Electrostatic chuck apparatus and method for efficiently dechucking a substrate therefrom

摘要

Within both a electrostatic chuck apparatus and a method for fabricating a substrate while employing a fabrication apparatus having assembled therein the electrostatic chuck apparatus there is employed: (1) an electrostatically energizable substrate plate sized to accommodate a substrate; and (2) an electrically conductive lift pin movably positionable with respect to the electrostatically energizable substrate plate such as to optionally contact and lift the substrate when positioned upon the electrostatically energizable substrate plate, further wherein the electrically conductive lift pin is connected to ground through a switch. Both the electrostatic chuck apparatus and the method provide for more efficient dechucking of the substrate positioned and electrostatically fixed upon the electrostatic chuck apparatus.
