摘要
High quality amorphous silicon nitride films have been deposited, without substrate heating, using a sputtering-type electron cyclotron resonance (ECR) microwave plasma. The compositional and structural characterizations have been made by means of a Fourier transform infrared (FT-IR) spectrometer and an ellipsometer. The correlation between the microstructure of a-SixNy films and nitrogen gas fraction relative to (N-2/Ar) is discussed. In-situ Fourier transform infrared reflection absorption spectroscopy (ISFT-IRRAS) has been used to study the properties of a-SixNy/Si interface. The results from ISFT-IRRAS monitoring indicate that the broadening of a Si-N stretching vibration mode, induced by interface stress, decreases with increased film thickness.
