研究了等离子体增强化学气相沉积工艺条件对氮氧化硅膜的生长厚度及折射率的影响以及氮氧化硅/氮化硅叠层膜对p型硅片的钝化效果. 实验结果表明，NH3的流量和N2O/SiH4 流量比对氮氧化硅膜的影响较大，薄膜折射率能从1.48变化到2.1，厚度从30–60 nm不等. 腔内压力和射频功率主要影响膜厚，压力越大，功率越大，沉积速率加快，生成的膜越厚. 温度对膜厚和折射率的影响可以忽略. 钝化效果显示，在有无NH3下，N2O/SiH4流量比分别为20和30时，退火后氮氧化硅/氮化硅叠层膜对p 型硅的钝化效果最好，其潜在电压和少子寿命分别为652 mV，56.7 μs 和649 mV，50.8 μs，均优于参照组氮化硅膜样品的钝化效果.
