    摘要: A method and apparatus for conditioning a fixed-abrasive polishing pad used in chemical mechanical planarization of semiconductor wafers is described. The apparatus includes a conditioning member having a smooth surface. The method includes providing a conditioning member having a smooth surface, pressing the conditioning member against the fixed-abrasive polishing pad, and moving the fixed-abrasive polishing pad. In one embodiment, the method further comprises moving the conditioning member perpendicular to the direction of movement of the fixed-abrasive pad to compensate for variations in amounts of exposed abrasive on the fixed-abrasive pad.

    摘要: A CMP polishing pad improves overall material removal rate uniformity by combining multiple polishing pad sections in a serially linked manner, where the polishing pad sections are characterized by at least two different material removal rate profiles. The polishing pad is designed by determining a wafer polishing profile for each of a group of polishing pads where each polishing pad has a unique groove configuration, determining a combination of polishing pad segments, each of the segments constructed with one of the unique groove configurations, that will combine to achieve an improved uniformity in the polishing profile, and manufacturing a polishing pad having pad sections corresponding to the analytically determined pad sections.

    摘要: A method and apparatus for rotating wafers in a double sided scrubber where a rotating roller imparts rotary motion to a semiconductor wafer during a double sided cleaning process. The rotating roller and wafer contact at their outer edges and the friction between their outer edges causes the wafer to rotate. The roller has an outer edge with a groove in which the wafer edge is pinched. Treads or grooves extending from the groove channel liquids away from the groove to prevent wafer slippage when rotating and cleaning solutions are applied to the wafer.
