Abstract:
A time period for cleaning performed to remove a deposit formed within a chamber main body can be reduced. A plasma processing method including the cleaning of an inside of the chamber main body of a plasma processing apparatus is provided. The method includes etching including a main etching of etching an etching target film of a processing target object placed on a stage in a low temperature by generating plasma of a processing gas containing a fluorocarbon gas and/or a hydrofluorocarbon gas; carrying-out the processing target object from a chamber; and cleaning the inside of the chamber main body by generating plasma of a cleaning gas in a state that a temperature of an electrostatic chuck is set to be high.

Claim (Index 5):
The plasma processing method of  claim 1 , further comprising:\n neutralizing the electrostatic chuck after the etching of the etching target film is performed and before the carrying-out of the processing target object from the chamber is performed; and raising the temperature of the electrostatic chuck by the temperature control device when the neutralizing of the electrostatic chuck is being performed, in order to raise the temperature of the electrostatic chuck to be equal to or higher than 0\u00b0 C. before the cleaning of the inside of the chamber main body is performed.
