METHOD FOR OPTIMIZED REMOVAL OF WAFER FROM ELECTROSTATIC CHUCK |
| 摘要 |
Systems and methods for optimally dechucking a wafer from an electrostatic chuck are described. The force on a lift-pin mechanism is monitored and a dechuck voltage is determined based on the force. The wafer is dechucked at the determined dechuck voltage.
