We compared the material removal rates of the traditional CMP and the fine atomizing CMP.
The necessary conditions for polishing were as follows: The pressure of polishing is 7PSI; the speed of polishing pad is 55r/min; the time of polishing is 5min; the flow velocity of polishing slurry in the traditional CMP is 100ml/min and in the fine atomizing CMP is 10ml/min; the materials are monocrystalline silicon chips (20mm×20mm).
