Abstract

Hydrogen elimination reactions, abstraction and etching, are monitored in real-time using a differentially pumped mass spectrometer, while intermittently exposing a hydrogenated silicon surface to atomic deuterium. The mass spectrometer signals are used to predict the kinetics of the abstraction reaction, and to qualitatively treat the etch reaction.
