- Process STBb is performed after process STBa.
- the control unit 2 controls each part of the plasma processing apparatus 1 to perform a second process in the chamber 10.
- the control unit 2 controls one or more actuators 54 to adjust the contact pressure of the top plate 51 against the heat transfer sheet 53 in order to set the temperature of the top plate 51 to a second target temperature.
