Abstract: A grinding tool includes a substrate having a surface provided with a plurality of openings, and a plurality of grinding studs. Each of the grinding studs includes a stud portion and an abrasive particle attached to each other, the stud portions being respectively attached into the openings, and the abrasive particles protruding outward from the surface, each of the abrasive particles having a pattern cut across a tip thereof to define multiple apexes adjacent to one another.

Abstract: A grinding tool includes a substrate and a plurality of abrasive particles. The substrate has a first and a second surface and a plurality of holes, each of the holes extending through the substrate and respectively having a first and a second opening on the first and second surface, the second opening being larger than the first opening. The abrasive particles are respectively disposed in the holes and attached to the substrate via a plurality of adhesive portions, each of the abrasive particles having a tip protruding outward from the first surface and a remaining part covered with one of the adhesive portions inside the corresponding hole, wherein the first openings of the holes are smaller than the abrasive particles, and the abrasive particles are respectively retained in the holes. Moreover, embodiments described herein include a method of fabricating a grinding tool.

Abstract: A grinding tool includes a rigid support body and a carrier substrate. The carrier substrate is attached to the support body, and is supported by the support body. Two opposing surfaces of the carrier substrate respectively define a working surface and a non-working surface. A plurality of first abrasive particles are affixed on the working surface, and a plurality of second abrasive particles are affixed on the non-working surface. The first abrasive particles have a first average size, and the second abrasive particles have a second average size smaller than the first average size. The carrier substrate is attached to the support body at the non-working surface. Moreover, a method of manufacturing the grinding tool is described herein.

Abstract: The present invention relates to a chemical mechanical polishing conditioner with high performance, comprising a substrate; a binding layer disposed on the substrate; and a plurality of abrasive particles fixed directly on the substrate by the binding layer, or each abrasive particle disposed on a metal fixing seat and the substrate have a plurality of blind holes and a plurality of through holes, so that the metal fixing seats are installed into the blind holes or the through holes, and the metal fixing seat fixed on the substrate by the binding layer; wherein the abrasive particles are treated by a surface processing treatment to make the abrasive particles have specific cutting edge angles, crystal structures, tip heights, or tip orientations. Therefore, the present invention can control the profile of each abrasive particle to accomplish the best polishing performance.

Abstract: The present invention relates to a chemical mechanical polishing conditioner with optimal abrasive exposing rate, comprising a substrate; a bonding layer disposed on the substrate; and a plurality of abrasive particles placed on the bonding layer, and the abrasive particles are placed on the substrate by the bonding layer; wherein each abrasive particle has an abrasive exposing rate which is ¼ to ¾ of particle sizes of the abrasive particles and is measured by a height measuring device. Therefore, the chemical mechanical polishing conditioner with optimal abrasive exposing rate of the present invention can control the exposing rate of the abrasive particles to improve the cut rate of the conditioner.
