Method for optimizing the planarizing length of a polishing pad
A method for optimizing the planarizing length of a polishing pad is disclosed that includes forming a substantially constant network of islands and trenches into a first side of a polishing pad. The trenches are formed to a pre-determined distance apart. The polishing pad is fit to a chemical-mechanical polishing system. A surface layer of a semiconductor wafer is planarized with the first side of the polishing pad. Upon completion of the polishing process, the planarized wafer surface layer is observed. If the wafer surface layer is planarized to an amount outside of a set target polishing range, the distance between the trenches on the first side of the polishing pad is uniformly decreased. The above steps are repeated until the wafer surface layer is planarized to an amount within the set target polishing range.
