Research output: Contribution to journalArticle


Techniques available for real time, in situ monitoring of surface chemistry during plasma processing are reviewed. Emphasis is given to recent uses of attenuated-total-reflection Fourier transform infrared (ATR-FTIR) spectroscopy to study surface bond vibrations during plasma cleaning and passivation of Si and GaAs surfaces. Examples are chosen to demonstrate the utility of real-time monitoring of surfaces for developing and optimizing plasma processes used in manufacturing of electronic and optoelectronic devices.
