aminosilanes derived from hexamethyldisilazane as chemical vapor deposition (CVD) precursors for SiCxNy and relevant films have been reported and characterized by 1H, 13C, and 29Si NMR as well as by EI-MS and elemental analysis, where necessary. Thermal stability, transport behavior and vapor pressures were evaluated by simultaneous thermal analyses (STA). Chemical vapor deposition was accomplished in
图形摘要摘要 衍生自六甲基二硅氮烷的两种氨基硅烷作为 SiCxNy 和相关薄膜的化学气相沉积 (CVD) 前体已有报道,并在必要时通过 1H、13C 和 29Si NMR 以及 EI-MS 和元素分析进行表征。通过同步热分析 (STA) 评估热稳定性、传输行为和蒸汽压。化学气相沉积在热壁 CVD 反应器系统中完成,以进一步证明这些化合物作为 CVD 前体的能力。最重要的是,生长薄膜的表征(XPS)证明薄膜的组成可以通过前体的分子结构来控制。结果表明了未来为 SiCxNy 和相关薄膜设计 CVD 前体的策略。
