Abstract
A method of processing a substrate is provided including flowing a deposition gas comprising a hydrocarbon compound and a dopant compound into a process volume having a substrate disposed positioned on a substrate support. The process volume is maintained at a pressure of about 0.5 mTorr to about 10 mTorr. The method includes generating a plasma at the substrate by applying a first RF bias to the substrate support to deposit a doped diamond-like carbon film on the substrate. The doped diamond-like carbon film includes about 5 at. % to about 25 at. % of dopant and a first stress property. The method includes annealing the doped diamond-like carbon film at about 220° C. to about 450° C. to form an annealed film. The annealed film includes a second stress property. The second stress property having an absolute value less than or within 10% the first stress property.
