    • 摘要: Single crystal sapphire has high mechanical and optical properties, which is widely used in optical electronics, communications, national defense and other fields. In it, in order to improve single crystal sapphire surface quality and shorten the processing time, the method of chemical mechanical polishing was adopted and a feasible and effective processing technology was obtained. The experimental results showed that the surface roughness value Ra is reduced from 220.05nm to 7.88nm after polishing for 1.5h with 6μm diamond abrasive;Then 3μm diamond abrasive is used for fine polishing sapphire wafer for 1.5h,a surface roughness,Ra=2.82 nm(measurement area(700×530)μm),can be achieved.The polishing technique can basically satisfy requirements of high efficiency and low damage for polishing sapphire substrate.%单晶蓝宝石具有高的机械和光学性能,已被广泛应用于光电子、通讯、国防等领域.以提高加工后单晶蓝宝石表面质量和缩短加工时间为最终目标,采用化学机械抛光的方法抛光蓝宝石,得到了一种可行有效的抛光单晶蓝宝石的加工工艺路线.试验结果表明,采用6μm金刚石磨料粗抛蓝宝石晶片1.5 h,表面粗糙度值由220.05 nm快速降到7.88 nm;然后采用3μm金刚石磨料精抛蓝宝石晶片3 h,可以获得Ra约为2.82 nm(测量区域700μm×530μm)的表面粗糙度值.此抛光工艺能满足蓝宝石衬底高效、低损伤的抛光要求.

    • 摘要: 随着化学机械研磨的持续进行,垫表面特征会发生变化,从而使其研磨能力大大降低.修整垫可改善表面轮廓,进而提高被加工晶片表面质量,而且可以减少表面缺陷,延长使用寿命.本文着重介绍固结磨料研磨垫常见修整技术,分为非自修整和自修整两种类型,非自修整法有高压水射流修整、超声波振动法修整、金刚石修整器修整.并重点阐述通过合理选用研磨液、添加成孔剂以及优化研抛工艺参数等措施来促进亲水性固结磨料研磨垫自修整.%The surface features of abrasive pad deform during chemical mechanical polishing and as a result the polishing ability of the pad is dramatically reduced.Pad conditioning improves the pad surface profile and consequently the wafer profile.In addition,it reduces defects on pad surface and prolongs its service life.The conditioning technologies of fixed-abrasive pad are introduced in this paper,which can be divided into two types,namely non-self-conditioning and self-conditioning.High pressure water jet,ultrasonic vibration and diamond dresser etc are non-self-conditioning methods.The methods of improving the self-conditioning of hydrophilic fixed polishing pad are emphasized.Choosing proper slurry,adding soluble and optimizing the lapping process parameters can benefit the self-conditioning process.

    • 摘要: 为探究金刚石磨料和酚醛树脂性能对砂轮磨削硬质合金的影响,首先选择三种不同金刚石磨料制作砂轮,通过磨削试验对金刚石进行优选,其次再通过磨削试验探究四种不同酚醛树脂与金刚石磨料的匹配性,以达到最佳的磨削效果.试验结果表明,金刚石3#强度大、热稳定性好、自锐性强,可以获得较好磨削效果,选择与之匹配的酚醛树脂结合剂A,砂轮的磨削比大、持续锋利性好,对大切深有较强适应性,在磨削硬质合金方面可以获得较好的效果和应用.%To study the influence of diamond abrasives and phenolic resins in grinding performances for ce-mented carbide, a series of grinding experiments for three wheels made with three different types of diamond abrasives were carried out, which lead to a preferred type for diamond abrasives. And then, the matching of the preferred diamond abrasive with four kinds of phenolic resins were researched through grinding experi-ments, in order to achieve great grinding effects. The results demonstrated that the grinding effects of dia-mond 3 # were best, because of its high strength, excellent thermostability, and good self-sharpening. Be-sides, phenolic resin bond code-named A had a good matching with diamond 3 #, and the wheel had great grinding performances in abrasion resistance, persistent sharpness, and deep grinding adaptation, which could be well applied to grinding cemented carbide materials.
    • 摘要: 人造金刚石磨料是在高温超高压条件下合成出来的,高压腔内压力、温度条件不完全一致,生长的金刚石不尽相同,因而其性能亦不相同。已有研究表明,金刚石磨粒的强度和破碎性能主要取决于其晶形及其规则程度、内部缺陷及杂质含量和分布形式等。

    • 摘要: 采用铜基螺旋槽研磨盘对6 H–SiC 单晶基片的 Si 面和 C 面进行了单面研磨加工,研究研磨压力、研磨盘转速和金刚石磨粒尺寸对 SiC 基片材料去除率和表面粗糙度的影响。结果表明,单晶 SiC 的 C 面和 Si 面具有明显的差异性,C 面更易加工,其材料去除率比 Si 面大。研磨压力是影响材料去除率和表面粗糙度的主要原因,研磨压力越大,材料去除率越高,但同时表面粗糙度变大,较大的研磨压力会导致划痕的产生。在达到最佳表面粗糙度时,C 面加工所需的转速比 Si 面大。磨粒团聚会严重影响加工表面质量,采用粒度尺寸3μm 的金刚石磨料比采用粒度尺寸1μm 的金刚石效果好,经粒度尺寸3μm 的金刚石磨料研磨加工5 min 后,Si 面从原始粗糙度 Ra 130 nm 下降到 Ra 5.20 nm,C 面下降到 Ra 5.49 nm,表面质量较好。%The Si face and C face of 6 H–SiC single crystal wafer were lapped by using the copper based lapping pad with spiral grooves and the effects of lapping pressure pad speed and abrasive size on the material removal rate and the surface roughness of SiC were studied The results show that the lapping characteristics of C face and Si face have obvious difference The C face is easier to lap and the material removal rate of C face is larger than that of the Si face The lapping pressure is a key parameter that influences material removal rate and surface roughness The higher the lapping pressure is the larger the material removal rate is but the surface roughness R a increases as well High lapping pressure can generate scratches on SiC surface To achieve a better surface roughness the lapping speed of the C face should be faster than that of the Si face It's also found that agglomeration of the diamond abrasives will seriously affect the quality of the lapped surface Therefore the lapping quality of SiC surface with 3 μm diamond abrasive is better than that with 1 μm diamond abrasive After lapping for 5 min with 3 μm diamond abrasive the surface roughness of Si face decreases from original R a 130 nm to R a 5 20 nm and the surface roughness of the C face decreases to R a 5 49 nm.
