通过改变RIE 刻蚀参数如:射频功率、腔体压强、气体流量、气体组分等可以调整两种刻蚀过程所占比重
因此 ,优化刻蚀工艺就是要选择最优的刻蚀参数组合,在减小刻蚀损伤的同时保证光滑的刻蚀表面和一定的刻蚀速率以及方向性
本文归纳总结了常见薄膜的刻蚀优化方法

By changing the RIE etching parameters: such as, RF power, cavity pressure, gas composition, can adjust the two etching process
Therefore, optimize the etching process is to select the optimal etching parameters combination, reducing the etching damag
