ABSTRACT |
Silicon dioxide thin film has been grown by a chemical vapor deposition (CVD) technique using SiH4, and O2 gaseous mixture on a silicon substrate. The experimental results indicated that the deposition rate as a function of the input ratio (O2/SiH4) shows two regions, increasing region and decreasing region. Also the deposition rate increases with increasing the deposition temperature. The microstructure of deposited silicon dioxide films is amorphous. The experimental results of infrared absorption spectrums indicate that Si-H and Si-OH bond increase with decreasing input ratio, but Si-O bond is independent on the input ratio. The interfacial charge of deposited silicon dioxide decreases with increasing input ratio. |
