平面固结磨料研磨中研磨盘图案与沟槽设计的研究综述

引言

平面固结磨料研磨是一种常用于硅片、精密陶瓷、金属零件和蓝宝石晶片等材料表面加工的技术，其特点是在研磨工具（研磨盘或抛光垫）上固着磨粒进行材料去除 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。与传统游离磨料的研磨方式相比，固结磨料研磨具有加工效率高、过程稳定、易于控制等优点 (Speed ratio optimization for ceramic lapping with fixed diamond pellets | The International Journal of Advanced Manufacturing Technology) 。研磨盘表面的几何图案（如沟槽或磨料块排列）是影响研磨性能的关键因素之一。早在20世纪20年代就有人提出，通过减少研磨工具的有效接触面积来降低磨削区域温度和磨损 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) ，这奠定了在研磨工具上进行图案化设计的思想基础。实践证明，在研磨盘表面引入特殊设计的图案和沟槽可以显著改善研磨液流动、热量散逸以及磨粒受力状态，从而提升材料去除速率和表面质量 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。例如，在化学机械平面化（CMP）领域，已观察到不同沟槽图案的研磨垫在摩擦特性和材料去除率方面表现出明显差异 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。近年来，随着半导体晶圆尺寸增大和加工精度要求提高，如何通过优化研磨盘表面的图案与沟槽设计来进一步提高平坦化效率和均匀性，成为学术界和工业界关注的热点 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。

本文拟对平面固结磨料研磨中研磨盘图案与沟槽设计的研究进展进行全面综述。首先，我们将归纳研磨盘表面常见的图案与沟槽类型及其结构特征。接着，分析这些图案与沟槽对研磨过程关键性能（如磨削效率、磨粒分布、表面质量、热管理和力学响应等）的影响机制，总结相关实验研究结果与数值模拟发现。随后，我们对比不同材料（硅片、陶瓷、金属、蓝宝石）在采用不同图案研磨盘加工时的表现差异。最后，讨论当前研究的不足之处，并提出未来在研磨盘图案设计与优化方面可能的研究方向。

研磨盘图案与沟槽的类型与结构

研磨盘的图案与沟槽形式多种多样，按照结构形式大致可分为整体沟槽型和离散磨料块型两大类。

综上，研磨盘图案设计可以概括为通过改变研磨表面的接触几何来调控研磨过程。无论是整体沟槽还是离散磨料块，其共同目标是在宏观上改善研磨液流动和磨屑排出，在微观上优化磨粒接触分布和受力，从而实现更高效、更均匀且更低损伤的加工效果 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。下文将详细讨论不同图案和沟槽设计如何影响研磨的各项关键性能。

图案与沟槽对研磨性能的影响

研磨盘表面的图案/沟槽会通过多种途径影响研磨过程的性能，包括材料去除效率、磨粒和磨屑分布、工件表面质量以及研磨区域的热力学状态等。大量研究和实验已经揭示了其中的作用机理和规律，以下将分主题进行综述。

对材料去除率和均匀性的影响

研磨盘图案直接决定了工件表面材料去除的分布特征和速率。有效接触面积是一个关键因素：图案引入沟槽会减少同时参与切削的磨料总接触面积，但提高单位面积压力和改善磨削液输送，这常带来材料去除率（MRR）的变化 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。一般而言，适当的沟槽可以提升材料去除速率和改善去除均匀性，但若沟槽过多导致有效磨削面积过小，也可能降低瞬时总去除量 (Effect of concentric slanted pad groove patterns on slurry flow during ...) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。例如，在CMP领域的一项研究中，对具有不同沟槽几何的抛光垫进行比较，发现加宽沟槽且减小沟槽间距（即较宽槽、槽距紧密的网格图案）能加快磨液更新、缩短磨粒滞留时间，从而提高磨削刃口与工件的有效摩擦，显著提高材料去除率并降低片内不均匀性 (Effect of pad groove geometry on material removal characteristics in chemical mechanical polishing | International Journal of Precision Engineering and Manufacturing) (Effect of pad groove geometry on material removal characteristics in chemical mechanical polishing | International Journal of Precision Engineering and Manufacturing) 。该研究测得此类沟槽设计下抛光垫的动态摩擦系数（COF）有所升高，表明磨粒与工件的机械作用增强，去除速率上升且全局平坦化更均匀 (Effect of pad groove geometry on material removal characteristics in chemical mechanical polishing | International Journal of Precision Engineering and Manufacturing) 。

从磨料轨迹分布角度来看，研磨盘图案影响磨粒在工件表面的覆盖均匀性，直接关系到材料去除的均匀程度 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。轨迹分析显示，如果研磨盘上磨料分布不均或轨迹重复频繁，会导致工件某些区域去除过多、而另一些区域去除不足 (Influence of fixed abrasive configuration on the polishing process of silicon wafers | The International Journal of Advanced Manufacturing Technology) (Influence of fixed abrasive configuration on the polishing process of silicon wafers | The International Journal of Advanced Manufacturing Technology) 。方从富等人设计了两种磨料块排列的固定研磨垫（“规则矩阵型”和“径向变密度型”）在硅片上进行对比实验，结果发现径向变密度分布的研磨垫由于磨料轨迹在晶圆表面覆盖更均匀，其去除厚度的变异系数明显小于规则矩阵分布，因而晶圆全局平坦度和厚度均匀性更佳 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。该径向分布垫相比常规均匀分布垫使总厚度变动（TTV）减小，表明材料去除更加均衡。这表明，通过调控磨料在研磨盘上的空间分布图案，可显著改善工件材料去除的均匀性。

