Abstract
A method for depositing an amorphous carbon hardmask film includes arranging a substrate in a processing chamber, supplying a carrier gas to the processing chamber, supplying a hydrocarbon precursor to the processing chamber, supplying fluorine precursor from a group consisting of WF, NF, SF, and Fto the processing chamber, one of supplying plasma to the processing chamber or creating plasma in the processing chamber, and depositing an amorphous carbon hardmask film on the substrate. Fluorine from the fluorine precursor combines with hydrogen from the hydrocarbon precursor in gas phase reactions.
