    摘要: The present invention relates to a method for manufacturing a polishing pad. The method of the invention includes the steps of forming a polishing layer from a polyurethane solution has a solid content more than about 90 wt % and drying the polyurethane solution at a temperature from about 130° C. to about 170° C. The invention also provides a polishing pad manufactured by the method mentioned above. The defect of scraping the surface of the substrate to be polished due to polishing particles remaining is avoided when applying the polishing pad according to the invention, and the flatness of the substrate to be polished is raised and the defective rate is eliminated also.

    摘要: The present invention relates to a polishing pad and method for making the same. In the invention, a liquid-state polymer material is directly formed on the surface of a base material, and then the liquid-state polymer material is solidified to form a flat grinding layer. Whereby, the polishing pad has high unity and flatness. The grinding layer has attenuated structures and a plurality of holes, thus increasing the storage ability of polishing particles distributed in a polishing liquid. In addition, the polishing pad has high compression ratio, so the polishing pad can compactly contact a polishing workpiece, and will not scratch the surface of the polishing workpiece scratched. Therefore, the polishing effect and quality will be improved.

    摘要: The invention relates to a polishing pad having hollow fibers and a method for making the same. The polishing pad comprises a body and a plurality of hollow fibers. The body has a polishing surface. The hollow fibers are located within the body and have an opening on the polishing surface, wherein the hollow area of the section of each hollow fiber is larger than the sectional area of polishing particles in a polishing slurry. Therefore, the polishing slurry and polishing particles achieve a thorough circulation on the polishing pad via the hollow fibers.

    摘要: The present invention relates to a polishing pad having a surface texture. The surface texture is disposed on the polishing surface of the polishing pad. The surface texture comprises at least one first groove, at least one second groove, and a plurality of holes. The second groove extends from a central portion of the polishing pad to the edge of the polishing pad, and the first groove(s) is intersected with the second groove(s) to form a plurality of intersection points. The holes are disposed at the intersection points, and the depth of the holes is larger than that of the first groove. Thus, the second groove(s) enables impurities suspended in the polishing slurry to be quickly removed from the polishing pad, and the holes can store the polishing slurry to delay the polishing particles in the polishing slurry from departing from the polishing pad.

    摘要: The present invention relates to a sheet for mounting a polishing workpiece. The sheet comprises a substrate, a surface layer and a slightly rough layer. The substrate has a surface. The surface layer is located on the surface of the substrate, with no hole structure existing in the interior thereof, and has a surface. The slightly rough layer is located on the surface of the surface layer to carry and mount the polishing workpiece, with no hole structure existing in the interior thereof. Accordingly, when the polishing workpiece contacts the slightly rough layer, the air therebetween is easily vented out via the slightly rough layer, without the phenomenon of air wrapping, which increases the adsorption force between the polishing workpiece and the sheet.
