    摘要: Apparatus and methods adapted to polish an edge of a substrate include (1) a polishing tape having a polishing surface and a second surface and (2) a polishing arm having a longitudinal axis and adapted to force the polishing surface of the polishing tape into contact with an edge of a substrate. The polishing arm includes i) a polishing head adapted to contact the second surface of the polishing tape, ii) a rocker arm coupled to the polishing head and adapted to rotate the polishing head around the longitudinal axis of the polishing arm and iii) a load arm extending adjacent to the rocker arm and adapted to move the polishing head in a direction perpendicular to the longitudinal axis of the polishing arm. Numerous other aspects are provided.

    摘要: A retaining ring for electrochemical mechanical processing is described. The ring has a conductive portion having an upper surface and a lower surface and an insulating portion. The insulating portion has one or more openings extending therethrough, exposing the lower surface of the conductive portion. An upper surface of the insulating portion contacts the lower surface of the conductive portion. In an electrochemical mechanical polishing process, the retaining ring can be biased separately from a substrate being polished.

    摘要: A method and apparatus for electrically biasing a substrate in an electrochemical processing system is generally provided. In one embodiment, an apparatus for electrochemical processing includes a polishing pad and a conductive element disposed therein. The polishing pad has an upper surface adapted to support a substrate thereon during processing. The conductive element disposed in the polishing pad is movable between a first position having at least a portion of the conductive element exposed above the upper surface and a second position below the upper surface, wherein the conductive element is magnetically biased towards the first position.
