| Abstract: | The flow field in plasma enhanced chemical vapor deposition(PECVD) reaction chamber was simulated by computational fluid dynamics(CFD) method.By varying the way pore distributed through gas distributor,distance between outlet and gas distributor panel,form and angle of outlet,and gas pressure,the corresponding gas velocity,flow filed in the reaction chamber was calculated.The geometric structure and inflow pattern of a PECVD reactor was improved in order to provide steady and uniform flow field and thus improve the quality of thin films.The gas distributor is manufactured and improve the gas distribution in the actual equipment. |
