  • Patent number: 9022840
    Abstract: An abrasive tool including a CMP pad conditioner having a substrate including a first major surface, a second major surface opposite the first major surface, and a side surface extending between the first major surface and the second major, wherein a first layer of abrasive grains is attached to the first major surface and a second layer of abrasive grains is attached to the second major surface. The conditioner further includes a first sealing member extending in a peripheral direction along a portion of the side surface of the substrate.

  • Patent number: 8951099
    Abstract: A chemical mechanical polishing (CMP) conditioner includes a ceramic substrate having a major surface, and an abrasive coating overlying the major surface. The major surface can include micro-protrusions arranged in a curved pattern. Alternatively, the micro-protrusions can be arranged in an irregular pattern.

  • Patent number: 8905823
    Abstract: An abrasive tool for conditioning CMP pads includes abrasive grains coupled to a substrate through a metal bond and a coating, e.g., a fluorine-doped nanocomposite coating. The abrasive grains can be arranged in a self-avoiding random distribution. In one implementation, an abrasive tool includes a coated plate and a coated abrasive article that has two abrading surfaces. Other implementations related to a process for producing an abrasive tool that includes a coating at one or more of its surfaces. Also described are methods for dressing a CMP pad.

  • Publication number: 20120149287
    Abstract: A method of forming a chemical mechanical planarization (CMP) pad conditioner includes placing abrasive grains on a major surface of a substrate, forming a binding composition at an exterior surface of the abrasive grains, and depositing a bonding layer over the surface of the substrate and a portion of the abrasive grains to secure the abrasive grains to the major surface of the substrate.

  • Patent number: 7195549
    Abstract: A drum grinding wheel includes an elongated drum configured for coaxial engagement with a spindle of a grinding machine. An exterior surface of the drum extends parallel to a central axis, and a plurality of removable cutters are removably fastened to the exterior surface. Each of the cutters has a plurality of ribs disposed in spaced relation thereon, and abrasive grain is disposed on a grinding face of each of the ribs, such as by use of a metallic braze.