除了提高全局均匀性外，某些图案还能优化瞬态去除特性。Dong等 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 基于Preston公式建立了固定磨料研磨的去除模型，并通过多分布磨料块设计实现了去除形状的可预测和局部可控。他们证明固定磨料研磨的累计去除量随时间近似线性增加且稳定度可控制在±10%以内 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。这意味着合适的图案设计可确保研磨过程稳健受控，不会出现剧烈的速率波动，有利于精密加工。综上，研磨盘图案通过影响有效接触面积和磨料运动轨迹，对材料去除率及均匀性有重要作用：优化的图案往往在保证一定磨削接触的同时增进磨液流通和压力分布，进而提升去除速率并实现更加均匀的材料去除 (Effect of pad groove geometry on material removal characteristics in chemical mechanical polishing | International Journal of Precision Engineering and Manufacturing) (Zaixing Zhao's research works | Huaqiao University and other places) 。

对磨粒分布和磨屑排出的影响

研磨盘图案与沟槽直接影响磨料和磨屑在界面处的分布和运动，这进一步关系到去除机理和效率。磨粒分布方面，图案决定了磨粒相对于工件表面轨迹的密集程度和重复特性。理想情况下，各点磨粒经过工件表面的频次均匀，从而避免某些区域过度研磨或划伤。为量化这一点，研究者提出了轨迹分布均匀系数等指标。例如，方从富等人引入轨迹分布系数（CTD）来评价研磨垫磨料轨迹均匀性，通过模拟不同图案下磨粒轨迹密度的不均匀程度 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。他们针对仿生的花序螺旋图案进行优化研究，发现螺旋角度参数（决定图案类型）对轨迹均匀性影响显著，而螺旋密度参数影响相对较小 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。调整螺旋角度可以改变磨料块在盘面上的排布形态，从而改善轨迹覆盖的周期性和均匀度；通过优化这些参数，可设计出轨迹均匀性更高的图案。在他们的实验中，不同螺旋参数的固定磨料垫轨迹非均匀性NUT的取值范围从0.3降至0.1以下，验证了设计优化的有效性 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。总体而言，磨料轨迹分布越均匀，则对应的材料去除越均匀、加工质量越高 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。因此现代研磨盘图案设计常借助运动学仿真，力求各磨粒在工件上的路径覆盖趋于均一，以避免局部轨迹交叠不够或过度的问题 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。

磨屑与磨液的排出同样深受图案沟槽影响。研磨过程中产生的大量磨屑及反应副产物需要及时排出接触区，否则会造成研磨垫堵塞、磨粒钝化，甚至划伤工件表面 (CN212218161U - 一种沟槽研磨盘 - Google Patents) (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。沟槽提供了磨屑的容纳和流动通道。例如，同心圆环形沟槽呈封闭环结构，具有较强的蓄液与容屑能力，能快速将研磨液充满盘面各处，防止局部干摩擦 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。而螺旋形沟槽与旋转方向一致，可引导研磨液和磨屑呈螺旋路径流出，槽壁对流动阻力小，有利于磨屑的连续排出 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。一种新型的复合沟槽设计将同心圆和螺旋线结合，使研磨液既可沿螺旋槽快速流动，又可被同心槽暂存并均匀分配 (CN212218161U - 一种沟槽研磨盘 - Google Patents) (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。实验表明，相比无沟槽或普通单一沟槽的磨盘，这种复杂图案磨盘能够显著减少研磨时磨屑堵塞现象，始终保持良好的磨粒切削作用，使工件材料去除更充分且稳定 (CN212218161U - 一种沟槽研磨盘 - Google Patents) (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。在CMP研究中也有类似结论：例如Rosales-Yeomans等人发现，较深的沟槽可以提高磨料和浆料在垫下的流动，从而潜在地提高材料去除率并减少刮痕产生 (Effect of Pad Groove Designs on the Frictional and Removal Rate ...) 。然而必须注意沟槽过大会减少磨料实际接触面积，过度冲刷还可能导致磨料有效利用率降低 ([PDF] Effects of Pad Grooves on Chemical Mechanical Planarization - nckur) 。因此实际设计中往往需要在增进磨屑排出和保持磨料作用之间取得平衡 ([PDF] Effects of Pad Grooves on Chemical Mechanical Planarization - nckur) 。综合而言，合理的图案沟槽设计可以改善磨粒和磨屑在界面处的分布, 既保持磨粒切削的充分性，又将生成的碎屑快速移走，维持研磨过程的清洁稳定 (CN212218161U - 一种沟槽研磨盘 - Google Patents) (Effect of Pad Groove Designs on the Frictional and Removal Rate ...) 。

对工件表面质量的影响

研磨盘图案还显著影响工件表面的加工质量，包括表面粗糙度、形貌平整度以及亚表面损伤等。表面粗糙度往往取决于磨粒刻划的微观轨迹和切削深度。图案设计可通过改变磨料切削模式来影响表面纹理特征。例如，有研究通过对不同图案磨盘的模拟发现：** 螺旋形图案的研磨工具比同心圆图案**能够获得更好的工件表面质量，而采用同心圆图案加工时工件表面质量较差 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。这是因为螺旋图案使磨粒轨迹连续变化，避免了在同心圆图案下磨粒沿固定半径反复碾磨导致的环形纹印 (Zaixing Zhao's research works | Huaqiao University and other places) 。换句话说，螺旋槽引导下磨粒路径覆盖全面且无明显重复，从而减小了表面峰谷高度；而纯同心圆槽可能造成圆周方向的周期性纹理叠加于工件表面，增大粗糙度。实验验证也支持这一点：Wen等人通过模拟不同磨粒排列对磨削轨迹和已磨表面形貌的影响，报告指出螺旋图案磨盘加工的工件表面更光洁，而同心圆图案磨盘加工的表面出现较明显的同心划痕和质量劣化 (Zaixing Zhao's research works | Huaqiao University and other places) 。因此在需要高表面光洁度的应用中，通常会选择或优化使磨粒轨迹不呈现固定循环的图案，如螺旋、交叉网格或随机分布等，以降低宏观可见的划痕方向性和粗糙度。

