Abstract
A method of forming a polysiloxane film on a substrate comprises polymerizing a siloxane monomer in a reaction chamber containing the substrate. The polymerization is catalyzed by a 30-60 W radio frequency plasma, the pressure in the reaction chamber during the polymerization is 100-400 mTorr, the residence time of the siloxane monomer in the reaction chamber is 5-120 minutes, the siloxane monomer is heated to 30-200° C. before entering the reaction chamber, and the polymerization is carried out at a temperature of 30-100° C.
