Development of a reliable mechanical decapsulation procedure for an IC process incorporating Cu and organic passivation layers resulted in a better understanding of the polishing process. The improved polishing technique --Deterministic Polishing-- is an adaptation of an advanced polishing technology employed by the optics industry to fabricate highly accurate optical elements. These results can be applied to a broad class of polishing applications.
