    摘要: A composition and method of preparation, to provide silane compounds that are free of chlorine. The compounds are hexakis(monohydrocarbylamino)disilanes with general formula (I) ((R)HN)3—Si—Si—(NH(R))3  (I) wherein each R independently represents a C1 to C4 hydrocarbyl. These disilanes may be synthesized by reacting hexachlorodisilane in organic solvent with at least 6-fold moles of the monohydrocarbylamine RNH2 (wherein R is a C1 to C4 hydrocarbyl). Such compounds have excellent film-forming characteristics at low temperatures. These films, particularly in the case of silicon nitride and silicon oxynitride, also have excellent handling characteristics.

    摘要: (Problem) To provide a method for the production of silicon nitride and silicon oxynitride films by CVD technology, wherein said method provides acceptable film-deposition rates even at lower temperatures and is not accompanied by the production of large amounts of ammonium chloride. (Solution) Use of a hydrocarbylaminodisilane compound with the formula (R0)3—Si—(R0)3 (I) {each R0 is independently selected from the hydrogen atom chlorine atom, and —NR1(R2) groups (wherein R1 and R2 are each independently selected from the hydrogen atom and C1 to C4 hydrocarbyl with the proviso that R1 and R2 may not both be the hydrogen atom) and at least one R0 is the —NR1(R2) group} as a precursor for silicon nitride and silicon oxynitride.
