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 5):
The method of  claim 1 , wherein the gas supply part is further configured to supply an inert gas into the first chamber,\n wherein the supplying the second gas into the first chamber further includes supplying the inert gas into the first chamber.
