  • Publication number: 20200135430
    Abstract: A plasma processing apparatus comprises a processing chamber, a gas supply unit, a power supply unit and a frequency control unit. The processing chamber accommodates a target object. The gas supply unit supplies a processing gas into the processing chamber. The power supply unit supplies a power of a predetermined frequency band into the processing chamber to generate plasma of the processing gas in the processing chamber. The frequency control unit sweeps a frequency of the power supplied into the processing chamber by the power supply unit from a first frequency to a second frequency at the time of generating the plasma of the processing gas in the processing chamber.
