    摘要: This disclosure relates to a polishing pad for chemical mechanical polishing, having a shape where 3 or more semi-oval or semicircular curves that connect 2 valleys neighboring on the plane are connected, and including 2 or more modified patterns that are formed to a determined thickness on the polishing pad, wherein a peak of one modified pattern and a valley of another modified pattern neighboring thereto are sequentially located on the same line. The polishing pad may uniformly disperse slurry over the whole area during a polishing process to provide improved polishing uniformity, and appropriately control residence time of the slurry to increase polishing rate.

    摘要: The present invention provides a method for producing a porous sheet, including the steps of a) producing a polymer resin sheet containing an object to be processed by supercritical fluid extraction which is dissolved in supercritical fluid; and b) injecting the supercritical fluid into the polymer resin sheet to extract the object to be processed by supercritical fluid extraction that is contained in the polymer resin sheet, thereby forming pores in the polymer resin sheet, and a porous sheet produced by the same.
