  • Patent number: 7429210
    Abstract: A polishing article and method for manufacturing a polishing article for use in a chemical mechanical polishing process is disclosed. The polishing article has a plurality of polishing material tiles separated by grooves formed in or through a polishing material and may be adhesively bound to a base film. The polishing article may include various polygonal tiles and oval shapes formed in the polishing material which allow enhanced slurry retention and ease in rolling from a polishing material supply roll and onto a take-up roll in a web type platen assembly. The polishing article may also include an upper carrier film adapted to minimize delaminating stress placed in an area of the polishing article that is not adapted for polishing. A method and apparatus for manufacturing the various embodiments of the polishing article and a replacement supply roll are also disclosed.

  • Publication number: 20070197141
    Abstract: A polishing apparatus is described. The polishing apparatus includes a rotatable platen, a drive mechanism to incrementally advance a polishing sheet having a polishing surface in a linear direction across the platen, a subpad on the platen to support the polishing sheet, the subpad having a groove formed therein, and a vacuum source connected to the groove of the subpad and configured to apply a vacuum sufficient to pull portions of the polishing sheet into the groove of the subpad to induce a groove in the polishing surface.

  • Publication number: 20070117500
    Abstract: A polishing article and method for manufacturing a polishing article for use in a chemical mechanical polishing process is disclosed. The polishing article has a plurality of polishing material tiles separated by grooves formed in or through a polishing material and may be adhesively bound to a base film. The polishing article may include various polygonal tiles and oval shapes formed in the polishing material which allow enhanced slurry retention and ease in rolling from a polishing material supply roll and onto a take-up roll in a web type platen assembly. The polishing article may also include an upper carrier film adapted to minimize delaminating stress placed in an area of the polishing article that is not adapted for polishing. A method and apparatus for manufacturing the various embodiments of the polishing article and a replacement supply roll are also disclosed.
