| Abstract: | Herein, based on the characteristics of higher machining efficiency and higher surface quality of ultrasonic vibration machining, a novel ultrasonic assisted fixed abrasive CMP(UFP) technique for silicon wafer was presented. The establishment of the experimental system for composite polishing was discussed in detail. In addition, the surface morphology and the material removal mechanism were investigated based on experiments and theory. Both of the theoretical model and experimental results show that with the assistance of ultrasonic vibration, the surface quality is enhanced, the material removal rate (MRR) increases, and the quality of polished surface decreases with increases of the polishing force, but the MRR increases. |
