摘要: 用红外光谱、质子核磁共振谱对以SiH4/NH3/N2混合气体为源、用等离子体增强化学气相淀积法淀积的非晶氢化氮化硅(a-SiNx:H)薄膜进行了分析,结果表明膜中H以Si-H和N-H形式存在,均呈集聚和疏散两种分布状态,衬底温度影响氢的总量和分布均匀性,射频功率显著影响[N-H]/[Si-H],退火后氢仍呈集聚和疏散两种分布.

Abstract: Amorphous hydrogenated silicon nitride (a-SiNx:H) films deposited by plasma-enhanced chemical vapor deposition using SiH4/NH3/N2 mixtures are analysed by infrared and proton nuclear magnetic resonance. The results demonstrate that hydrogen in the films exists in the forms of Si-H and N-H, both of which are in the state of cluster and dispersion. Substrate temperature effects on total hydrogen density and homogeneity,rf power controls the ratio of[N-H]/[Si-H]; after annealing, the spatial distribution of hydrogen is still in cluster and dispersion phase.