平面度和形状误差方面，研磨盘图案主要通过影响材料去除的空间分布来作用。前述径向变密度磨料垫在硅片实验中已展现出更优的全局平坦度 (Zaixing Zhao's research works | Huaqiao University and other places) 。此外，对于大尺寸工件或要求极高平整度的加工，必须控制好边缘区域和中心区域的去除平衡。某些图案（如仅有环形槽）可能在盘面不同半径处去除率不同，导致工件中心与边缘平坦化不一致。而通过精心设计组合沟槽，例如在内、中、外不同半径区域采用不同槽距的同心沟槽（内外区域槽距较大，中间区域槽距较小），可调整各区域研磨压力分布，实现整体平坦 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。有研究通过将研磨盘分区并赋予不同图案密度，成功降低了加工后工件表面的整体弯曲度和畸变 (CN212218161U - 一种沟槽研磨盘 - Google Patents) (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。因此，不仅图案类型，图案分布的径向梯度也是平面度控制的重要考量之一。在需要高精度平面度的双面研磨中，也有通过优化上、下盘沟槽图案来抵消各自非均匀性的做法 (双图案非均匀耦合固结磨盘的设计及实验研究 - 中国光学期刊网) 。

亚表面损伤（SSD）和缺陷也是评价表面质量的重要指标，尤其对硬脆材料而言。磨盘图案通过影响单颗磨粒的切削深度和方式，对材料的脆性/延性去除模式有影响 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。Dong等针对碳化硅（SiC）和熔融石英（SiO_2）进行了固定磨料研磨的机理研究，发现两者达到延性去除模式所需的磨粒临界尺寸相差悬殊：SiC约为9.56 µm，而熔融石英仅约0.53 µm ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。这说明相比之下，熔融石英更易产生脆性破裂，需要极精细磨料才能避免表面裂纹。而在SiC研磨中，小于5 µm的固定金刚石磨料即可实现准延性加工，获得Ra约4.8 nm的光滑表面且无明显亚表面裂纹 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。研磨盘图案对此的意义在于：图案决定了单位面积承载的磨粒数目和每颗磨粒所受压力。如果图案设计过于稀疏，每颗磨粒承受的载荷增大，可能促使硬脆材料发生塑-脆转变，使其进入延性去除模式（从而减少SSD） (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) ；反之，图案过密则单颗磨粒负荷小，可能不足以实现延性切削，反而反复擦伤表面导致微裂纹不断累积。正因如此，针对不同材料需要选择合适的图案密度：例如，对于较软的脆性材料，通常采用密集一些的磨料排列以减轻单颗磨粒压强，避免深刮伤；而对较硬的脆性材料，则采用稀疏一些的排列以提高单磨粒切入深度，促进塑性去除 (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) 。这一原则在专利设计中得到体现：发明者建议蓝宝石等硬脆材料采用较稀疏的纵横平行或射线式排列，而K9玻璃等较软脆材料则用较密集的同心或螺旋式排列 (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) 。此外，微观结构的引入（如磨料块表面带有细微坑槽）也能降低单颗磨粒的犁沟作用，进一步减少划痕和亚表面损伤 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。总的来说，优化的图案设计可以在保证高效去除的同时最大限度降低表面粗糙度和亚表面损伤。实际报道的成果包括：采用冰粘结磨料垫实现接近无损伤的纳米级抛光 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 、利用复合结合剂磨料块抑制软脆材料深划伤并显著提高表面形貌精度 (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) 等。

研磨盘图案对研磨区域的温度场和力学响应也具有重要影响。热管理方面，沟槽的存在大大改善了研磨区域的冷却和散热条件 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。连续大面积接触研磨会在工件和磨盘界面产生显著热量，若不及时带走会导致工件热变形、表面烧伤甚至材料相变。图案沟槽通过增加磨削区的开孔率和液体流动通道，使冷却液（或浆料）更充分地进入接触界面并带走热量 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。例如，Lee等制备了一种开槽金刚石砂轮，实验证明其磨削温度比无槽砂轮降低了40%–80% (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。类似地，在钢轨磨削中，带有0.7间歇比、32条斜槽的CBN磨轮使磨削温度降低了15%–20%，同时加工表面粗糙度和损伤深度也随之减少 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。对于平面研磨盘而言，虽然转速和单位压力通常低于高速磨削，但热累积依然不可忽视。引入沟槽后，由于间歇接触形成**“热冲击-冷却”交替模式，可有效防止持续摩擦生热过高。螺旋沟槽还能促使研磨液在摩擦热驱动下循环流动，将热量不断带离磨区 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。实验观察表明，采用合理沟槽图案的研磨盘在长时间加工后工件表面未出现烧痕**，温升显著低于无沟槽情况 (CN212218161U - 一种沟槽研磨盘 - Google Patents) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。因此，图案设计在热管理上具有“双赢”效果：一方面降低工件热应力和热损伤风险，另一方面由于温度下降可抑制磨粒快速钝化和结合剂老化，从而延长研磨工具寿命 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。需要注意的是，过大的间歇可能引入热循环引起的热疲劳和振动（后述），因此沟槽参数需要综合考虑热、力因素 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。

在力学性能方面，图案主要通过改变接触刚度和力传递周期性来影响研磨力、振动及磨盘磨损。首先，磨削力和能量消耗普遍会因图案而降低。当研磨盘上存在沟槽或分块时，单次接触的受力面积减小，使切削力集中但接触为间歇过程。许多研究报道图案化磨具可降低平均磨削力和单位面积压力。例如，Denkena等的实验表明，经过图案化处理的砂轮可使磨削过程力下降约30% (Zaixing Zhao's research works | Huaqiao University and other places) 。槽的间歇效应让磨粒有短暂散热和自锐的机会，减少了过度挤压和摩擦，从而降低磨擦功和能耗。然而，力的周期性波动也随之引入，这可能产生加工颤振或啮合噪声等问题 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。在高速或高硬度材料加工时，研磨盘图案引起的周期冲击会诱发振动，导致表面出现波纹或“啸叫”痕迹，这是需要权衡的副作用 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。目前已有研究针对这一问题展开，如优化磨料块排列的相位使冲击错开，以抑制图案诱发的振动 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。

