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 1):
A plasma processing method including cleaning of an inside of a chamber main body of a plasma processing apparatus,\n wherein the plasma processing apparatus comprises: the chamber main body which provides a chamber; a stage, provided within the chamber, having an electrostatic chuck configured to hold a processing target object placed thereon; and a temperature control device configured to adjust a temperature of the electrostatic chuck, and wherein the plasma processing method comprises: etching an etching target film of the processing target object placed on the electrostatic chuck by generating plasma of a processing gas containing a fluorocarbon gas and/or a hydrofluorocarbon gas within the chamber, the etching of the etching target film including a main etching of etching the etching target film in a state that the temperature of the electrostatic chuck is set to be equal to or lower than \u221230\u00b0 C. by the temperature control device; carrying-out the processing target object from the chamber after the etching of the etching target film is performed; and cleaning the inside of the chamber main body by generating plasma of a cleaning gas containing oxygen within the chamber in a state that the temperature of the electrostatic chuck is set to be equal to or higher than 0\u00b0 C. by the temperature control device after the carrying-out of the processing target object is performed.
