ABSTRACT:
Chemical-mechanical polishing (“CMP”) processes performed on bodies (10), each having areas (16and18) of different depression pattern densities, are compared by correlating polishing data accumulated, for one such body, on an area (16) of one pattern density to polishing data accumulated, for that body, on an area of another pattern density for each of the CMP processes.
