中文摘要：
针对用于制备非晶硅薄膜的PECVD设备反应室的流体场进行了模拟仿真,并实验制备了相对应条件下的非晶硅薄膜,利用台阶仪完成了对薄膜厚度的测量,对比仿真结果,发现薄膜的厚度分布情况与基片表面附近的气流分布情况密切相关,获得均匀性优于2.5%非晶硅薄膜。
英文摘要：
The reaction chamber of PECVD equipment was simulated by using Fluent software and amorphous silicon thin films were prepared by PECVD.The film thickness was measured by step apparatus,and by comparing with the simulation results,it indicates that the thickness distribution and airflow distribution of the substrate surface near the film is closely related,and the intake flow of the reaction is positively correlated with the chamber deposition rate.The amorphous silicon thin films with the uniformity higher than 2.5% were obtained.
