Abstract:
A chemical vapor deposition method for producing fluorinated hydrogenated silicon carbide films comprisingintroducing a reactive gas mixture comprising a silicon containing compound and a fluorocarbon compound into a deposition chamber containing a substrate inducing a reaction between the silicon containing compound and fluorocarbon compound at a temperature of 25Â° C. to 500Â° C. to provide a film comprising hydrogen, silicon, carbon and fluorine wherein the film has the formula SiaCbHcFd wherein the ratio of b:a is in the range of about 1:1 to about 10:1; c is greater than 0 to up to about 40 atomic % based on all the atoms in the film and d is in the range of 0.01 up to 15 atomic % based on all the atoms in the film.
