The present work shows the investigations of a-SiC(N,O):H thin films p
roduced by d.c. plasma-enhanced chemical vapor deposition under high p
ower conditions. In contrast to the traditional process we use liquid
precursors (hexamethyldisiloxane, hexamethyldisilazane) diluted in arg
on or nitrogen for decomposition in the glow discharge. Films were ana
lysed by different methods with regards to their composition and struc
ture (electron probe microanalysis, X-ray photoelectron spectroscopy,
glow discharge optical emission spectroscopy, infrared spectroscopy).
