| 20110005143 | POLISHING OIL SLURRY FOR POLISHING HARD CRYSTAL SUBSTRATE - A hard crystal substrate such as a GaN substrate or a SiC substrate is polished by using polishing oil slurry having abrading particles of artificial diamond clusters dispersed in a dispersant. The artificial diamond clusters include approximately spherical agglomerate particles with average particle size D50 of 20 nm or more and 50 nm or less, having primary particles with particle diameters of 2 nm or more and 10 nm or less. A rough polishing process is carried out first such that an average surface roughness of 0.5 nm or more and 1 nm or less is obtained, followed by a finishing process such that the average surface roughness of said surface becomes 0.2 nm or less. | 01-13-2011 |
| 20090094901 | CMP Polishing Liquid and Polishing Method - A CMP polishing liquid being capable of using in a chemical mechanical polishing comprising of: a first chemical mechanical polishing step of polishing a conductive substance layer of a substrate having an interlayer insulation film containing convex and concave regions on a surface thereof, a barrier layer coating along the surface of the interlayer insulation film, and the conductive substance layer coating the barrier layer while filling the concave regions, and thus exposing the barrier layer in the convex regions; and a second chemical mechanical polishing step of exposing the interlayer insulation film in the convex regions by polishing the barrier layer exposed in the first chemical mechanical polishing step; characterized in that a difference (B)−(A) is 650 {acute over (Å)} or less,

| 20100170161 | METHOD FOR TREATING SPENT ABRASIVE SLURRY - The present invention relates to a method and a system for treating spent abrasive slurry obtained from a process for cutting a body of a substrate material into wafer-like slices, said slurry comprising a lubricant fluid, unspent abrasive particles and fines. | 07-08-2010 |
| 20100064593 | SLURRIES CONTAINING ABRASIVE GRAINS HAVING A UNIQUE MORPHOLOGY - A slurry containing a plurality of monocrystalline diamond particles, wherein the average surface roughness of said particles is less than about 0.95; a major vehicle selected from the group of water-based vehicles, glycol-based vehicles, oil-based vehicles or hydrocarbon-based vehicles and combinations thereof; and one or more optional additives. | 03-18-2010 |

| 20090139148 | SUPERABRASIVE GRAIN SETTING METHOD - In a superabrasive grain setting method, a two-dimensionally developed coordinate preparation step is taken, wherein a non-cylindrical area of a mounting surface where a tangential line to the mounting surface in a plane including the axis of the manufacturing mold crosses with the axis of a manufacturing mold is developed into a circular-arc belt-like surface, and a plurality of mounting points are set on the circular-arc belt-like surface in a grid pattern in dependence on mounting positions for superabrasive grains. Then, a rectification step is taken, wherein the grid pattern of the mounting points is rectified in predetermined angular ranges so that the mounting points do not make consecutive point lines in the circumferential direction of the circular-arc belt-like surface. A mounting step is thereafter taken of mounting the superabrasive grains on the mounting surface of the manufacturing mold based on the grid pattern rectified at the rectification step. | 06-04-2009 |
| 20100251623 | METHOD OF ASSEMBLING INNER DIAMETER GRINDING TOOL - A tool for grinding an inner diameter even when holders having grindstones are axially connected. A gap enclosed by the inner peripheral surface of a divided tool holder, a draw bar and O-rings is formed in a state in which the draw bar is inserted into a tool holder in which a plurality of divided tool holders are connected in series. A filler is filled into the gap to fix a support bush to the divided tool holder. An adjustment screw of each arm held circumferentially away from each other on the divided tool holder is turned to adjust a distance between a pin and the arm, and the radial projecting amount of each of grindstones is adjusted. The projecting amount is adjusted such that the plurality of grindstones rotate along the same rotational trajectory and the center of the rotational trajectory corresponds to the axis of the draw bar. | 10-07-2010 |
