In this study, to examine the polishing mechanism during CMP process by ceria abrasives, we developed the mono-disperse abrasive deposition system on wafer. Polished wafer deposited with mono-sized abrasive were investigated by various analytical means. Mono-disperse abrasive deposition system could classify the uniform particle size by the mechanism using the differential electrical mobility in aerosol state of ceria slurry. We analyzed each abrasive size on wafer by means of scanning electron microscope (SEM). We found that mono-sized abrasives of slurry from 30㎚nm to 500㎚ were deposited on wafer. With the deposited 8-inch wafer, dry polishing experiment was performed to examine the surface modification. The atomic force microscope (AFM) results showed that the larger particle made the greater surface roughness. The surface roughness results were in good agreement with single particle contact analysis. The crystallographic change in sub-surface layer of particle deposited wafer was increased respect to increasing the deposited abrasive size. And the surface scratch of wafer was also checked by the wafer inspection system having 40 ㎚ resolutions. For the purpose of investigating abrasive size effects of pattern loading effect, we also used mono-disperse abrasive deposition systems. We found that initial removal shapes of various patterns depended on the abrasive sizes. In particular, the larger abrasive size was effective at pattern edge removal at the polishing beginnings. Based on scratch test and pattern loading test, we concluded the small sized ceria abrasive is effective in aspect of only micro scratches, not loading effects. Futhermore, our mono-disperse abrasive deposition system would help understanding of the polishing mechanism in mechanical aspects of CMP.
