    Abstract: PROBLEM TO BE SOLVED: To minimize degradation in performance of the electrostatic chuck of an impurity introduction layer formation device.SOLUTION: The electrostatic chuck protection method includes a step for providing a protective surface 23 that prevents adhesion of foreign matters containing a nonvolatile material in a vacuum environment on an exposed chuck surface 13, and a step for releasing the protective surface 23 in order to execute a process for forming a surface layer containing a material having volatility in the vacuum environment on a substrate W attracted electrically to the chuck surface 13. The protective surface 23 may be provided when performing low vacuum evacuation operation of the vacuum environment surrounding the chuck surface.
