The infrared characterization of SiOxCy thin films deposited by means
of plasma-assisted chemical vapour deposition (PACVD) using the organo
metallic precursor, tetraethoxy orthosilicate (TEOS), is reported. It
is shown to be possible to determine the influence of a number of expe
rimental parameters on the stoichiometry and morphology of the films b
y means of reflection-absorption infrared spectroscopy (RAIRS).
