  • Patent number: 10828745
    Abstract: A polishing pad is provided. The polishing pad, disposed on a polishing platen and suitable for a polishing process, includes a polishing layer, an adhesive layer and at least one adhesion-reducing interface layer. The adhesive layer is disposed between the polishing layer and the polishing platen. The at least one adhesion-reducing interface layer is disposed between the adhesive layer and the polishing layer and/or disposed between the adhesive layer and the polishing platen. An area of the at least one adhesion-reducing interface layer is smaller than an area of the adhesive layer.

  • Patent number: 10421173
    Abstract: A base layer, a polishing pad with a base layer and a polishing method are provided. The polishing pad includes a polishing layer and a base layer. The base layer, underlaid below the polishing layer, is a three-dimensional fabric. The three-dimensional fabric comprises a top woven layer, a bottom woven layer, and a supporting woven layer disposed between the top woven layer and the bottom woven layer. The top woven layer and the bottom woven layer are respectively woven by a plurality of first set of yarns and a plurality of second set of yarns. The supporting woven layer comprises a plurality of supporting yarns interconnecting the top woven layer and the bottom woven layer, so that a space exists between the top woven layer and the bottom woven layer.

  • Patent number: 9707662
    Abstract: A polishing pad having a detection window and a method of manufacturing the polishing pad are provided. A dummy detection window is pre-disposed in a mold. A polishing layer precursor is filled into the mold, and then a solidifying process is performed to form a polishing layer, wherein the polishing layer and the dummy detection window are separable completely. The polishing layer and the dummy detection window are separated from each other so as to form a detection opening in the polishing layer. The detection opening can alternatively be formed in a mold having a protrusion structure to replace the dummy detection window. A detection window precursor is filled into the detection opening, and then a solidifying process is performed to form a detection window.
