摘　　要：采用化学机械抛光（CMP）的方法,自制抛光液作为研磨介质,对（50×50×1.5）mm3硒化锌（ZnSe）晶片抛光。通过分析抛光液的pH值、抛光盘转速、抛光液的磨料浓度、压力、抛光时间和抛光液流量等参数对CMP的影响,组合出最佳工艺参数,并通过原子力显微镜和平晶测试方法对最佳工艺参数获得的ZnSe晶片进行测试,实验结果显示,ZnSe晶片抛光后的表面粗糙度Ra为0.578 nm,平面面形误差小于1.8μm。
The ZnSe wafer（50 × 50 × 1. 5） mm3 was polished by chemical mechanical polishing（CMP）method using self-made abrasive as grinding medium. After the effects of the parameters such as the pH value of the polishing liquid on the CMP had been analyzed,rotating rate,the concentration of abrasive,pressure,polishing time and a flow rate of polishing liquid,the best process parameters could be obtained. The ZnSe wafer after polishing with the best process parameters was detected by an atomic force microscope and optical flat. The experimental results show that the surface roughness is 0. 578 nm and the optimal flatness is less than 1. 8 μm.
