Abstract: Embodiments relate to a polishing pad, which comprises a window having a hardness similar to that of its polishing layer. Since the polishing pad comprises a window having a hardness and a polishing rate similar to those of its polishing layer, it can produce an effect of preventing scratches on a wafer during a CMP process. In addition, the polishing layer and the window of the polishing pad have a similar rate of change in hardness with respect to temperature, so that they can maintain a similar hardness despite a change in temperature during the CMP process.

Abstract: A buffing and polishing member has an uncompressed monolithic body of foam material having slits from an outside surface toward and less than a distance to a rotational axis of the body. The slits, on circumferential spaced planes, extend generally radially from the outside surface toward and less than a distance to the rotational axis to define a plurality of foam fingers and an unslit center portion. A fastening mechanism holds the center portion of the slit foam body in a compressed state along the rotational axis such that the uncompressed outer ends of the foam finger define a spherocylinder.
