摘要： An electrostatic clamp (ESC), system, and method for clamping a workpiece is provided. A clamping plate of the ESC has central disk and an annulus encircling the central disk, wherein the central disk is recessed from the annulus by a gap distance, therein defining a volume. Backside gas delivery apertures are positioned proximate to an interface between the annulus and the central disk. A first voltage to a first electrode of the annulus clamps a peripheral region of the workpiece to a first layer. A second voltage to a second electrode of the central disk generally compensates for a pressure of a backside gas within the volume. The ESC can be formed of J-R- or Coulombic-type materials. A cooling plate associated with the clamping plate further provides cooling by one or more cooling channels configured to route a cooling fluid therethrough.

摘要： An electrostatic chuck and method for clamping a workpiece is provided. The ESC comprises a clamping plate having a clamping surface, and one or more electrodes. An electric potential applied to the one or more electrodes selectively clamps the workpiece to the clamping surface. A punch is operably coupled to the clamping plate and an electrical ground, wherein the punch comprises a trigger mechanism and a punch tip. The punch tip translates between extended and retracted positions, wherein a point of the punch tip is proud of the clamping surface when the punch tip is in the extended position. The punch tip is configured to translate toward the clamping surface upon clamping the workpiece to the clamping plate. Upon reaching the retracted position, the trigger mechanism imparts an impact force to the punch tip, forcing the punch tip into the workpiece and providing an electrical ground connection to the workpiece.

摘要： One embodiment of the present invention relates to a method for declamping a semiconductor wafer that is electrically adhered to a surface of an electrostatic chuck by a clamping voltage. In this method, the clamping voltage is deactivated. For a time following the deactivation, a first region of the wafer is lifted an first distance from the surface of the electrostatic chuck while a second region of the wafer remains adhered to the surface of the electrostatic chuck. A predetermined condition is monitored during the time. The second region is lifted from the surface of the electrostatic chuck when the predetermined condition is met.

摘要： The present invention is directed to an apparatus and method of forming a thermos layer surrounding a chuck for holding a wafer during ion implantation. The thermos layer is located below a clamping surface, and comprises a vacuum gap and an outer casing encapsulating the vacuum gap. The thermos layer provides a barrier blocking condensation to the outside of the chuck within a process chamber by substantially preventing heat transfer between the chuck when it is cooled and the warmer environment within the process chamber.
