Zusammenfassung: | The polishing pad comprises a first layer and a backing structure (18). The first layer has a polishing surface and a backing surface (19). The first layer is formed of a soluble component in a polymer matrix (16). The polishing pad comprises a first layer and a backing structure (18). The first layer has a polishing surface and a backing surface (19). The first layer is formed of a soluble component in a polymer matrix (16). The soluble component provides a solid structure in the interior of the first layer, and comprises a material soluble in the slurry to form a void structure in the polishing surface. The backing structure comprises an adhesive layer fixed to the backing surface. The slurry contains abrasive particles and dispersive agent. An independent claim is included for polishing a substrate using the pad. |
