| 摘 要： | 以大面积喷淋式平板电极甚高频等离子体增强化学气相沉积(VHF-PECVD)反应室为研究对象,利用FlexPDE和CFD-ACE+商业软件,对反应室电极间的电场和流场分布进行了数值模拟。根据数值模拟结果可知:对于大面积喷淋式平板电极VHF-PECVD反应室,电极间气体流速分布呈现管流特征,而气压分布和电场分布具有类似的分布规律,即在大面积电极中央区域电场较强气压较高,而电极边缘区域电场较弱气压较低;另外,反应室采用喷淋式平板电极进行反应气体馈入,气体总流量、工作气压和电极间距是调节电极间气压分布均匀性的重要参量,采用大电极间距、高工作气压,以及小的气体总流量有助于获得均匀的气压分布。

| Abstract: | The VHF-PECVD(very high frequency plasma enhanced chemical vapor deposition) reactor with large-area spraying parallel-plate electrodes was investigated via a numerical simulation of the distributions of the electric field and flow field between the electrodes by use of the commercial software FlexPDE and CFD-ACE +.The numerical simulation results showed that the distribution of gas flowrate between such electrodes presents the characteristics of pipe flow and both the electric field and gas pressure are di... |
