    摘要: A polishing pad includes a body having a polymer layer and a polishing layer. The polymer layer has opposite first and second faces. The polymer layer includes a plurality of first ultrafine fibers and a polymer bonding the first ultrafine fibers together. The polishing layer is formed on the first face of the polymer layer. The polishing layer includes a plurality of second ultrafine fibers and is free of the polymer. The first and second ultrafine fibers are identical to each other. The second ultrafine fibers have a first concentration of ultrafine fibers by volume higher than 80% a total volume of the polishing layer. The first ultrafine fibers of the polymer layer have a second concentration of ultrafine fibers by volume to a total volume of the polymer layer. The first concentration is higher than the second concentration.

    摘要: The present invention relates to a sheet for mounting a polishing workpiece. The sheet comprises a substrate and a surface 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 and a slightly rough layer. 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.

    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: A method is provided for making a polishing pad. In the method, ultrafine fiber-generating fibers are made into a non-woven fabric with two sides. At least one of the sides of the non-woven fabric is made a dense layer. The non-woven fabric is coated with a polymer. Because of the dense layer, the polymer cannot penetrate the non-woven fabric. The ultrafine fiber-generating fibers are converted to ultrafine fibers. Since the dense layer prevents the polymer from penetrating the ultrafine fiber-generating fibers, the ultrafine fibers remain a high concentration of fiber. The ultrafine fibers are transformed into nap. Therefore, the polishing pad is made with a polishing layer that includes the nap. The concentration of fiber of the polishing layer is higher than 80%.
