Abstract:
PURPOSE: A method for manufacturing a polishing pad with nano diamonds, a polishing pad manufactured thereby, and a polishing method using the polishing pad are provided to reduce the amount of polishing slurry because polishing particles and nano diamonds are mixed with polyurethane resin. CONSTITUTION: A method for manufacturing a polishing pad with nano diamonds is as follows. Polishing particles and nano diamonds are uniformly scattered and mixed with polyurethane resin. The mixed materials are injected into a mold and are molded in a specific shape. The molded products are dried in a drying machine. A polishing pad is manufactured by thinly slicing the dried products. The polishing surface of the polishing pad is uniformly trimmed by rapidly rotating a buff. The polishing pad is cut with a specific size.
Abstract:
PURPOSE: A polishing slurry is provided to minimally reduce surface roughness and to improve planarity and to reduce surface roughness of a wafer and plate in polishing. CONSTITUTION: A method for manufacturing a surface abrasive comprises a step of mixing 60~72 wt% colloidal silica(SiO2), 0.5~3 wt% diamond with nano diameter, and 27.5~37 wt% ethylene glycol. A polishing method using a surface abrasive including nanodiamond comprises the steps of: positioning object(S) on a polishing platen(10) and a polishing pad(15); and providing the abrasive on the polishing platen and the polishing pad, an rotating the polishing platen and the polishing pad to polish the object.

Abstract:
PURPOSE: A method of manufacturing a diamond wire for processing semiconductor materials and a diamond wire manufactured by the same are provided to minimize the contamination of materials due to slurry by employing a diamond wire in which diamond abrasive particles used in multi-wire saw cutting are attached to a wire. CONSTITUTION: A method of manufacturing a diamond wire for processing semiconductor materials comprises steps of: feeding a wire(S1), coating a UV hardener on the surface of a wire(S2), attaching diamond particles to the surface of the wire in which the UV hardener is spread(S3), and hardening the UV hardener(S5). The wire feed step includes a cleaning process for removing organic materials or other foreign substances from the surface of a wire, a heat treatment process for heat-treating the wire at 100°C-130°C, and a surface activation process for passing the wire through diluted acid solution of 5%-20%.
