Abstract:
1. A parallel flat-panel type plasma processing apparatus comprising: a processing chamber provided with a first electrode and a second electrode where a placing table serves as the first electrode configured to place a substrate, and a high-frequency power is applied between the first and second electrodes to convert a processing gas into plasma thereby performing a plasma processing for the substrate; a temperature adjusting mechanism configured to adjust a temperature of the second electrode; a temperature setting unit configured to set the temperature of the second electrode in the plasma processing; a set temperature compensating unit configured to compensate the set temperature of the second electrode to become lower than the set temperature of the second electrode according to a used time elapsed after starting using a new second electrode; and a temperature controlling unit programmed to output a control signal for controlling the temperature adjusting mechanism based on the set temperature of the second electrode set by the temperature setting unit and the compensated temperature of the second electrode compensated by the set temperature compensating unit.
