Sufficient material removal rate. When the content of the basic compound is high, the viscosity of the polishing composition is greatly increased, so that ~, and then the subsequent polishing of the glass substrate on the glass substrate in the polishing composition, water is used as a raw material for dissolution and dispersion. Water preferably contains as few impurities as possible to avoid inhibiting the effects of other raw materials. In particular, it is preferably used to remove contaminated ions, ion exchange resins, and then contaminate the private, M, and M through a filter, < < this product through < pure or ultrapure water, or distilled water An emulsifier is included in the polishing composition. The oxidant is used as a polishing accelerator that accelerates the mechanical polishing of the silicon dioxide by oxidizing the surface of the glass substrate.

For example, emulsifiers May include hydrogen peroxide, ammonium persulfate, potassium chlorate, potassium perchlorate, sodium perchlorate, potassium periodate, sodium periodate, potassium bromate, and sodium bromide. Among these materials, peroxide & To greatly improve the mechanical grinding of silicon dioxide. One or more kinds of oxygen may be included in the grinding composition The content of the oxidant in the grinding composition is between 0.0005 and 10% (mass%), preferably between 0.01-8% (masS%), and most preferably between 0.005% and 5%. (mass%). When the oxidant content is less than 0.005% (inass0 / 0), because the oxidant is not enough to accelerate the mechanical grinding effect of silicon dioxide, it may not be sufficient without the 2188-6693-P 11 200530380 method. The material removal rate. When the oxidant content is high ^ iq% (simplified s%), the viscosity of the second grinding composition is greatly increased, so that the grinding composition tends to be compacted, and thus the roughness of the glass substrate after subsequent grinding is increased. Increase. According to actual needs, the grinding composition may further include a coupler called agei), a surfactant, a preservative, or the like. The grinding composition is made by mixing raw materials other than water with water. During the mixing process, it may be A blade-type stirrer or an ultrasonic disperser is used. The order of mixing raw materials other than water with water is not limited. The grinding composition according to the embodiment of the present invention is diluted with water or not added. When the grinding composition is When diluted with water, the dilution ratio (better volume ratio: More than 50 times, more preferably not much, and most preferably not more than 10 ° ° When the dilution rate exceeds 5G times, the content of the dioxide and the acid in the grinding composition after dilution may be insufficient, thus causing insufficient Material removal rate. The two-step process including the rough grinding step and the fine grinding step is studied as follows: First, in the rough grinding step, the glass substrate surface step: the strategy: by including the oxide decoration Grinding. Grinding. Next, grinding the glass substrate surface with the grinding composition according to the present invention. = In the step, the glass substrate is attached to a polishing head. This polishing head is continuously located on a turntable under a fixed pressure. The material is continuously supplied to the surface of the polishing pad. Therefore, it should be noted that the glass substrate adopts the polishing composition according to the present invention: grinding under H · honing procedure 'and then replaces-multi-stage polishing process 2l88-6693-p 12 200530380 sequence. The present invention has the following advantages. The polishing composition according to this embodiment includes an abrasive of silicon dioxide. Compared with the abrasive composition of abrasives containing hafnium oxide, this can reduce the surface roughness of the glass substrate after grinding. It is inferred that such a performance is due to the irregular shape of the main particles of hafnium oxide, and the dioxin is a spherical particle. Because the main shape is spherical, the dream dioxide is more suitable for polishing the surface of glass substrates than osmium oxide to reduce the surface roughness of the glass substrate after polishing. In addition, for glass substrate materials, dioxane has a lower reactivity compared to oxidized trim. For this reason, the stone dioxide adhered to the broken glass substrate can be easily removed by cleaning the glass substrate 'without sticking to the surface of the glass substrate by reacting with the material of the broken glass substrate. Therefore, the abrasive composition according to this embodiment has a characteristic that it can be easily removed from the abrasive surface. In addition, compared with oxygen, the dioxane has an anti-cutting effect in the grinding composition; the car has large dn cohesion and high dispersibility (please refer to the later examples and comparisons 4 and 5). Therefore, according to the research of this embodiment: a good dispersive adhesive. The chemical grinding effect of the test compounds in the grinding composition can accelerate the mechanical grinding of # _ and ^ + π using silicon dioxide. By such an alkalinization, the ability of the polishing composition to polish the surface of a glass substrate, γ, can be improved. Material # divide rate. It should be noted that when the test compound improves the material removal rate by activating the surface of the di-emulsified stone and engraving the surface of the glass-breaking substrate, it is not considered as the surface of the glass-breaking substrate. Make it brittle. Next, examples and comparative examples of the present invention will be described in detail below. In Example 1-29, the abrasive was mixed with basic compounds with water, and an oxidizing agent was further added later according to the general needs, thereby preparing a storage solution of the abrasive composition. In the ratio ㈣W t, a storage solution of the grinding composition is prepared by mixing the abrasive with water and adding an oxidant later according to actual needs. The types of abrasives, test compounds and oxidants used are shown in Table 1. Then, the ultra-pure water is used to dilute each storage solution according to Examples 1-29 and Comparative Example "5" so that its final volume is increased by 10 times compared to the initial volume, thereby preparing a grinding composition. According to the examples ... and comparative examples Each of the polishing compositions of "5" polished different glass substrate surfaces under the polishing conditions described below. The mass of each glass substrate was measured before and after grinding, and then the material removal rate was calculated by the following formula. Based on the obtained m core-receiving material transfer, each grinding composition M 疋 has four grades: ⑴ is very good; ⑺ is good; (3) is slightly worse; ⑷ is not good. In particular, when the grinding composition ^ is 骑, Riding Branch. . 5 micrometers per minute; when the material removal rate is lower than 0.05 "below 0.03 micrometers per minute, there are irregularities in the knife, and the flatness is good; when the lining is removed at 0.03 micrometers per minute When it is not less than 0 W / m / min, and it is slightly worse; when the material removal rate is less than 0, extremely poor. For the results of the feed setting, please refer to Table 03 and the rating will be shown in the table. The material removal rate is 2188-6693-P 200530380.
