    摘要: A polishing pad for polishing semiconductors and other planar substrates in the presence of a slurry comprising abrasive particles and a dispersive agent is disclosed. The polishing pad includes a soluble component within a polymer matrix component. The soluble component includes particles soluble in the slurry sufficiently to provide a void structure in the polishing surface of the pad. The void structure enhances the polishing rate and uniformity by increasing the mobility of the abrasive particles while reducing scratching of the polished surface. Additives that further enhance polishing and/or assist in the removal of residues generated during polishing, such as surfactants and removers, are optionally incorporated in the soluble particles or topographically coated on the soluble particles.

    摘要: A method of making a polishing pad having a body comprising fibers embedded in a matrix polymer formed by a reaction of polymer precursors. The fibers define interstices, and the precursors fill these interstices substantially completely before completion of the reaction. The method comprising placing the fibers and the precursors in a cavity of a mold for shaping the polishing pad; applying a differential pressure across a mold cavity, where the differential pressure and the amount of precursors are sufficient to cause the precursors to fill the interstices substantially completely before completion of the reaction; and applying sufficient heat to the mold to at least partially cure the polishing pad by causing the precursors to react.

    摘要: A polishing pad for polishing semiconductors and other planar substrates in the presence of a slurry comprising abrasive particles and a dispersive agent is disclosed. The polishing pad includes a soluble component, preferably fibrous, within a polymer matrix component. The fibrous component includes fibers soluble in the slurry sufficiently to provide a void structure in the polishing surface of the pad. The void structure enhances the polishing rate and uniformity by increasing the mobility of the abrasive particles while reducing scratching of the polished surface. Additives that further enhance polishing and/or assist in the removal of residues generated during polishing, such as surfactants and removers, are optionally incorporated in the fibrous substance or topographically coated on the fibrous substance.
