| Abstract: | The principle of the ultrasonic elliptic vibration produced by polishing tool is introduced and elliptic motion characteristics of the polishing tool are tested.Then the working mechanism of ultrasonic elliptic vibration for improving the polishing quality is analyzed.Finally,based on the above established testing system of ultrasonic elliptic vibration assisted polishing,experimental investigations are conducted.Experimental results show that the silicon wafer polishing with the new method on surface quality,and material remove rate are better than that of without polishing. |
| Keywords: | ultrasonics elliptic vibration chemically mechanical polishing integrate polishing |
