Noninvasive monitoring of ion current and ion energy during plasma processing

Abstract
A technique has been developed for noninvasive monitoring of ion energy and ion current in plasma reactors. The technique relies on measurements of the applied rf bias current and voltage, which are interpreted using a fundamental, physical model of the plasma and its sheaths. By fitting the model to measured electrical waveforms, the technique determines the total ion current, the plasma potential and sheath voltage waveforms, and the ion energy distributions.Proceedings Title
