  • Patent number: 7201636
    Abstract: A substrate is chemical mechanical polished with a high-selectivity slurry until the stop layer is at least partially exposed, and then the substrate is polished with a low-selectivity slurry until the stop layer is completely exposed.
    Type: Grant

  • Patent number: 6435942
    Abstract: A substrate is chemical mechanical polished first with a single layer hard polishing pad and a high-selectivity slurry until a first endpoint is reached, and then with a soft polishing pad and a low-selectivity slurry until a second endpoint is reached. Dishing is reduced when low-selectivity slurry is used at the second polishing step. Low Within-Wafer-Non-Uniformity is achieved by using a single layer hard pad at low pressure at the first polishing step.