磨盘和磨粒的磨损亦受到图案影响。沟槽的存在会改变磨盘磨损的模式：没有沟槽时研磨垫整体均匀磨损，而开槽后可能出现槽边缘处磨粒磨损较快、沟槽区域基本无磨损的情况。总体上，由于图案缓解了磨粒持续工作，降低了温度和力，往往提高了研磨盘的耐磨寿命 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。例如，Lee等的开槽金刚石砂轮不仅降温明显，而且其材料去除率高于传统砂轮且磨损率更低 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。不过也有研究指出，增大间歇比虽然降低了研磨力，但也加剧了磨具自身的磨损 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。这可能是因为接触应力集中于较少的磨料块上，单位磨粒磨损加重。因此磨盘图案设计要兼顾工具寿命：通过调整槽数和深度，可控制磨盘应力水平 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。Yi等的模型计算表明，增多槽数同时减小槽深可以有效降低磨盘的最大应力，从而避免因沟槽造成磨盘结构削弱而引起的断裂或过度磨损 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。另外，磨盘图案还涉及修整（conditioning）问题：CMP中抛光垫需要用金刚石修整盘定期恢复表面形貌，对于固定磨料垫，如何修整沟槽和磨料块使其保持锋利且图案完整是一个挑战。一项针对固定磨料CMP垫的研究对修整引起的垫面磨损进行了分析，提出优化修整参数以延长图案寿命 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。综上，在力学性能方面，适当的图案设计可降低研磨力和能耗、延缓工具磨损，但需注意避免由于周期冲击导致的振动和由于应力集中过大的局部磨耗 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。

实验研究与数值模拟的总结

图案与沟槽设计对研磨性能的影响机制复杂多样，为深入理解和优化，研究者们采用了实验研究与数值模拟相结合的手段。下面对已有的重要实验结果和模拟工作加以系统回顾。

实验研究进展

大量实验对比了不同研磨盘图案在加工各种材料时的效果，这些研究为图案优化提供了直接依据。

在硅片研磨方面，方从富课题组进行了一系列实验。此前提到的比较规则矩阵型和径向变密度型磨料排列的实验中，他们使用溶胶凝胶法制作了对应的固定磨料垫并对200 mm硅片进行单面研磨 (Influence of fixed abrasive configuration on the polishing process of silicon wafers | The International Journal of Advanced Manufacturing Technology) (Influence of fixed abrasive configuration on the polishing process of silicon wafers | The International Journal of Advanced Manufacturing Technology) 。结果表明，径向型垫加工后硅片的全局形貌更平坦、厚度偏差更小、表面粗糙度更低 (Zaixing Zhao's research works | Huaqiao University and other places) 。这直接证明了优化磨料图案对硅片全局平面化的提升作用。另一项实验由Cong et al.（2018）进行，他们利用蜂群算法设计出一系列新型图案在蓝宝石晶片上进行了对比研磨 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。实验测量了工件表面轮廓、总厚度变化（TTV）、表面粗糙度和材料去除量等指标。结果发现，与传统图案相比，新设计的图案能显著降低TTV和粗糙度，同时提高材料去除效率 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。尤其是具有更低轨迹非均匀性的图案（NUT<0.1）表现出更优的研磨质量和效率 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。这组实验还指出，图案因素对研磨性能的影响超过工艺参数（如速度、压力）的影响，即选对图案比调整参数更加关键 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。

针对硬脆材料的实验也取得丰富成果。Dong等（2014）用不同粒径的固定金刚石磨料块研磨SiC和熔融石英，测得了实现延性去除的条件和所得表面品质 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。他们在SiC上获得了接近镜面的表面（Ra≈4.8 nm）和无明显亚表面损伤，而熔融石英在相同条件下仍有半脆性断裂的迹象 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。这说明固定磨料技术完全可以胜任对硬脆晶体的高精度研磨，但对玻璃等无定形材料还需更细颗粒和更优化图案来避免脆裂 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。另一项由胡忠伟等（2017）进行的实验聚焦于氧化铝陶瓷的研磨 (Speed ratio optimization for ceramic lapping with fixed diamond pellets | The International Journal of Advanced Manufacturing Technology) (Speed ratio optimization for ceramic lapping with fixed diamond pellets | The International Journal of Advanced Manufacturing Technology) 。他们设计了一种带有规则排列金刚石柱的固定磨料垫，并通过改变研磨盘与工件的转速比来考察轨迹分布对结果的影响 (Speed ratio optimization for ceramic lapping with fixed diamond pellets | The International Journal of Advanced Manufacturing Technology) (Speed ratio optimization for ceramic lapping with fixed diamond pellets | The International Journal of Advanced Manufacturing Technology) 。实验发现，当选用优化的转速比时，陶瓷工件获得了更好的平面度和表面粗糙度 (Speed ratio optimization for ceramic lapping with fixed diamond pellets | The International Journal of Advanced Manufacturing Technology) (Speed ratio optimization for ceramic lapping with fixed diamond pellets | The International Journal of Advanced Manufacturing Technology) 。这是因为最佳转速比下磨料轨迹分布最均匀复杂，从而减少了重复轨迹导致的凹坑和纹理 (Speed ratio optimization for ceramic lapping with fixed diamond pellets | The International Journal of Advanced Manufacturing Technology) (Speed ratio optimization for ceramic lapping with fixed diamond pellets | The International Journal of Advanced Manufacturing Technology) 。此外，他们记录的垫面磨痕显示，不同图案结构的垫对速度比变化十分敏感，说明图案结构与运动参数存在协同优化关系 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。这一系列实验强调了对硬质陶瓷材料而言，既要有高刚性的磨料图案保证足够切削力，又需通过运动学优化避免特定方向的纹理累积。

