Abstract:
A plasma processing apparatus includes a chamber, a first electrode disposed in the chamber configured to receive a substrate loaded on the first electrode. A second electrode disposed in the chamber is opposed to the first electrode, and an RF power source is configured to switch between an on-state and an off-state. The RF power source supplies a source RF power to the first or the second electrode and supplies a bias RF power to the first electrode in the on-state. A first DC voltage supply alternately supplies a first DC voltage of negative polarity and a second DC voltage of negative polarity to the second electrode depending status of the first RF power source. The second DC voltage supply is turned on between first and second cycles where the first DC voltage is output to supply a third DC voltage of positive polarity to the first electrode.

Claim (Index 10):
A plasma processing apparatus comprising:\n a chamber; a first electrode disposed in the chamber, the first electrode configured to receive a substrate loaded onto the first electrode; a second electrode disposed in the chamber to oppose to the first electrode; a RF power source configured to be turned on from a first time to a second time to supply a source RF power to the first electrode or the second electrode and to supply a bias RF power to the first electrode, and to be turned off from the second time to a third time; a first DC voltage supply configured to supply a first DC voltage of negative polarity to the second electrode from the first time to the second time and to supply a second DC voltage of negative polarity to the second electrode from the second time to the third time, wherein an absolute value of the second DC voltage is greater than an absolute value of the first DC voltage; and a second DC voltage supply, wherein the second DC voltage supply is turned on between the second time and the third time to supply a third DC voltage of positive polarity to the first electrode.
