摘要
采用化学机械抛光方法,在新型智能抛光机上用自制的抛光液对铌酸锂晶片进行抛光。结果证明选择适当的参数后可以得到一种超平滑表面,几乎无损伤层,且有较高的面形精度和加工效率。采用扫描探针显微镜(SPM)获得了铌酸锂晶片表面微观形貌,并测定了损伤层,分析了铌酸锂晶片的表面形成机理及其表面加工缺陷和损伤层的成因。
In this paper,the Chemical Mechanical Polishing method has been applied to th e experiment research,the test were carried on a new brainpower type super pre cision polishing machine,and the LiNbO 3 wafers were polished in a home-made slurry.Studies have shown that this is an attractive method if parameters were properly selected;We can gain a nearl y none-damaged layer,super smooth surface.In the test,the scanning probe mic roscope(SPM)were used to gain photos of the microcosmic surface of LiNbO 3 wafer,We also an a-lyzed the polishing mechanism on LiNbO 3 wafer,and the cau sa tion of it’s surface machining flaws and the damaged layer.
