  • Publication number: 20190318912
    Abstract: A plasma processing apparatus includes a radio-frequency power supply that outputs modulated radio-frequency power which is generated such that a power level during a first period is higher than a power level during a second period that alternates with the first period. The plasma processing apparatus also includes a matching device that sets a load side impedance of the radio-frequency power supply during a monitoring period within the first period to an impedance that differs from an output impedance of the radio-frequency power supply. The monitoring period starts after a predetermined time length elapses from a start point of the first period. The radio-frequency power supply adjusts the power level of the modulated radio-frequency power such that a load power level, which is a difference between a power level of a traveling wave and a power level of a reflected wave, becomes a designated power level.
