Abstract:
Disclosed herein is a wafer unloading method for unloading a wafer from an electrostatic chuck table electrostatically holding the wafer by applying a voltage to the electrostatic chuck table. The wafer unloading method includes a voltage application stopping step of stopping the application of the voltage to the electrostatic chuck table electrostatically holding the wafer, a static eliminating voltage applying step of passing a current reverse in direction to a current passed to the electrostatic chuck table for electrostatically holding the wafer after performing the voltage application stopping step, thereby applying a static eliminating voltage for canceling peeling electrification to the electrostatic chuck table, and an unholding step of unholding the wafer from the electrostatic chuck table in the condition where the static eliminating voltage is kept applied to the electrostatic chuck table, after performing the static eliminating voltage applying step.

Claim (Index 2):
The wafer unloading method according to  claim 1 , wherein said electrostatic chuck table has a holding surface for holding said wafer, an air discharge port opening to said holding surface, and an air passage having one end connected to said air discharge port and the other end connected to an air source;\n said wafer unloading method further comprising an air blow step of discharging air from said air discharge port after performing said static eliminating voltage applying step and before performing said unholding step; whereby the air is supplied from said air source through said air passage to said air discharge port and then discharged from said air discharge port toward said wafer held on said holding surface of said electrostatic chuck table.
