Abstract

The use of a variable duty cycle, pulsed RF plasma, in lieu of a continuous wave (CW) plasma, is employed for plasma polymerization of diverse monomers. The monomers discussed in this work include vinyltrimethylsilane, perfluoro-2-butyl tetrahydrofuran, and dichloro-methane. For each of these monomers, progressive changes in the molecular composition of the plasma deposited films are observed with systematic changes in the pulsed RF duty cycle employed during the deposition step, all other plasma variables being maintained constant. Significantly different film chemistry and deposition rates are observed in contrasting CW with equivalent wattage pulsed plasmas. Overall, the results obtained indicate that the use of variable duty cycle pulsed RF plasmas offer a promising approach to molecular tailoring of the film chemistry which occurs during plasma polymerizations.
