More Information
Summary:Embodiments described and discussed herein provide methods for depositing silicon nitride materials by vapor deposition, such as by flowable chemical vapor deposition (FCVD), as well as for utilizing new silicon-nitrogen precursors for such deposition processes. The silicon nitride materials are deposited on substrates for gap fill applications, such as filling trenches formed in the substrate surfaces. In one or more embodiments, the method for depositing a silicon nitride film includes introducing one or more silicon-nitrogen precursors and one or more plasma-activated co-reactants into a processing chamber, producing a plasma within the processing chamber, and reacting the silicon-nitrogen precursor and the plasma-activated co-reactant in the plasma to produce a flowable silicon nitride material on a substrate within the processing chamber. The method also includes treating the flowable silicon nitride material to produce a solid silicon nitride material on the substrate.
