dc.description.abstract本研究開發一種新型的乾式混合造孔劑之技術用以製作高性能超細目鑽石砂輪,研究採用了砂輪的單批次生產過程,其優點是不使用樹酯液作為添加的黏合劑。由於沒有濕潤劑的使用,可以避免超細鑽石磨料、超細結合劑及造孔劑在混合過程中產生結塊,於大批量的生產可以實現整體砂輪混合的均一性,而將混合錯誤和人為因素造成的混合不均勻降到最低。此外研究中之低溫燒結可以有效地減少碳足跡,在較低的燒結溫度620℃下,砂輪擁有更高的孔隙率(~82%)且微觀結構呈現出均勻的大氣孔,這對晶圓表面的去除和研磨過程中可避免晶圓燒焦。研究以熱重-差示掃描量熱儀(TG-DSC)來測定超細結合劑的熱流和重量損失。利用光學非接觸式分析儀對超細結合劑粉末進行分析,以及設定砂輪的燒結溫度與升溫曲線。掃描電子顯微鏡(SEM)圖像顯示,燒結後孔隙結構沒有分層、特大連通孔和微結構損傷。原子力顯微鏡(AFM)、雷射掃描數位顯微鏡(LSCM)和掃描電子顯微鏡結果顯示,研磨後的矽(Si)表面粗糙度低至6nm,沒有深的刮痕,而且損傷層低於0.7μm。這項研究提供了一種新的方法為乾式超細鑽石砂輪製造技術,以製作出的新型砂輪用於矽晶圓研磨,實現以研磨方式來取代部分化學拋光(CMP)製程,並有效減少拋光時間。zh_TW
dc.description.abstractA novel dry process that prepared in mixing with a pore-forming agent employs a single batch process in production of grinding wheels with the advantage without using resin liquid as an additive binder. The agglomeration of a pore-forming agent can be avoided due to no dressing agent mixing with the superfine diamond abrasives and binders. Bulk mass production can still ensure to fulfill the excellent homogeneity in mixing cross the entire grinding wheel. Therefore, an uneven mixing caused by mixing errors and human factors can be minimized. The grinding wheel can reach an ultrahigh porosity (~82 %) at a lower sintering temperature of 620 °C. Low-temperature sintering can effectively reduce the carbon footprint. A thermogravimetric-differential scanning calorimeter (TG-DSC) was used to determine the thermal properties of superfine frits. Further characterization of ultrafine binders by an optical non-contact dilatometry is utilized to set-up a protocol sintering plan of grinding wheels. Microstructure from scanning electron microscope (SEM) measurement on grinding wheel presents a uniform large pore structure which offers a benefit to wafer surface removal and less scorching during grinding. Atomic force microscopy (AFM), laser scanning digital microscope (LSCM) and SEM results revealed that the ground silicon (Si) wafer had a low surface roughness (~ 6 nm), without deep scratches, and with a low damaged layer (~0.7 μm) respectively. The wear test on grinding wheels demonstrates it is very cost effective to use a dry processing wheel. This work provides a new method for grinding Si wafers with a new type of wheel being developed by a novel dry superfine diamond grinding technique in a manufacturing process. It is realized that the use of a dry grinding process can save part of chemical polishing process (CMP) and effectively reduces the polishing time.en_US
