摘要： Embodiments of the present invention generally relate to methods for chemical mechanical polishing a substrate. The methods generally include coupling a first substrate to be polished to a dummy substrate, and removing a portion of the backside of the first substrate to reduce the thickness of the first substrate. The first substrate and the dummy substrate are positioned in a carrier head assembly comprising an inflatable membrane and a support ring. The first substrate is placed in contact with a polishing pad to reduce the surface roughness of the backside of the first substrate. The support ring restricts lateral movement of the inflatable membrane to prevent the first substrate from contacting an interior surface of the carrier head assembly. The support ring is sized to allow vertical movement of the inflatable membrane within the carrier head assembly.
