System Protection of Equipment
  1. Protect over current, Built in protect over current of Vacuum pump, RF power supply and main unit
  2. Protect quartz oscillator, When matching unit have miss matching, Automatic RF power down and protect quartz oscillator
  3. Door panel inter lock, Built in inter lock switch
  4. External cover safety lock switch
  5. Emergency stop switch
System Protections by Software in PLC

  When occurred following conditions, Equipment stop and Error will display.

  1. In case of RF power is out of setting value.
  2. In case of gas flow (CF4, O2) is out of setting flow rate.
  3. In case of RFW power is over permission value.
  4. In case of Vacuum pressure does not reach within setting time.
  5. After finish plasma process, chamber does not become atmosphere.
