Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a polishing process, and more particularly to a polishing abrasive used in a polishing process and a method of manufacturing the same. [Prior Art] At present, precision machining technology is more and more widely used, and the polishing process is a frequently used part of the technology, and plays an important role in precision machining technology. It can be widely used in computer heads, semiconductor wafers, and opticals. Surface polishing of glass devices and ceramics to achieve high precision, low roughness surfaces. In many polishing processes, chemical mechanical polishing (CMP) is the most common application, and related technologies are developing rapidly. Su Jianxiu and others in the "Semiconductor Technology", 2003 'V28 (1G) '27_32, "Ultra-large-scale integrated circuit manufacturing cut #chemical mechanical polishing technology analysis" article details the structure and principle of traditional chemical mechanical polishing system. Referring to the first figure, the system mainly comprises a rotary holder 1, a table 2 carrying a polishing pad 4, and a conveying device 3 for polishing the slurry 9. The holder i includes a rotating shaft 5 and a clamping head 6 connected thereto, and the clamping head 6 is used for holding the workpiece 7 to be polished so as to be between the clamping head 6 and the polishing pad 4, and the clamping head 6 The surface of the workpiece 7 has a lunar membrane 8. In the chemical mechanical polishing, the rotary holder 1 presses the workpiece 7 on the polishing pad 4 with a certain pressure, and the polishing slurry 9 composed of the submicron or nano abrasive grains and the chemical solution is on the workpiece 7 and the polishing pad 4. Flowing between and generating a chemical reaction, the chemical reactant formed on the surface of the workpiece 7 is removed by mechanical action of the abrasive grains, that is, ultra-precision surface processing is realized in the process of alternating chemical film formation and mechanical film removal. Therefore, in order to achieve high efficiency and high quality polishing effect, the chemical action process must be well matched with the mechanical action process. However, there are many factors affecting the chemical action and the mechanical action. 5 1325009 It is necessary to consider various variables in the CMP system, such as acting on the workpiece. Polishing pressure, relative speed of the polishing pad to the holder ' polishing zone temperature, slurry viscosity, pH, pad material, and abrasive size, concentration and hardness. Under normal circumstances, when the size of the abrasive increases, the polishing rate increases, and the scratches on the surface of the cymbal sheet also increase. However, if the abrasive size is too small, it tends to agglomerate into a mass, which will still increase the surface scratch of the stone slab; when the hardness of the abrasive increases, the polishing Increasing the rate also increases the scratch on the surface of the bract and reduces the quality of the surface finish. Therefore, to obtain better surface finish quality and reduce scratches, choose the appropriate abrasive size and hardness, or use other properties to eliminate these deficiencies. The sintered ceramic particles 18 are dispersed in the adhesive layer, and can be large in size, causing a large scratch on the surface of the workpiece.

The 3 〇〇 particle ls includes sintered squeezing particles 1 §, and the average particle diameter is in the range of ~(5) micrometers, wherein the granules are known as 'dioxotomy, yttrium oxide or a combination thereof. This special deficiency. 'Can eliminate the agglomeration phenomenon of the particles 18, but its particle size is better than the other 'Wei touch: the grade is paid in the anti-wear performance is low. 2〇〇1 July 25th, the mainland China No. 6 patent grade polishing liquid and Its preparation method. 5 Heinami grade polishing liquid from nano-grade diamond powder, please disclose a kind of nano-powder 'non-ionic type 6 1325009 powder stabilizer, antistatic agent, detergent and Q white light white oil or naphtha composition, its preparation The method comprises the following steps: mechanically grinding the nano diamond into a powder, drying; adding a dispersion stabilizer, heating and mixing to wet the powder; adding white oil or naphtha, an antistatic agent, a detergent, and an appropriate pH adjusting agent, And constantly stirring 'dispersion of the mixture into a suspension.
