摘　　要：介绍了一种在行星式双面磨抛设备上对压电陶瓷圆片进行单面研磨和抛光的工艺。在加工过程中,使用了自制的全水溶性粘接剂来粘接晶片,实现了圆片单面所有磨抛加工流程都在双面磨抛设备上进行。采用自制化学腐蚀液分段腐蚀控制圆片形貌(翘曲度)的变化,中间研磨工序优化介质控制表面粗糙度和划道、SiO2胶体化学机械抛光去除亚损伤层,获得了高品质的铝钛酸铝压电陶瓷(PZT)单面抛光圆片。A single side grinding and polishing process of piezoelectric ceramics wafer on a planetary double side grinding and polishing equipment is presented in this paper.The self prepared full water solubility adhesive is used to bond the wafers in the processing,and all the single side grinding and polishing processes of wafer are carried out on the double sided grinding and polishing equipment.The change of wafer morphology （warp） is step controlled by the self prepared chemical etching solution,the surface roughness and path of the wafers are controlled by the optimal medium in the intermediate grinding process,the sub damaged layer of wafers are removed by the chemical mechanical polishing with SiO2 colloid.Finally,the high quality PZT ceramic single side polished wafers are obtained.
