Abstract:
1. A process for forming a film on a substrate comprising: providing a linear alkylalkoxysilane precursor of the formula: wherein R, R″ and R′″ are each individually selected from the group consisting of methyl, ethyl or vinyl; R′ is selected from the group consisting of hydrogen, methyl, ethyl or vinyl; and x, z and a are each individually 1-3 and y is 0-2, wherein x+y+z+a=4; forming a film on a substrate using chemical vapor deposition reaction of the precursor where a residence time of a flow of the precursor in the reaction is less than or equal to 85 msec, wherein the density of the film is greater than 1.5 g/cc and a dielectric constant is less than 6.0.
