Latest Patents

David B. Smith holds a patent for an electrostatic chuck ground punch. This invention provides a method for clamping a workpiece using an electrostatic chuck (ESC). The ESC features a clamping plate with a clamping surface and one or more electrodes. By applying an electric potential to these electrodes, the workpiece can be selectively clamped to the clamping surface. The design includes a punch that is operably coupled to the clamping plate and an electrical ground. The punch comprises a trigger mechanism and a punch tip that translates between extended and retracted positions. When in the extended position, the punch tip is proud of the clamping surface, allowing it to effectively engage with the workpiece. Upon clamping, the punch tip translates toward the clamping surface, and the trigger mechanism imparts an impact force to create an electrical ground connection to the workpiece.
