Abstract: A plasma processing apparatus for processing a surface of a to-be-processed substrate includes a processing chamber, a first electrode provided in the processing chamber, a second electrode arranged in opposition to the first electrode, a main power source for supplying the first or second electrode with power for generating a plasma, a biasing power source for supplying the second or first electrode with biasing power, a gas supplying unit for supplying a processing gas into the processing chamber and a control unit for controlling the main power source, the biasing power source and the gas supplying unit. The control unit performs a control such that, during a time of transition from a stationary state of plasma, in which a plasma processing is to be carried out, to a plasma quenching, an output of the main power source is kept not larger than an output of the biasing power source.
