 Wise Probe Data

       •  Ar+CF4 Varying mix ratio @ 20mTorr


      •  Ar, O2, CF4 @ 10mTorr by Auto Linear Scanner


     •  Measurement with a coating probe
   *  In order to diagnose processing plasmas (etching or deposition), we need to coat an insulating layer
             on the probe tip as a protection layer.
   * Comparison with a probe with Al2O3 coated (~10um) and a metal probe.
             (Voltage reduction compensation due to the oxide layer impedance.)
