PECVD silicon carbide deposited at different temperature
PECVD silicon carbide films were deposited in a high frequency parallel-plate plasma reactor. The deposition temperatures were 250, 350 and 450 °C respectively. The concentration of species in the SiC films was determined by Rutherford backstering spectrometry (RBS). Chemical compositions were analyzed by infrared spectroscopy (IR). The IR spectra were measured from 4000 to 400 cm−1. The

Silicon nitride - Wikipedia
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si 3N 4 is the most commercially important of the silicon nitrides when referring to the term "silicon nitride". It is a white, high-melting-point solid that is relatively chemically inert
