Description
下文是關於形成研磨物件且特定言之，經結合之研磨物件之方法。 The following is a method of forming an abrasive article and, in particular, a combined abrasive article.
上世紀已研發多種研磨工具以用於不同工業以大體實現自工件移除物質，包含例如鋸割、鑽孔、拋光、清洗、雕刻以及研磨。在電子裝置之製造中，具有多個電路(諸如IC及LSI)之半導體晶圓之背面經研磨機械研磨達到預定厚度，之後分成個別晶片。為了有效研磨半導體晶圓之背面，通常使用配備有粗糙研磨單元及精整研磨單元之研磨機械。通常，用於進行粗糙研磨過程之物件為經結合之研磨體或研磨石，其是藉由將具有相對較大尺寸之鑽石研磨顆粒與玻璃化結合或金屬結合材料結合在一起而獲得。典型地使用具有鑽石研磨顆粒之樹脂結合研磨石完成研磨操作，所述鑽石研磨顆粒含於樹脂結合劑中且中值粒徑為2微米或大於2微米。較小尺寸之鑽石通常無法用於樹脂結合之物件中。 A variety of abrasive tools have been developed in the last century for use in different industries to substantially remove material from the workpiece, including, for example, sawing, drilling, polishing, cleaning, engraving, and grinding. In the manufacture of an electronic device, the back surface of a semiconductor wafer having a plurality of circuits such as an IC and an LSI is mechanically ground to a predetermined thickness by grinding, and then divided into individual wafers. In order to effectively polish the back surface of the semiconductor wafer, a grinding machine equipped with a rough grinding unit and a finishing grinding unit is generally used. Typically, the article used to carry out the rough grinding process is a bonded abrasive body or abrasive stone obtained by combining diamond abrasive particles of relatively large size with a vitrified bond or metal bond material. The grinding operation is typically accomplished using a resin with diamond abrasive particles in combination with a grinding stone contained in a resin binder and having a median particle size of 2 microns or greater. Smaller sizes of diamonds are often not used in resin bonded articles.
在一些情況下，無機結合劑之含量降低且孔隙度之量提高，認為這樣會降低玻璃化研磨石之表面的磨光或阻 塞、研磨結構之剝落、研磨石之不良打磨能力以及其他缺陷。通常，藉由在形成期間使用發泡劑來獲得高孔隙度研磨石體，所述發泡劑產生氣泡且因此在最終形成之研磨產物中產生孔隙度。 In some cases, the content of the inorganic binder decreases and the amount of porosity increases, which is believed to reduce the polishing or resistance of the surface of the vitrified grinding stone. Peeling, peeling of the abrasive structure, poor grinding ability of the grinding stone, and other defects. Typically, high porosity abrasive stone bodies are obtained by using a blowing agent during formation which produces bubbles and thus creates porosity in the final formed abrasive product.

形成兩種樣品以用於比較性測試。第一樣品CS1表示習知樣品，其由包含4.8重量%鑽石研磨粒子、89.4重量%預先合金化青銅(銅/錫比率為1)金屬結合材料以及5.8重量%具有約125微米之平均粒徑的石墨填充劑材料之混合物形成。將樣品CS1模型化成生坯，在約375℃至約700℃之溫度及約0.5噸/平方吋至4噸/平方吋之壓力下熱壓以形成經結合之研磨體，其具有約5體積%研磨粒子、20體積%石墨填充劑材料及約75體積%青銅結合材料。 Two samples were formed for comparative testing. The first sample CS1 represents a conventional sample comprising a metal binding material comprising 4.8% by weight of diamond abrasive particles, 89.4% by weight of pre-alloyed bronze (copper/tin ratio of 1) and 5.8% by weight having an average particle diameter of about 125 μm. A mixture of graphite filler materials is formed. Sample CS1 is modeled into a green body, hot pressed at a temperature of from about 375 ° C to about 700 ° C and a pressure of from about 0.5 ton / square inch to 4 tons / square inch to form a bonded abrasive body having about 5% by volume The particles were ground, 20% by volume of the graphite filler material, and about 75% by volume of the bronze bonding material.
第二樣品S2表示實施例之樣品，且是由包含19.5重量%鑽石研磨粒子、75.6重量%預先合金化青銅(銅/錫比率為1)金屬結合材料以及4.8重量%填充劑摻合物之混合物形成，所述填充劑摻合物包含2.4重量%具有約15微米之平均粒徑的石墨精細填充劑粒子及2.4重量%具有約125微米之平均粒徑的石墨粗糙填充劑粒子。使用與用於形成樣品CS1基本上相同之方法使樣品S2形成為經結合之研磨體。樣品S2具有19體積%鑽石研磨粒子、20體積%石墨填充劑摻合物以及約51體積%青銅結合材料，所述石墨填充劑摻合物包含10體積%精細填充劑粒子及10體積%粗糙填充劑粒子。 The second sample S2 represents a sample of the examples and is a mixture comprising a 19.5 wt% diamond abrasive particle, a 75.6% by weight prealloyed bronze (copper/tin ratio of 1) metal bond material, and a 4.8% by weight filler blend. Forming, the filler blend comprises 2.4% by weight of graphite fine filler particles having an average particle size of about 15 microns and 2.4% by weight of graphite coarse filler particles having an average particle size of about 125 microns. Sample S2 was formed into a bonded abrasive body using substantially the same method as used to form sample CS1. Sample S2 had 19% by volume diamond abrasive particles, 20% by volume graphite filler blend, and about 51% by volume bronze binder material, which contained 10% by volume of fine filler particles and 10% by volume of coarse filler Agent particles.
根據以下條件將樣品CS1及樣品S2用於c-平面 藍寶石基材之背磨操作。 Sample CS1 and sample S2 were used for c-plane according to the following conditions Back grinding operation of sapphire substrate.
圖1包含經結合之研磨體之累積滾輪磨損(以微米計)與自工件移除之累積材料(以微米計)相比較之圖。如所說明，與樣品CS1相比，對於移除更大範圍之累積材料樣品S2顯示顯著較低之滾輪磨損。亦即，與樣品S2相比，樣品CS1顯示顯著較少之總材料移除量，且對於限定之材料移除量亦顯著更大之磨損。 Figure 1 contains a graph of cumulative roller wear (in microns) of the combined abrasive body compared to cumulative material removed in the workpiece (in microns). As illustrated, significantly lower roll wear was shown for the removal of a larger range of cumulative material samples S2 than sample CS1. That is, sample CS1 showed significantly less total material removal compared to sample S2, and significantly greater wear for defined material removal.
圖2包含最大功率百分比對背磨操作時間之圖。如圖2中說明，樣品CS2之最大使用功率百分比顯示規則尖峰，表明在背磨操作期間發生研磨效率低且對經結合之研磨體施加較大力之狀態。相比之下，樣品S2在背磨操作期間顯示無顯著之定位尖峰，且因此表明與樣品CS1相比，在經結合之研磨體之整個使用期間研磨顯著更均勻且有效。 Figure 2 contains a plot of maximum power percentage versus back grinding operation time. As illustrated in Figure 2, the maximum used power percentage of sample CS2 shows a regular spike indicating a low efficiency of grinding during the backgrinding operation and a state of exerting a large force on the bonded abrasive body. In contrast, sample S2 showed no significant positioning spikes during the backgrinding operation, and thus indicates that the grinding is significantly more uniform and effective throughout the use of the bonded abrasive body compared to sample CS1.
