要：针对软脆碲锌镉晶片的传统加工工艺“游离磨料－抛光－化学机械抛光”存在的缺点，提出“固结磨料研磨－新型绿色环保抛光液化学机械抛光”新方法。固结磨料研磨工艺为：采用3000号刚玉防水砂纸，压力为17 kPa ，抛光盘与抛光垫转速均为80 r／min ，研磨时间为5 min 。新型绿色环保抛光液含有双氧水和硅溶胶，采用天然桔子汁作为 pH 值调节剂。化学机械抛光工艺为：采用自行研制的化学机械抛光液，绒毛抛光垫，抛光压力为28 kPa ，抛光盘与抛光垫转速均为60 r／min ，抛光时间为30 min 。试验结果表明，经过上述加工可获得超光滑的表面，表面粗糙度算术平均值、均方根值、峰谷值分别可以达到0.568 nm 、0.724 nm 、6.061 nm 。<br /> A strategy consisting of fixed-abrasive lapping and a developed environment-friendly solution was proposed for polishing cadmium zinc telluride（CdZn Te or CZT ） .This was to eliminate the disadvantages for conventional machining method including free abrasive lapping ,polishing and chemical mechanical polishing on CZT wafers .Waterproof paper of alumina with mesh size of 3000 was employed as fixed-abrasive lapping pad .Lapping experiments were conducted at a pressure of 17 kPa on CZT wafers .The rotation speeds for polishing plate and pad were as 80 r/min respectively ,and the duration was as 5 min during lapping experiments .The developed environment-friendly solution consisted of peroxide ,silica ,and natural orange juice that was used for pH modulator .Chemical mechanical polishing was carried out at a pressure of 28 kPa ,rotation speeds of 60 r/min for both of polishing pad and plate ,and a duration of 30 min .The experimental results show that ultra-smooth polished surfaces are achieved ,where surface roughness Ra ,root mean square（rms） ,and peak-to-valley（PV） values are as 0.568 nm ,0.724 nm ,and 6.061 nm ,respectively .<br /> 关键词：碲锌镉 固结磨料 绿色环保抛光液 化学机械抛光<br /> CdZnTe ;fixed abrasive
