Abstract:
1. A processing apparatus comprising: a process chamber in which a process object is processed with a process gas; a plurality of gas flow lines each provided to flow a process gas there through, the gas flow lines including a process gas supply line for supplying the process gas from a process gas source into the process chamber and a process gas discharge line for discharging the process gas from the process chamber; a diaphragm valve provided on one of the gas flow lines; and an antistatic agent source connected to said one gas flow line at a position upstream, with respect to a flowing direction of the process gas flowing through said one gas flow line, of the diaphragm valve to supply an antistatic agent to said one gas flow line thereby to supply the antistatic agent to the diaphragm valve and to prevent the diaphragm valve from being electrically charged, and wherein the diaphragm valve is provided on the process gas discharge line as said one gas flow line, and wherein the antistatic agent source is connected to the gas discharge line at a position between the process chamber and the diaphragm valve so that the antistatic agent source is injected.
