Abstract

A method for forming carbon doped oxide layers by chemical vapor deposition using a source gas that includes: (a) an alkyl-alkoxysilane having the formula (R.sup.1).sub.n (R.sup.2 O).sub.4-n Si where R.sup.1 and R.sup.2 are lower alkyl groups and n is an integer between 0 and 3, inclusive, with the proviso that when R.sup.1 and R.sup.2 are methyl groups, n is not equal to 2; (b) a fluorinated alkoxysilane having the formula (R.sup.3 O).sub.n SiF.sub.4-n where R.sup.3 is a lower alkyl group and n is an integer between 1 and 3, inclusive, or a combination thereof.
