A method is provided for forming an amorphous carbon layer, deposited on a dielectric material such as oxide, nitride, silicon carbide, carbon doped oxide, etc., or a metal layer such as tungsten, aluminum or poly-silicon. The method includes the use of chamber seasoning, variable thickness of seasoning film, wider spacing, variable process gas flows, post-deposition purge with inert gas, and post-deposition plasma purge, among others, to make the deposition of an amorphous carbon film at low deposition temperatures possible without any defects or particle contamination.
