Silicon carbide (Si1-xCx) and silicon carbonitride (SICxNy) films were
obtained by the low pressure chemical vapour deposition (LPCVD) metho
d at moderate (750-900 degrees C) and high (T > 900 degrees C) tempera
tures using liquid single organosilicon precursors such as hexamethyld
isilane (hmds) and hexamethyldisilazane (HMDS). Structural and composi
tional investigations of these films have been effected using various
analytical techniques: Rutheford backscattering spectrometry (RBS), X-
ray photoelectron spectroscopy (XPS), secondary ion mass spectrometry
(SIMS), Fourier transform infrared spectroscopy (FTIR), etc.
