  • Patent number: 11000935
    Abstract: The present invention relates to a polishing pad that minimizes the occurrence of defects and a process for preparing the same, Since the polishing pad comprises fine hollow particles having shells, the glass transition temperature (Tg) of which is adjusted, the hardness of the shells and the shape of micropores on the surface of a polishing layer are controlled. Since the content of Si in the polishing layer is adjusted, it is possible to prevent the surface damage of a semiconductor substrate caused by hard additives. As a result, the polishing pad can provide a high polishing rate while minimizing the occurrence of defects such as scratches on the surface of a semiconductor substrate during the CMP process.

  • Patent number: 10537897
    Abstract: A grinding machine includes a slight gyration module for driving a homogeneous container to undergo an X-axial motion and a Y-axial motion within ±1-3 mm distance, a homogeneous-stick rotation module for rotating a homogeneous stick in the homogeneous container so as to generate an eccentric motion between the homogeneous stick and the homogeneous container, and a homogeneous-stick vertical movement module for vertically moving the homogeneous stick with respect to the homogeneous container. When the homogeneous stick is lowered into the homogeneous container by the homogeneous-stick vertical movement module, an eccentric motion with a 1-3 mm radius of gyration can be activated between the homogeneous container and the homogeneous stick so as to carry out the grinding in a tiny slim space between the homogeneous container and the homogeneous stick; such that the grinding efficiency of the grinding machine can be substantially enhanced.
