摘要
用透射电镜、扫描电镜对GaAs材料加工工艺中的表面损伤层进行了观察和检测。结果切片损伤层深度≤50μm、双面研磨损伤层深度≤15μm、机械化学抛光损伤层深度(腐蚀前)<1.2μm。分析了损伤结构及其引入的因素。
The damage layer caused in processing on the surface of GaAs wafer was observed and determined by TEM and SEM. The results show that the thickness of the damage layer on sliced, lapped and polished wafers are ≤50 μm, ≤15 μm and ≤1.2 μm respectively. The structure and the caused mechanism of the damage layer on GaAs wafer were studied.
