    Abstract: The work of replacing a polishing pad is easily performed, and thermal damage is prevented from occurring in a polishing table. A polishing apparatus 100 includes a polishing table 110 having an attachment surface 110a to which a polishing pad 108 used to polish a substrate 102 is attached. The polishing apparatus 100 also includes a silicone layer 111 provided on the attachment surface 110a of the polishing table 110 and interposed between the polishing table 110 and the polishing pad 108. By interposing the silicone layer 111, it is possible to easily detach and attach the polishing pad 108. In addition, since a heat treatment for coating the silicone layer 111 on the polishing table 110 is performed at a relatively low temperature, it is possible to prevent thermal damage from occurring in the polishing table 110 due to the heat treatment.

In accordance with some embodiments, a selected side surface of the tool is placed in contacting engagement against an upper reverse sharpening guide surface that faces an abrasive surface extending along a first plane. The upper reverse sharpening guide surface is aligned along a second plane that intersects the first plane at an acute angle. A tool cutting edge contactingly engages a non-abrasive support surface disposed between the upper reverse sharpening guide surface and the abrasive surface to establish a plunge depth of the tool prior to contact with the abrasive surface. The tool is thereafter moved away from the upper reverse sharpening guide in a lateral direction across the abrasive surface while nominally maintaining the tool at the acute angle to sharpen the cutting edge in a trailing cutting edge orientation.

  • Publication number: 20120276825
    Abstract: This disclosure is directed to a chemical mechanical polisher and a polishing pad component thereof. The chemical mechanical polisher comprises a polishing platen having a flat surface, and the polishing platen comprises: an electromagnet disposed under the flat surface and configured to fix a polishing pad base on the flat surface; and a switch configured to control the power-on and power-off of the electromagnet. The polishing pad component comprises a polishing pad base, and the polishing pad base is formed of a ferromagnetic material. The chemical mechanical polisher of this disclosure and the polishing pad component thereof can make polishing pad replacement easy, and can also save polishing pads and thus reduce the consumable cost of the chemical mechanical polishing.

  • Patent number: 8142262
    Abstract: The invention relates to a grinding device, comprising a mounting body which is detachably connected to a grinding element, said detachable connection being designed such that the mounting body has a first adhering arrangement and the grinding element has a second adhering element and the adhering elements correspond in the manner of a Velcro fastener. The aim of the invention is to improve the quality and efficiency of the detachable connection for exchange of the grinding element of the claimed grinding device. Said aim is achieved, wherein the first adhering element (1) and the second adhering element (2) comprise a number of projections (3) each with a cross-sectional widening in the direction of the free end (7) of the projection (3).

  • Publication number: 20120071073
    Abstract: A structure for a backing plate of an abrasive disk is disclosed. The structure includes layers of abrasive resin interspersed with layers of reinforcing fiberglass. The layers are generally disk shaped and cover certain radial intervals of the entire backing plate between the inner diameter and the outer diameter. For example, a radial stress profile plotting the stress along a radial line from inner to outer diameter can be determined. The amount and radial positioning of reinforcing layers (e.g., reinforcing fiberglass) may then be determined. An appropriate amount of reinforcing layers may then be placed within the radial intervals that experience the highest stress.

  • Publication number: 20120040590
    Abstract: In a non-conventional lap tool, i.e., not a stiff tool nor a conformable tool, and related method for grinding/polishing a substrate surface, includes a rigid base plate and attached work surface to define a cavity containing a non-Newtonian fluid. The non-Newtonian fluid behaves as a solid when the work surface is subjected to high shear stress, i.e., rapid tool stroke, yet behaves like a liquid when the tool is moved around the substrate surface when the shear stress of the work surface is low. A diaphragm can be used to further define the cavity and to seal within the non-Newtonian fluid therein.

    Abstract: A device for chamfering and sanding is disclosed. The device comprises a cylindrical body containing a hollow cone lined with sandpaper attached to the surface of the cone with adhesive. Two corners of the sandpaper are inserted respectively into two slots contained in the sidewall of the cone to further hold the sandpaper in place. The device comprises a shaft attached to the bottom of the device for clutching by a drill press or a three jaw chuck. As the device rotates, objects that require bevelling or sanding are inserted into the cone and pressed against the sandpaper. A sandpaper sleeve is attached to the outer surface of the cylindrical body that may be used for sanding and smoothing.
