Abstract:
A deposit on a target object can be removed or the amount thereof can be reduced after plasma etching is completed and before the target object is carried out of a chamber. A method of processing the target object is provided. The method includes etching including a main etching of etching an etching target film of the target object placed on a stage at a low temperature by generating plasma of a processing gas containing a fluorocarbon gas and/or a hydrofluorocarbon gas; raising, immediately after the etching is performed or immediately after the main etching is performed, a temperature of an electrostatic chuck; and carrying-out the target object from the chamber in a state that the temperature of the electrostatic chuck is set to a high temperature.

Claim (Index 1):
A method of processing a target object by using a plasma processing apparatus,\n wherein the plasma processing apparatus comprises: a chamber main body which provides a chamber; a stage, provided within the chamber, having an electrostatic chuck configured to hold the target object placed thereon; and a temperature control device configured to adjust a temperature of the electrostatic chuck, and wherein the method comprises: etching an etching target film of the 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; raising, immediately after the etching of the etching target film is performed or immediately after the main etching is performed, the temperature of the electrostatic chuck to be equal to or higher than 0\u00b0 C. by the temperature control device in a state that the target object is placed on the electrostatic chuck; and carrying-out the target object placed on the electrostatic chuck from the chamber in a state that the temperature of the electrostatic chuck is set to be equal to or higher than 0\u00b0 C. as a result of performing the raising of the temperature of the electrostatic chuck.
