Abstract:
A method for controlling a plasma processing apparatus having a first electrode and a second electrode provided facing each other inside a processing chamber thereof that generates plasma inside said processing chamber by applying high frequency power for plasma generation having a first frequency to said first electrode via a first matching device and applying high frequency power for biasing having a second frequency lower than said first frequency to said second electrode via a second matching device to perform a specific type of plasma processing on a target object placed on said second electrode, comprising:a step in which high frequency power of steady-state power is applied to said first electrode and high frequency power at a level that enables, at least, matching of said high frequency power for biasing is applied to said second electrode; and a step in which said high frequency power applied to said second electrode is raised to a steady-state level after said high frequency power for biasing has been substantially matched.
