Abstract

Amorphous hydrogenated silicon carbide films were grown from capacitively coupled low frequency argon–tetramethylsilane plasmas. Mass spectrometry, optical emission spectroscopy and electrostatic probe were used to identify electron properties and chemical species under various deposition conditions. Film microstructure and mechanical properties were also characterized. The main goal of this analysis was to better understand the relationships between process parameters, gas-phase composition, film microstructure and tribological properties. A preliminary modeling of the plasma reactor was also carried out. First simulation results confirmed the trends from gas-phase analyses.
