  • Polishing pad and method of use thereof
    Patent number: 6287174
    Abstract: A polishing pad for semiconductor wafers having a polishing surface surrounding at least one wafer non-contact region and a method for disengaging a wafer with the polishing pad is disclosed. The wafer non-contact region(s) are located and dimensioned to provide a location for positioning the wafer prior to disengagement, thereby reducing the cohesion force of the slurry resisting the force used for lifting the wafer from the plane of the polishing pad surface. The invention provides safe disengagement of the wafer with the polishing pad, and is especially useful for polishing apparatus employing vacuum retaining means for holding the wafer.
