    摘要: Embodiments described herein generally provide a method for processing metals disposed on a substrate in a chemical mechanical polishing system. The apparatus advantageously facilitates efficient bulk and residual conductive material removal from a substrate. In one embodiment a method for chemical mechanical polishing (CMP) of a conductive material disposed on a substrate is provided. A substrate comprising a conductive material disposed over an underlying barrier material is positioned on a first platen containing a first polishing pad. The substrate is polished on a first platen to remove a bulk portion of the conductive material. A rate quench process is performed in order to reduce a metal ion concentration in the polishing slurry. The substrate is polished on the first platen to breakthrough the conductive material exposing a portion of the underlying barrier material.

    摘要: A polishing method includes simultaneously polishing a first substrate and a second substrate on the same polishing pad, storing a default overpolishing time, determining first and second polishing endpoint times of the first and substrates with the in-situ monitoring system, determining a difference between the first and second polishing endpoint times, and determining whether the difference exceeds a threshold. If the difference is less than the threshold, then an overpolishing stop time is calculated and polishing of the first substrate and the second substrates is halted simultaneously at the overpolishing stop time. If the difference is greater than the threshold, then first and second overpolishing stop times that equal the first and second endpoint times plus the default overpolishing time are calculated, and polishing of the first and second substrates is halted at the first and second overpolishing stop times, respectively.

    摘要: A method of controlling polishing includes storing a library having a plurality of reference spectra, polishing a substrate, measuring a sequence of spectra of light from the substrate during polishing, for each measured spectrum of the sequence of spectra, finding a best matching reference spectrum using a matching technique other than sum of squared differences to generate a sequence of best matching reference spectra, and determining at least one of a polishing endpoint or an adjustment for a polishing rate based on the sequence of best matching reference spectra. Finding a best matching reference spectrum may include performing a cross-correlation of the measured spectrum with each of two or more of the plurality of reference spectra from the library and selecting a reference spectrum with the greatest correlation to the measured spectrum as a best matching reference spectrum.
