  • Publication number: 20060002052
    Abstract: The present invention is directed to a J-R electrostatic clamp (ESC) and method for forming same. The ESC comprises a ceramic layer for clamping a wafer thereto, and a plurality of electrodes arranged across the ceramic layer in an interior region and a peripheral region of the backside surface, wherein a plurality of electrode groups are defined by electrodes in the interior regions and peripheral regions. A first insulating layer generally isolates the electrode groups from one another, and an interconnect layer comprising a plurality of electrically conductive vias and interconnects electrically connect the electrodes associated with each respective electrode group. Each electrode group comprises a connection node, wherein the respective electrode group is operable to connect to a respective voltage potential. A second insulating layer generally encapsulates the interconnect layer.