对于金属材料（如模具钢、铜等）的抛光实验相对较少，但已有一些探索。Choi和Jeong（2004）报道了一种亲水性固定磨料垫用于模具钢抛光 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。亲水性垫面图案旨在更好地保持磨液在界面润滑，减少金属加工中常见的黏附和划伤问题。虽然该文具体数据有限，但其表明通过改变垫材质和表面微结构（提高亲水性和磨液保持能力），可以在无需游离研磨液的条件下实现对金属模具的有效抛光 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。另外，在铜和钨等金属层的CMP中，Philipossian等研究了沟槽图案对磨垫摩擦和磨损的影响，发现不同沟槽会改变抛光时的剪切力谱特征，每种图案对应特有的摩擦噪声频谱 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。这从侧面说明图案对金属材料抛光中的力学响应和界面化学也有作用。整体而言，金属材料的固定磨料研磨实验还不够广泛，但已有结果显示，适当的图案设计（包括沟槽+表面润湿特性）有望提高金属表面的抛光效率并避免损伤。

数值模拟研究进展

数值模拟为研究研磨盘图案的作用机理提供了强有力的工具。主要的模拟手段包括磨粒运动学轨迹分析、流体动力学模拟、有限元/离散元应力场分析等。

轨迹分析与优化：这是图案设计中应用最广泛的模拟方法。通过建立研磨盘和工件相对运动的数学模型，计算每颗磨粒在工件上的路径覆盖情况，可以量化轨迹密度分布的不均匀性。早在1999年，Uhlmann等就通过运动学分析指出：研磨工具的运动参数会显著影响磨粒轨迹的分布，从而影响工件表面质量 (Zaixing Zhao's research works | Huaqiao University and other places) 。此后，大量工作采用轨迹模拟来指导图案设计和参数优化 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。例如，苏金喜等建立了硅片CMP中材料去除非均匀性的模型，将载体公转、自转等运动学因素纳入，成功解释了不均匀去除的产生原因并提出了优化策略 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。在固定磨料研磨中，方从富团队发展了多种基于轨迹的设计方法：如菲波纳契螺旋图案优化算法，通过调节螺旋参数使轨迹分布系数CTD最小 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) ；蜂群智能优化，利用类蜂群算法在给定参数空间内搜索轨迹非均匀性NUT最低的图案 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。这些模拟辅助设计已成功应用于实际，如前述蓝宝石研磨实验中新设计的图案即来源于NUT受限优化 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。因此，轨迹分析模拟已成为优化研磨盘图案的有效手段，能够在实验前筛选出较优的图案方案 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。

流体动力学（CFD）模拟：用于研究沟槽对浆料/冷却液流场的影响。CMP领域的一些模型将研磨垫表面视为多孔介质或带沟槽的结构，模拟浆料在垫-片间的流动与压力分布。例如，Muldowney（2005）探讨了沟槽尺度的浆料输运如何影响晶圆的纳米级平坦度 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。Guo等（2012）则引入浆料滞留时间（SDT）概念，用实验结合理论分析了沟槽宽度和节距对界面浆料平均滞留时间的影响，发现宽槽小节距能缩短浆料在界面的停留时间，从而使新鲜浆料更快补充进入，提高磨削效率 (Effect of pad groove geometry on material removal characteristics in chemical mechanical polishing | International Journal of Precision Engineering and Manufacturing) (Effect of pad groove geometry on material removal characteristics in chemical mechanical polishing | International Journal of Precision Engineering and Manufacturing) 。后来的一些CFD模拟进一步验证，不同沟槽形状（如直槽 vs. 倾斜槽）下界面流场分布差异明显：倾斜或斜交的沟槽有助于形成均匀的压力场和流速场，改善边缘部位的化学机械作用 (Effect of concentric slanted pad groove patterns on slurry flow during ...) 。同时也有模拟指出沟槽增加会降低浆料在垫面上的总体滞留量（因为大部分浆料直接通过沟槽流走），从而存在最佳槽尺寸以兼顾浆料供应和利用率 (Effect of pad groove width on slurry mean residence time and slurry ...) (Effect of Pad Groove Designs on the Frictional and Removal Rate ...) 。这些模拟结果为研磨垫沟槽设计提供了定量依据，比如推荐一定范围的槽宽/槽距组合以平衡去除率和均匀性 (Effect of pad groove width on slurry mean residence time and slurry ...) (Effect of concentric slanted pad groove patterns on slurry flow during ...) 。在固定磨料研磨的CFD应用中，还有研究将研磨液简化为薄膜流，在旋转圆盘上模拟磨粒被液流驱动的分布，考察了液膜厚度和旋转速对磨粒扩散的影响 (Zaixing Zhao's research works | Huaqiao University and other places) 。总的来说，流体模拟揭示了沟槽对界面润滑和磨粒输运的作用，可以优化沟槽形状以减少局部干摩擦和提高浆料利用率 (CN212218161U - 一种沟槽研磨盘 - Google Patents) (Effect of Pad Groove Designs on the Frictional and Removal Rate ...) 。

力学和磨损模拟：包括有限元（FEM）和离散元（DEM）模拟，用于研究研磨过程中的应力分布、磨粒与工件相互作用以及工件材料去除机理等。FEM常用于分析研磨盘在开槽情况下的应力集中和变形。例如，有学者建立磨盘槽结构的三维有限元模型，计算不同槽深和槽数下磨盘所承受的等效应力，证明槽深过大可能削弱盘体刚度而引发过量变形 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。这一结果指导制造中避免过深沟槽或使用分段式沟槽以兼顾结构完整性 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。DEM则适合模拟大量磨粒的集体行为。一些研究以单颗磨粒切削为基础，叠加随机分布磨粒来模拟整体研磨效果。例如，国内有工作利用离散元建立了固定磨料研磨ZnS晶片的模型，通过单磨粒刻划的力学响应预测了不同粒径磨料引起的亚表面损伤深度 ([PDF] 固结磨料研磨硫化锌的亚表面损伤预测分析 - Researching) 。结果表明，磨粒粒径越大，ZnS由弹塑性转为脆性破坏的临界深度越浅，因而大磨粒更易产生深层裂纹 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。这一模拟与Dong等的实验结论一致 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。另外，Smith等使用三维随机磨粒模型，计算了研磨过程中工件表面受力分布，发现当磨粒排列有序时研磨力波动较大，随机排列则力波动小但局部应力峰值更高 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。这提示在磨粒图案设计上需考虑随机性引入来平滑力学冲击。磨损模拟方面，Nguyen等建立了固定磨料CMP垫在钻石修整下的磨损模型，预测了不同图案垫的磨损率并与实验吻合 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。他们的模型可用于估计磨垫寿命，从而优化图案使之在整个寿命周期内性能变化最小。总的来说，力学模拟为理解研磨力、应力场和损伤形成提供了细节，可用于改进图案设计以降低不利应力峰值、防止宏观振动和延长工具寿命 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。

