Abstract

Amorphous SiCN coatings are becoming increasingly attractive because of their mechanical, optical and electronic properties. In the present work, SiCN films were fabricated by PECVD from SiH₄/CH₄/N ₂/Ar gas mixtures at a temperature of 400°C. Mechanical characteristics such as hardness, Young's modulus, friction coefficient and stress were evaluated, respectively, by depth-sensing indentation, pin-on-disk, and curvature methods. Films deposited under optimized conditions exhibited a hardness of > 30 GPa, Young's modulus of > 190 GPa, elastic rebound of 85 %, and a compressive stress of about 1 GPa. The friction coefficient against Al₂O₃ was found to vary from 0.70 to 0.25. The film behavior is correlated with the microstructure and composition determined by ERD, IR spectroscopic ellipsometry, XPS and SEM.
