Presently, the products of functional ceramic are widely applied in the light & mechatronics fields such as communication, aeronautic and astronautic engineering, military affairs and home-use electrical appliance etc. It’s performance of working is mainly determined by the physical performance of the surface. And therefore the roughness and the affected layer’s depth of the final processing surface have a direct influence to the performance of the device. It is obvious that how to guarantee the processing quality of functional ceramic is a kernel problem whether it can achieve the purpose of application or not. Ultra-precision planarization is usually as the final processing method of functional ceramic substrates, and the mirror surface of Ra 0.01~0.002 μm can be obtained by ultra-precision polishing. For the ultra-precision planarization processing of functional ceramic material, simplex chemical or mechanical polishing method is very difficult to achieve the technic demands, and furthermore various defects of processing exist in the surface of crystal after planarization. However, chemical mechanical planarization (CMP) which has emerged recently as a new indispensable processing technique for higher degree planarization of functional ceramic is be able to satisfy the processing requests from the aspects of processing performance and rate. The current paper systematically introduces the processing course of functional ceramic by using chemical mechanical planarization. In addition, material removal mechanism is analyzed, and the choosing of processing conditions and components and effect of polishing slurry are discussed. Then the present research status and development trend of CMP technology for functional ceramic are discussed. Finally the current existing main questions and their solutions are presented. 展开更多
