| Zusammenfassung: | A temperature control method includes cooling an upper electrode and increasing a temperature of the upper electrode. A path having an inlet and an outlet is formed within the upper electrode. The upper electrode constitutes an evaporator. A compressor, a condenser and an expansion valve are connected in sequence between the outlet and the inlet of the path. A flow dividing valve is connected between an output of the compressor and the inlet to bypass the condenser and the expansion valve. In the cooling of the upper electrode, a coolant is supplied into the path via the compressor, the condenser and the expansion valve. In the increasing of the temperature of the upper electrode, the flow dividing valve is opened and the upper electrode is heated. |
