Dosimetry using optical emission spectroscopy/residual gas analyzer in conjunction with ion current
摘要:
The present invention generally provides methods and apparatus for controlling ion dosage in real time during plasma processes. In one embodiment, ion dosages may be controlled using in-situ measurement of the plasma from a mass distribution sensor combined with in-situ measurement from an RF probe.
