摘要:
In accordance with an embodiment of the invention, there is provided an electrostatic chuck. The electrostatic chuck comprises an electrode, and a surface layer activated by a voltage in the electrode to form an electric charge to electrostatically clamp a substrate to the electrostatic chuck, the surface layer including a charge control layer comprising a surface resistivity of greater than about 1011 ohms per square.
