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. The
method comprises patterning the electrodes, first insulating layer,
interconnect layer, and second insulating layer to form the ESC.
