Abstract:
A method of synthesizing a ternary Si.sub.x C.sub.y N.sub.z compound comprising a predominantly carbon-nitride network in crystalline form on a crystalline Si substrate, wherein the chemical composition of the ternary compound is in the range of Si: (x=) 15-20 at. %, C: (y=) 30-40 at. % and N: (z=) 45-55 at. %, which comprises perform ing plasma enhanced deposition of a mixture of methane, silane, nitrogen and hydrogen containing gases, at flow rates of 5-25, 0.4-0.8. 70-90 and 60-80 sccm, respectively, for said gases, wherein the substrate is held at a temperature of between 800 and 1200.degree. C. to produce said ternary crystalline compound.
