Original Abstract

Elastic thin films of vinyltriethoxysilane were prepared by plasma-enhanced chemical vapor deposition using an RF (13.56 MHz) helical coupling plasma system. An effective power density ranging from 8 . 10-4 to 0.3 W cm-3 was used to control the Young's modulus of films to a range of 3.7 - 11.3 GPa. The modulus decreased slightly with the film thickness varying from 80 nm to 1.5 microns for films prepared under the same deposition conditions. The hardness of films (0.7 - 2.1 GPa) was proportional to the Young's modulus with a relatively high ratio of 0.185 associated with a higher mean compressive elastic strain with respect to other groups of plasma polymers (0.059 - 0.115). Thin films exhibited an abrupt increase in hardness at the film surface related to post-deposition oxidation.
