    摘要: Methods, systems, and apparatus for conducting chucking operations are disclosed that use an adjusted chucking voltage if a process shift occurs. In one implementation, a method includes conducting a first processing operation on a substrate in a processing chamber. The first processing operation includes applying a chucking voltage to an electrostatic chuck (ESC) in the processing chamber while the substrate is supported on the ESC. The method includes determining that a process shift has occurred. The determining that the process shift has occurred includes one or more of: determining that a center of the substrate has moved by a post-processing shift relative to a pre-processing location of the center prior to the first processing operation, or determining that a defect count of a backside surface of the substrate exceeds a defect threshold. The method includes determining an adjusted chucking voltage based on the occurrence of the process shift.

    摘要: A body of an electrostatic chuck comprises mesas disposed on a polished surface of the body. Each of the mesas comprises an adhesion layer disposed on the polished surface of the body, a transition layer disposed over the adhesion layer, and a coating layer disposed over the transition layer. The coating layer has a hardness of at least 14 GPa. The body further comprises a sidewall coating disposed over a sidewall of the body. A method for preparing the body comprises polishing the surface of the body and cleaning the polished surface. The method further comprises depositing the mesas by depositing the adhesion layer on the body, the transition layer over the adhesion layer, and the coating layer over the transition layer. Further, the method includes, polishing the mesas.
