Abstract

Embodiments described herein generally relate to an electrostatic chuck (ESC). The ESC may contain a first plurality of electrodes adapted to electrostatically couple a substrate to the ESC and a second plurality of electrodes adapted to electrostatically couple the ESC to a substrate support. Instead of being integrally disposed within the substrate support, the ESC may be easily removed from the substrate support and removed from a chamber for maintenance or replacement purposes.
