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 1):
A wafer unloading method for unloading a wafer from an electrostatic chuck table electrostatically holding said wafer by applying a voltage to said electrostatic chuck table, said wafer unloading method comprising:\n a voltage application stopping step of stopping the application of the voltage to said electrostatic chuck table electrostatically holding said wafer; a static eliminating voltage applying step of passing a current reverse in direction to a current passed to said electrostatic chuck table for electrostatically holding said wafer after performing said voltage application stopping step, thereby applying a static eliminating voltage for canceling peeling electrification to said electrostatic chuck table; and an unholding step of unholding said wafer from said electrostatic chuck table in the condition where said static eliminating voltage is being kept applied to said electrostatic chuck table, after performing said static eliminating voltage applying step.
