    • A substrate processing apparatus includes an electrostatic chuck enclosing an electrostatic electrode plate and a chamber having a ground potential and housing the electrostatic chuck. When the absolute value of the potential generated at a wafer after DC discharge is generated between the wafer and the chamber is 0.5 kV, the potential of the electrostatic electrode plate is changed from 2.5 kV to 1.5 kV to generate DC discharge so that the absolute value of the potential of a placing surface of the wafer of the electrostatic chuck becomes 0.5 kV after the plasma etching process, the polarities of the potential of the placing surface after the change and the wafer become the same, and the absolute value of the potential difference between the wafer and the chamber becomes 0.5 kV or more. The wafer is then removed from the electrostatic chuck.

    • A substrate processing apparatus includes an electrostatic chuck enclosing an electrostatic electrode plate and a chamber having a ground potential and housing the electrostatic chuck. DC discharge is generated between a wafer and the chamber by setting the potential of the electrostatic electrode plate of the electrostatic chuck which is maintained at a first predetermined potential during a plasma etching process to a ground potential after the plasma etching process to increase the absolute value of the potential difference between the wafer and the chamber. DC discharge is then re-generated by applying, to the electrostatic electrode plate, DC voltage having the same potential as a second predetermined potential which is generated at the wafer after the DC discharge is generated, and by increasing the absolute value of the potential difference between the wafer and the chamber. The wafer is then easily removed from the electrostatic chuck.
