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 3):
The wafer unloading method according to  claim 2 , further comprising:\n a suction pad contact making step of making the contact of a conductive suction pad with said wafer held on said electrostatic chuck table before performing said static eliminating voltage applying step; and a suction holding step of holding said wafer under suction by using said conductive suction pad, after performing said suction pad contact making step and before performing said air blow step.
