Abstract:
In a plasma processing apparatus, a controller controls one or both of a first high frequency power supply and a second high frequency power supply to periodically stop the supply of one or both of the first high frequency power and the second high frequency power. The controller also controls a switching unit to apply a DC voltage to a focus ring from a first time after a predetermined period of time in which a self-bias voltage of a lower electrode is decreased from a start point of each period in which one or both of the first high frequency power and the second high frequency power are supplied and to stop the application of the DC voltage to the focus ring during each period in which the supply of one or both of the first high frequency power and the second high frequency power is stopped.

Claim (Index 6):
A plasma processing method performed by using the plasma processing apparatus described in  claim 1  in a state where a substrate is mounted on the electrostatic chuck and a processing gas is supplied into the chamber, the method comprising:\n supplying one or both of the first high frequency power and the second high frequency power; and \n stopping the supply of one or both of the first high frequency power and the second high frequency power, \n wherein said supplying one or both of the first high frequency power and the second high frequency power and said stopping the supply of one or both of the first high frequency power and the second high frequency power are alternately executed, \n the method further comprising: \n applying the DC voltage to the focus ring from a first time after a predetermined period of time in which a self-bias voltage of the lower electrode is decreased from a start point of each period in which one or both of the first high frequency power and the second high frequency power are supplied; and \n stopping the application of the DC voltage to the focus ring during each period in which the supply of one or both of the first high frequency power and the second high frequency power is stopped.
