发明名称 POLISHING PAD AND METHOD FOR MAKING THE SAME
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.
