Abstract

Ellipsometry is shown to provide a sensitive evaluation of the surface cleaning process based on in-situ and ex-situ studies of the cleaning of Si, Ge, and InP surfaces. Both single wavelength and spectroscopic ellipsometry are shown to be applicable. The essentials of the measurement and sample results are discussed.
