Abstract

Amorphous silicon carbonitride (a-SiCN) films were synthesized by ion enhanced radio-frequency (rf) magnetron sputtering from a Si4C target using a mixture of Ar and N2 gases. The oxidation resistance of the films was investigated in an oxygen atmosphere over the temperature range of 0-1000 °C. X-ray photoelectron spectroscopy showed that the a-SiCN films exhibited a well-defined Si-C-N bonding structure. The composition, density, hardness, and stress were uniquely characterized with respect to the average energy per deposited atom. Under optimum deposition conditions a-SiCN films can be prepared to exhibit high density (>2.6 g cm-3), high hardness (>25 GPa), and enhanced oxidization resistance at temperatures up to 800 °C.
