    Abstract: Provided is a plasma processing method capable of obtaining sufficient repulsion force (adhesion) when processing plasma, and suppressing the generation of particles by reducing residual charges. In this method, plasma processing is performed on a subject in a state that the subject is adsorbed onto an electrostatic chuck on the top of a tray. The methods comprises: a plasma processing process of performing plasma processing in a state that heat conduction gas is supplied between a subject and the electrostatic chuck while adsorbing the subject by applying a first voltage to the electrostatic chuck as an application voltage; an application voltage reduction process of reducing the application voltage while exhausting the heat conduction gas remaining between the subject and the electrostatic chuck by stopping supplying the heat conduction gas at the termination of the plasma processing process; and a separation process of separating the subject from the electrostatic chuck by making the application voltage to the electrostatic chuck become zero after the application voltage reduction process. [Reference numerals] (AA) Voltage of an electrostatic chuck; (BB) Pressure of heat conduction gas; (CC) High frequency power for plasma; (DD,EE) First voltage; (FF) (opening and closing switch → close); (GG) Separate a wafer by a lifter pin; (HH) Plasma processing method of the present invention
