Abstract: A chemical mechanical polishing method and apparatus provides a deformable, telescoping slurry dispenser arm coupled to a dispenser head that may be arcuate in shape and may also be a bendable telescoping member that can be adjusted to vary the number of slurry dispenser ports and the degree of curvature of the dispenser head. The dispenser arm may additionally include slurry dispenser ports therein. The dispenser arm may advantageously be formed of a plurality of nested tubes that are slidable with respect to one another. The adjustable dispenser arm may pivot about a pivot point and can be variously positioned to accommodate different sized polishing pads used to polish substrates of different dimensions and the bendable, telescoping slurry dispenser arm and dispenser head provide uniform slurry distribution to any of various wafer polishing locations, effective slurry usage and uniform polishing profiles in each case.

Abstract: A chemical mechanical polishing (CMP) apparatus provides for polishing semiconductor wafers and for conditioning the polishing pad of the CMP apparatus using multiple conditioning disks at the same time. The conditioning disks may be moved together or independently along the surface of polishing pad to condition the entire surface of the rotating polishing pad.
