supplying a mixed gas of the first and second gases into the first chamber with the workpiece not mounted on a stage; forming a reaction product from the film by supplying the mixed gas into the first chamber with the workpiece mounted on the stage; and removing the reaction product by heating the workpiece with the workpiece accommodated in a second chamber.

Claim (Index 2):
The method of  claim 1 , wherein the film is a silicon oxide film, the first gas is an HF gas, and the second gas is an NH 3  gas.
