Abstract
An apparatus for chemically-mechanically polishing a semiconductor wafer comprises a receiving surface attached with a frame; a loading mechanism in contact with the receiving surface, the loading mechanism being configured to load measured portions of a wafer-polishing member containing a fixed abrasive onto the receiving surface; a reciprocation device attached with at least a portion of the receiving surface, the reciprocation device being powered to move the receiving surface in a linear, bi-directional motion; and a wafer holder positioned to releasably hold a wafer adjacent to the receiving surface. Methods of chemically-mechanically polishing semiconductor wafers are also provided.
