    Abstract: An electrostatic chuck protection method includes providing an exposed chuck surface with a protective surface for preventing adherence of foreign materials including a substance exhibiting volatility in a vacuum environment, and removing the protective surface in order to perform a process of forming a substrate electrostatically held on the chuck surface with a surface layer including a substance having volatility in a vacuum chamber. The protective surface may be provided when a low vacuum pumping mode of operation is performed in a vacuum environment surrounding the chuck surface.
