Abstract:
According to one embodiment, a plasma processing apparatus includes a processing chamber, a sample stage that is disposed inside the processing chamber and electrically divided into a plurality of regions on which a sample is placed, an electromagnetic wave introduction unit that introduces electromagnetic waves into the processing chamber, and a bias power applying unit that applies bias power to the sample stage, in which the bias power applying unit is configured to include a first radio frequency power applying unit that applies first radio frequency power to a first region out of the plurality of electrically divided regions of the sample stage, a second radio frequency power applying unit that applies second radio frequency power to a second region out of the plurality of electrically divided regions of the sample stage, and a phase adjuster that controls the first radio frequency power applying unit and the second radio frequency power applying unit to shift the phases of the first radio frequency power and the second radio frequency power by a predetermined amount.

Claim (Index 7):
The plasma processing method according to  claim 5 , further comprising:\n controlling the phase difference so that the phase difference becomes a phase difference corresponding to the predetermined value obtained based on a correlationship between the voltage difference and the phase difference.
