Electrostatic chucking force measurement tool for process chamber carriers
Last updated:
Abstract:
An electrostatic chucking force tool is described that may be used on workpiece carriers for micromechanical and semiconductor processing. One example includes a workpiece fitting to hold a workpiece when gripped by an electrostatic chucking force by an electrostatic chuck, an arm coupled to the workpiece fitting to pull the workpiece through the workpiece fitting laterally across the chuck, and a force gauge coupled to the arm to measure an amount of force with which the workpiece fitting is pulled by the arm in order to move the workpiece.
