1. A method of preparing a low-k dielectric on an integrated circuit substrate, the method comprising:

  • forming a dielectric film on the substrate, the film formed by contacting the substrate with ethynyltrimethylsilane and a carrier gas comprising CO2 in a PECVD reactor processing chamber operated at a temperature of between about 300 and 425°

    C., a pressure of between about 2 and 7 Torr and a HF RF power of at least about 125 W.
