A theoretical study on rate accelerator for Si CMP

A theoretical analysis of the roles of rate accelerator for Si CMP processes is of paramount importance in the design of more effective slurries. In this study, the possible factors related to the removal rate of Si were analyzed by means of computational chemistry methods. As a result, it was found that there exists the relation between the ratios of the experimental removal rates and the ratios of the calculated bond strengths of Si-Si.