不同材料加工表现的差异分析

研磨盘图案优化往往需要针对具体工件材料进行调整，不同材料在物理性质（硬度、脆性、热敏感性等）上的差异使其在固结磨料研磨中的行为有所不同。以下分别讨论硅片、陶瓷、金属和蓝宝石等材料在图案研磨盘加工下的特性差异。

硅片（硅晶圆）

单晶硅片是半导体制造的关键基底材料，对其表面平整度和缺陷密度要求极高。硅属于硬度中等（莫氏硬度~7）、具有一定延展性的材料，在研磨中既存在机械去除也伴有化学作用（如CMP中） (Mechanical aspects of the chemical mechanical polishing process: A review | International Journal of Precision Engineering and Manufacturing) 。针对硅片，全局平坦化（全局平面度）和片内厚度均匀性是主要考核指标。优化图案在硅片研磨中侧重于保证整个晶圆表面材料去除量的一致。前述实验已经表明，采用径向非均匀分布磨料的固结磨料垫可以显著提高硅片厚度均匀性 (Zaixing Zhao's research works | Huaqiao University and other places) 。这是因为径向渐变图案能够补偿晶圆中心和边缘因相对速度差异带来的去除不均 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。在双面研磨中，通常上盘和下盘同时作用于硅片，其各自图案设计和转动方式亦影响硅片厚度分布 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。Tso等研究了双面研磨机中载体运动方式对硅片非均匀性的影响，建议通过调整上下面相对旋转以及选择合适图案，可消除硅片旋转引起的抛光非均匀 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。另外，硅片表面微观缺陷（如纳米级起伏）在CMP中与垫上沟槽尺寸有一定关系。Muldowney（2005）的研究指出，垫上沟槽的尺度会影响浆料在 wafer 纳米不平度处的局部流动，从而可能放大或抑制纳米级皱褶 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。因此，为实现硅片的超平坦，有人提出亚微米尺度的垫面微图案设计来过滤掉特定波长的形貌误差 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。目前，硅片CMP普遍采用带棋盘格沟槽或同心细槽的抛光垫，以在兼顾大规模平坦化的同时减小小范围的不平度 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。总之，硅片加工强调全局/局部平坦度的统一优化，图案设计需保证整个晶圆面均匀加工且不引入周期印痕，径向可变沟槽或高密度细沟槽是常用策略 (Zaixing Zhao's research works | Huaqiao University and other places) (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。

硬脆陶瓷

硬脆陶瓷材料包括晶体（如蓝宝石、SiC）和非晶（如玻璃、石英等）两大类。它们通常硬度高、脆性大、抗拉强度低，研磨中容易产生微裂纹和亚表面损伤。对于这类材料，图案设计的要点在于促进延性去除、降低脆裂倾向，并控制温度避免热裂。实验与模拟均表明，磨粒尺寸/负载与材料脆-延转变密切相关 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。因此，研磨盘图案通过影响单颗磨粒受力，能够部分调控去除模式。针对较硬的脆性晶体（SiC、蓝宝石等），建议采用稀疏型图案，例如磨料块排列较为松散的放射状或矩阵状，使每颗磨粒承担较高压力以切入材料实现微塑变形 (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) 。前文提到Dong等成功用1.5–5 µm金刚石磨料对SiC进行延性研磨，获得光学级表面 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) 。这使用的是多分布磨料块抛光垫，可推测其磨料间距和分布经过优化以提供足够的单位压力又不致引发表面崩裂。相反，对于相对较软且极脆的材料（如石英玻璃），则倾向使用密集型图案，让众多磨粒分担载荷，每颗磨粒切削浅而广，从而避免深划伤 (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) 。例如，在K9玻璃等软玻璃研磨中，有研究采用同心圆+螺旋的双图案高密度磨料垫，结果表面划痕显著减少，粗糙度下降 (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) 。另外，硬脆材料对温度非常敏感，局部高温可能引起热应力裂纹。因此沟槽在此类材料加工中特别重要——要保证磨削区充分冷却 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。蓝宝石等热导率低的晶体如果持续干磨极易烧伤开裂。采用螺旋-同心复合槽的研磨盘研磨蓝宝石时，实验观察到工件无烧伤，表面残余应力降低，推测是沟槽有效控制了磨区温度 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。总体来讲，硬脆陶瓷材料加工需要图案和工艺的联动优化：通过图案选择合适的磨粒负荷水平，并配合适当磨料细度和冷却条件，以实现延性断裂控制和高质量表面 ((PDF) Study on removal mechanism and removal characters for SiC and fused silica by fixed abrasive diamond pellets) (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) 。

