Methods for forming silicon containing films using silylamine moieties are disclosed. In some embodiments, silylamine moieties are employed to deposit silicon-nitrogen, silicon-oxygen, or silicon-nitrogen-oxygen materials at temperatures of less than 550°C. In some embodiments methods are practiced within process chambers adapted to contain a single substrate as well as within process chambers adapted to contain a plurality of substrates, where the silylamine moieties are conveyed to the chambers in across flow type manner.
