  • Patent number: 8002894
    Abstract: In a processing apparatus including a diaphragm valve provided on a process gas discharge line for discharging a process gas from a processing chamber and configured to control the internal pressure of the processing chamber by adjusting the opening of the diaphragm valve, an antistatic agent source is connected to the process gas discharge line at a position upstream of the diaphragm valve. Damage of a diaphragm valve element due to spark discharge resulted from electric charge generated by friction between the gas flowing through the diaphragm valve and the diaphragm valve element can be prevented.