金属材料（如钢、铜、铝合金等）的机械加工特点是延展性强、易变形发热、可能出现黏附。固定磨料研磨金属时，主要挑战在于避免磨料和工件间发生黏着磨损（smearing）以及由延性加工引起的毛刺、残余应力等。相对硬脆材料，金属在研磨中更少产生碎屑颗粒，而是形成连续卷屑或糊附在磨粒上，容易堵塞磨盘。因此，对金属研磨盘图案设计的关键是加强润滑、排屑和散热。一般采用沟槽高度开放的图案，如宽而深的沟槽，甚至是镂空的分块结构，以提供足够大的容屑空间和通风冷却通道 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。例如，在不锈钢表面抛光中，常用螺旋沟槽铜盘或有槽树脂垫，以便将磨屑及时移走，防止在工件表面拖拉划伤 (CN203918808U - 一种蓝宝石抛光用铜盘- Google Patents) (Styrolution PS 1611 - GPPS) 。Choi等的亲水性固定磨料垫在抛光模具钢时表现出良好效果，正是因为亲水涂层和沟槽共同确保了磨液充分润滑和碎屑带出 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。他们的研磨垫在整个加工过程中保持了稳定的摩擦力，没有出现研磨垫加载（金属碎片嵌入垫面）的问题，模具表面粗糙度也满足要求 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。对软金属（如铜），CMP中发现沟槽图案影响磨擦和振动：某些沟槽可降低刮板力并抑制振动，从而减少大面积铜面上的摩擦条纹 (Effect of Pad Groove Designs on the Frictional and Removal Rate Characteristics of ILD CMP | Request PDF) 。此外，金属较硬脆材料更能容忍较高温度，但局部过热仍会导致退火变色或机械性能下降，故沟槽冷却在高荷载金属研磨中同样必要 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。综合考虑，金属材料适宜开槽率较高的研磨盘图案，辅以良好润湿，以防止堵塞、降低摩擦和热积累。磨料方面，金属延性大可能导致磨粒“堵塞钝化”，因此有时在垫面引入自锐性结构（如微凸起）帮助磨粒在加工过程中不断出露新的锋利刃口 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。总之，对金属工件而言，图案设计强调排屑降温优先，以保障加工表面无划伤烧伤并维持磨粒切削效率。

蓝宝石

蓝宝石（单晶Al_2O_3）因硬度高达莫氏9、脆性大、化学惰性强，常被视为难加工材料，广泛用于LED基板等。蓝宝石的加工要求通常是高效去除硬度损伤层并获得极低的表面粗糙度。针对蓝宝石的研磨盘图案优化是近年研究热点 (双图案非均匀耦合固结磨盘的设计及实验研究 - 中国光学期刊网) 。传统单一沟槽磨盘在加工蓝宝石时容易出现加工质量不稳定的问题 (双图案非均匀耦合固结磨盘的设计及实验研究 - 中国光学期刊网) 。这是由于蓝宝石硬且各向异性强，如果轨迹分布略有不均，就可能在某晶向引发微裂纹扩展，导致局部质量劣化。为此，方从富等提出了双图案非均匀耦合磨盘（DPP），即将同心圆和螺旋沟槽相结合用于蓝宝石研磨 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。该设计初衷正是为了解决传统单一图案难以兼顾蓝宝石加工效率和质量的难题 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。实验结果显示，这种复合图案磨盘相较普通沟槽盘，能使蓝宝石工件获得更低的表面粗糙度和更优的平坦度，加工效率也明显提升 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。背后的原因在于，双图案一方面强化了磨削液流动和排屑（螺旋槽作用），另一方面维持了磨料全面均匀接触（同心槽作用），从而将蓝宝石的高硬度高脆性加工需求平衡得更好 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。另外，Cong等通过调整双图案的具体参数（如螺旋导程、同心槽间距比例），可以进一步降低轨迹非均匀性NUT，使蓝宝石表面TTV降至1 µm以下，Ra降至亚纳米级 (Zaixing Zhao's research works | Huaqiao University and other places) (Zaixing Zhao's research works | Huaqiao University and other places) 。除双图案外，另一些研究也尝试对蓝宝石磨盘进行创新设计。例如，有人研究了磨盘柔性衬垫与刚性磨料块的组合，通过在磨盘背面增加阻尼层吸收部分冲击来减少蓝宝石表面的微观震痕 (Optimal design and experimental study of fixed abrasive pads based ...) 。总之，蓝宝石的固定磨料研磨需要综合考虑高硬度材料的去除速率与防裂两方面：既要强力切削又不能引发脆裂。复杂图案（如双图案）、优化运动参数（如避免简单周期运动）以及特殊结构（如柔性支撑）等都是为实现这一目标服务的手段。从现有成果看，针对蓝宝石等超硬晶体材料，优化的复合图案研磨盘已能在保证加工效率的同时，将表面粗糙度和损伤控制在极低水平，满足光学及电子应用要求 (CN212218161U - 一种沟槽研磨盘 - Google Patents) (Zaixing Zhao's research works | Huaqiao University and other places) 。

当前研究存在的不足与未来展望

尽管研磨盘图案与沟槽设计的研究已取得丰硕成果，但仍有诸多问题有待深入，未来亦有广阔的发展空间。

(1) 振动和稳定性问题： 图案引入了间歇式的研磨接触，虽然降低了平均力和温度，但由此产生的周期性冲击可能引发磨削颤振和噪声 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。目前对磨盘图案导致的振动效应认识尚不充分，尤其是在高精度场合，小幅振动也会影响表面形貌。未来需要开展对图案诱发动态效应的系统研究，包括建立模型预测哪种图案容易产生谐振、如何通过设计避开敏感频率等。此外，应探索抑制颤振的图案优化策略，例如不完全周期的随机图案、错位块排列等，以消除因周期碰撞引起的颤振 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。提升加工过程的平稳性，将有助于进一步降低表面波纹度和提高尺寸精度。

(2) 图案类型与尺度的多样化不足： 当前研究中使用的图案类型相对有限，多集中于几何上规则的槽形或阵列。实际上，优化的图案形貌可能并非规则。例如，磨盘表面微结构（小坑、小凸台）的排列和尺寸也会影响切削行为 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。然而这方面研究较少，很多微结构设计尚属经验。未来应加强对新型图案的探索，包括非规则自适应图案（如分形结构、随机点阵）以及多尺度复合图案（大沟槽+微织构相结合）等 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。通过仿真与实验相结合，寻找在不同尺度上都优化的图案，从而进一步提高研磨性能。另外，人工智能优化算法（遗传算法、强化学习等）在复杂图案设计中大有可为，可用于发掘人脑难以直观想到的图案方案。丰富的图案库和优化设计手段将为不同行业需求提供更佳解决方案。

