The surface of the electrostatic chuck is etched with the reactive agent to remove debris. An apparatus for cleaning an electrostatic chuck is also provided, the apparatus comprising: a process chamber; an elongate arm having a reach disposed through a wall of the process chamber; an electrostatic chuck attached to the elongate arm; a cleaning station located within the reach of the elongate arm; and a reactive gas source that is operatively connected to the cleaning station.
