ABSTRACT:
Embodiments of the invention as directed to supporting a polishing pad that can be easily replaced. In one embodiment, a method for polishing an object comprises coupling a polishing head to a substrate for holding a polishing pad which is smaller in area than the object; applying a resilient mechanical force to the perimeter of the substrate with the polishing head to hold the substrate in place during a polishing operation; placing the polishing pad in contact with the object; and rotating the polishing pad with the polishing head.
