    摘要: A polishing pad is provided comprising an upper surface and a lower surface, substantially parallel to one another, wherein the pad has enhanced flexibility produced by scoring of either or both surfaces. The pad thickness is generally greater than 500.mu.. The scoring creates slits having a depth of less than 90% of the thickness.

    摘要: The present invention provides a chemical mechanical polishing method for the planarization of shallow trench isolation structure and other integrated circuit structures. The method of the invention comprises the steps of providing a substrate having a plurality of patterned regions and polishing the substrate with a chemical mechanical polishing slurry comprising small abrasive particles having a mean diameter of between about 2 and 30 nm and large abrasive particles having a mean diameter of between 2 and 10 times larger than the mean diameter of the small abrasive particles. The chemical mechanical polishing slurries can also include viscosity additives and etchants for use in the invention.
