英文摘要：

SH_4 and O_2 were selected as the reaction gas,silicon oxide films were prepared by inductively coupled plasma- enhanced chemical vapor deposition（ ICPECVD） technology. The influence and significance of the three key process parameters including reaction chamber pressure,substrate temperature and RF power on the deposition rate of silicon oxide films were investigated by the orthogonal experiment design method. The experimental results show the influence sequence on the deposition rate of silicon oxide films presents as reaction is chamber pressure 〉RF power 〉substrate temperature and the influence principle of different factors on the deposition rate of silicon oxide films was discussed.
