Outline of Final Research Achievements

We conclude that formation of the hybrid nano particles by adsorption of nano particles such as the fullerene hydroxide and nano silica fine particles around 4nm on the core silica fine particles having larger size against the nano particles. Polishing performance as material removal rate and sauce roughness after the polishing treatment is improved at the case of hybrid nano particles in comparison with the case of single core silica particles. The hybrid nano particles might be controlled adsorption amount and kinds of nano particles by mixing conditions to meet polished substrates as several hard to work materials and metals using advanced semiconductors. By the optimization of the adsorption condition and size of the core particles, chemical action and mechanical action can be controlled only the particles without chemical reaction by the liquid of the slurry. Based on these concepts, we expect that the wide application against silicon and power semiconductor field.
