  • Patent number: 11488808
    Abstract: In a plasma processing apparatus, a mounting table includes a heater for adjusting a temperature of a mounting surface mounting thereon a consumable part consumed by plasma processing. A heater control unit controls a supply power to the heater such that the heater reaches a setting temperature. A measurement unit measures, while controlling the supply power to the heater such that the temperature of the heater becomes constant, the supply powers in a non-ignition state where plasma is not ignited and in a transient state where the supply power is decreased after the plasma is ignited. A parameter calculation unit calculates a thickness of the consumable part by performing fitting with a calculation model, which has the thickness of the consumable part as a parameter and calculates the supply power in the transient state, by using the measured supply powers in the non-ignition state and in the transient state.