(3) 图案制造与保持技术： 再精妙的图案设计都需要可靠的制造手段实现。目前沟槽主要通过机械加工或激光刻蚀得到，但对于复杂三维图案或梯度分布图案，这些方法成本较高或精度受限 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。增材制造（3D打印）和精密铸造（如消失模法）等新技术有望用于研磨盘模具的快速制造 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。例如，前文提到采用消失模工艺一次成型复杂沟槽模具，具有工艺简单、效率高、成本低的优势 (CN212218161U - 一种沟槽研磨盘 - Google Patents) 。未来应进一步开发高精度、低成本的图案制造工艺，以便在工业上大规模推广定制化研磨盘。同时，研磨盘图案在使用过程中会逐渐磨损或充填，需要在线修复和保持。如何在不拆卸的情况下通过在线修整恢复图案功能，是一个具有挑战性的课题。一些初步研究尝试了在机电解修整或激光再刻槽的方法，但需要确保修整不会引入新误差 (Pattern design of fixed abrasive pads inspired by the bee colony theory | The International Journal of Advanced Manufacturing Technology) 。因此，研制专用的图案修整工具和智能监测补偿系统将是未来的重要方向，保证研磨盘始终保持最佳图案形貌。

(4) 材料特性与图案设计的深度结合： 目前针对不同材料提出了若干经验性的图案选择指导，但其背后的机制尚未完全清楚。例如，为什么软脆材料更适合密集图案、硬脆材料适合稀疏图案，仅有定性解释 (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) 。未来需要从材料去除机理角度，将材料力学性能（硬度、断裂韧性、导热系数等）与图案参数建立定量关联模型。例如，可否根据材料的延性-脆性转变临界条件，计算出所需磨粒接触压力范围，从而反推出合适的磨料块间距和尺寸。这种材料-图案匹配模型将使设计具有科学依据，减少反复试验。类似地，不同材料的磨屑形态和摩擦学行为差异很大，也需要相应的图案去应对（如金属的防黏附图案，陶瓷的降温图案等）。因此，加强材料去除行为的基础研究，结合高级仿真手段（如原子/分子动力学模拟了解纳观去除机制），将为图案设计提供更深层指导。

(5) 绿色制造和能耗： 固结磨料研磨本身具有减少游离磨料污染的优点，但研磨盘图案的合理设计还能进一步降低加工能耗和磨料浪费 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。研究表明，有序磨料排列的磨具由于冷却润滑充分、力学性能优化，可显著降低磨削比能和磨具损耗 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。未来应以绿色加工为导向，评估不同图案的能量利用效率和磨料利用率，开发出低能耗、长寿命的最佳图案方案。同时，随着对研磨过程环境影响要求提高，可考虑设计可降解或可循环的磨料块/沟槽结构，例如在磨盘用尽后易于分离再生。这方面需要材料科学与设计制造的协同创新。

(6) 特殊应用领域拓展： 目前图案设计主要服务于平面抛光和平坦化，但实际上通过控制磨盘图案，还可以在工件表面赋予功能性纹理 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。一些研究设想利用特定图案的磨具直接在工件上加工出预定的表面花纹或织构（例如在光学表面产生消眩纹理，在轴承表面产生储油坑槽等） (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。这将要求反向思考：先定义希望在工件上形成的表面图案，再倒推需要怎样的磨盘结构 (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。目前对此类“以纹理换纹理”的加工方法研究甚少，是一个有趣的方向。随着数字化制造的发展，未来不排除研磨盘图案会与主动控制结合，例如可动态改变图案以实现自适应加工不同区域。这将在智能制造背景下提供全新可能。

总结

平面固结磨料研磨中研磨盘图案与沟槽设计对加工性能有着深远影响。本文综述了研磨盘图案的主要类型（沟槽型与磨料块型）及其结构特点，阐明了图案和沟槽如何通过改变磨粒轨迹分布、磨屑流动、界面温度和受力状态来影响材料去除率、表面质量和研磨稳定性等关键指标。大量实验研究和数值模拟一致表明：优化设计的图案（例如合理宽深比例的沟槽、均匀覆盖的磨料排列、复合螺旋-环形结构等）能够显著提高研磨效率和均匀性，降低工件表面粗糙度与亚表面损伤，并改善热管理和磨具寿命 (Effect of pad groove geometry on material removal characteristics in chemical mechanical polishing | International Journal of Precision Engineering and Manufacturing) (CN212218161U - 一种沟槽研磨盘 - Google Patents) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text) 。同时，不同材料在图案选择上存在差异：硅片注重全局平坦化需轨迹密度均匀，硬脆陶瓷需兼顾延性去除和冷却，金属材料强调排屑防黏附，蓝宝石等超硬晶体则需要复合图案以平衡高效去除与防止脆裂。 (CN104385118A - 一种金刚石丸片及其应用方法、研磨工具 - Google Patents) (CN212218161U - 一种沟槽研磨盘 - Google Patents) (Research Progress of Abrasive Groups Ordered Grinding Wheels | Chinese Journal of Mechanical Engineering | Full Text)

尽管当前研究已取得重要进展，但在抑制图案诱发振动、开发新型复杂图案、提高图案制造与保持能力、建立材料-图案匹配模型以及绿色加工和功能化应用等方面仍有提升空间。展望未来，随着先进制造技术（如智能算法设计、增材制造和自适应控制）的引入，研磨盘图案设计有望变得更加科学、高效和智能。研磨盘不再只是被动的耗材，其表面图案将成为可工程化定制的“功能结构”，针对不同工艺和材料实现最佳性能。可以预见，围绕研磨盘图案与沟槽的研究将在半导体制造、光学加工、精密工程等领域发挥日益重要的作用，为实现更高精度、更高效率和更环保的加工工艺提供关键支持。今后的研究需要多学科融合，从理论和实践上共同推进这一领域的发展，使固结磨料研磨技术不断迈上新台阶。
