Experimental Study of Al-Mg Alloy Chemical Mechanical Polishing in Alkaline Condition

Xu Wenzhong,Liu Yuling,Niu Xinhuan,Mu Huilai(Institute of Microelectronics,Hebei University of Technology,Tianjin 300130,China)  
CMP technology was extended to the surface processing of Al-Mg alloy.According to the features of polishing cloth and the nature of Al-Mg alloy,the polishing cloth was selected.And then the corresponding polishing solution was producted with the study of Al-Mg alloy chemical mechanical polishing in alkaline condition.Finally,three key polishing parameters of the pH,polishing pressure and slurry flow rate were optimized.The results of experiments indicate that the surface can be in a good condition when the pH value is 11.20,polishing pressure is 0.05 MPa,and the slurry flow rate is 220 ml/min.Through measureing the surface roughness with NewView 6 000,the result shows that it has reached the nanometer level.
