Abstract

We report on in situ detection of diatomic products of plasma sputtering and reactive ion etching using the technique of laser-induced fluorescence. The diatomic molecules SiN, SiO, and SiF are observed in the gas phase when a silicon surface is subjected to ion bombardment in plasmas containing N 2, O2, and CF4, respectively. Information about the production mechanisms is obtained from the measured product concentrations under varying plasma conditions.
