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.
