Abstract

A method of forming a carbon hard mask includes generating a radio frequency plasma including carbon-based ions by supplying continuous wave radio frequency power to a plasma processing chamber. The carbon-based ions have a first average ion energy. The method further includes adjusting the first average ion energy of the carbon-based ions to a second average ion energy by supplying continuous wave direct current power to the plasma processing chamber concurrently with the continuous wave radio frequency power and forming a carbon hard mask at a substrate within the plasma processing chamber by delivering the carbon-based ions having the second average ion energy to the substrate.
