Abstract
Methods for depositing hardmask materials and films, and more specifically, for depositing phosphorus-doped, silicon nitride films are provided. A method of depositing a material on a substrate in a processing chamber includes exposing a substrate to a deposition gas in the presence of RF power to deposit a phosphorus-doped, silicon nitride film on the substrate during a plasma-enhanced chemical vapor deposition (PE-CVD) process. The deposition gas contains one or more silicon precursors, one or more nitrogen precursors, one or more phosphorus precursors, and one or more carrier gases. The phosphorus-doped, silicon nitride film has a phosphorus concentration in a range from about 0.1 atomic percent (at %) to about 10 at %.
