Abstract:
A decrease of an etching rate of a substrate can be suppressed, and energy of ions irradiated to an inner wall of a chamber main body can be reduced. A plasma processing apparatus includes a DC power supply configured to generate a negative DC voltage to be applied to a lower electrode of a stage. In a plasma processing performed by using the plasma processing apparatus, a radio frequency power is supplied to generate plasma by exciting a gas within a chamber. Further, the negative DC voltage from the DC power supply is periodically applied to the lower electrode to attract ions in the plasma onto the substrate placed on the stage. A ratio occupied, within each of cycles, by a period during which the DC voltage is applied to the lower electrode is set to be equal to or less than 40%.

Claim (Index 5):
The plasma processing method of  claim 1 ,\n wherein the supplying of the radio frequency power is stopped in the period during which the negative DC voltage is applied, and the radio frequency power is supplied in a period during which the applying of the negative DC voltage is stopped.
