Description

多用途非线性半导体封装体装配线
本申请是申请日为2017年10月09日、申请号为201710929897.X、发明名称为“多用途非线性半导体封装体装配线”的发明专利申请的分案申请。
技术领域
本申请涉及半导体封装,更尤其涉及高容量封装体装配线。
背景技术
半导体封装用于保护集成电路(例如微处理器、微控制器、ASIC装置、传感器、功率晶体管等),并且在集成电路与外部部件、例如印刷电路板之间提供电和热接口。通常,半导体封装体被设计成保护集成电路免受潜在的破坏性环境条件、例如极端温度变化、湿气、灰尘颗粒等。此外,半导体封装体包括在集成电路的端子与外部部件之间提供电接口的外部端子(例如引线、焊盘等)。
随着半导体工业的发展,已经开发出各种不同的封装体类型。开发的第一种封装体类型之一是所谓的TO(晶体管外形:transistor outline)封装体,所述TO封装体包封例如晶体管或二极管的单个半导体裸片,并且包括直接从包封部分延伸出的两个或三个引线。TO封装体之后的一种封装体类型是所谓的DIP(双列直插封装体:dual in-linepackage),它比TO封装体提供了更高的引线数和更多的I/O容量。DIP封装体之后的一种封装体类型是所谓的QFP(四方扁平封装体:quad-flat-package),由于在封装体的四侧都提供“鸥翼”型引线,因此QFP提供了高引线数。从那里,演化了所谓的表面贴装封装体。表面贴装封装体包括用平焊盘代替引线,因此减小了空间。表面贴装封装体的一个例子是BGA(球栅阵列:ball grid array),所述BGA具有位于封装体的底侧的焊料球格栅阵列,所述焊料球格栅阵列用于提供外部电端子。
迄今为止,存在大量可商购并广泛使用的标准封装体类型。这些封装体类型的例子包括DIP(双列直插封装体:dual in-line package)、LGA(接点格栅阵列:land gridarray)、MCM(多芯片模块:multi-chip module)、LCC(带引线的芯片载体:leaded chipcarrier)、PGA(引脚格栅阵列:pin grid array)、CFP(陶瓷扁平封装体:ceramic flatpack)、QFN(四方扁平无引线:quad flat no-leads)、TSOP(薄型小外形封装体:thinsmall-outline package)和WLB(晶片级球栅阵列:Wafer Level Ball Grid Array)。这些封装体的内部结构有很大的差异,并且用于制造这些封装体类型中的任何一种的工艺显著不同。布线技术可以变化(例如引线接合、焊料突起、薄膜附接等)。包封技术可以变化(例如传递模制成型法、压缩成型、层压等)。激励人们优选封装体类型和工艺技术的驱动因素包括成本、电性能、热性能、互连密度、系统集成容量和可靠性。通常,在产品的生命周期中,性能最初是最重要的考虑因素,但随着产品在其生命周期中逐步发展,成本成为主导因素。
降低封装体装配成本的一种方法是利用并行加工技术。并行加工是指在多个封装位点上同时进行相同的封装工艺(例如引线接合、裸片附接、包封等)的技术。该技术的一个例子涉及使用具有大量(例如10、20、50个等)相同的单元细胞的引线框架条,每个单元细胞具有期望封装体类型的引线结构。引线框架条被装载到各种封装工具(例如裸片附接工具、模制成型工具、引线修整工具等)中,并且封装体加工同时应用于引线框架条中的每个单元细胞。最终,单元引线框架被单个化并且产生了许多相同的封装体。
到目前为止,封装体装配线被构建以生产单个封装体类型(例如CFP、QFN、TSOP等)。每个封装体装配线都需要投资、规划、材料建造、流程设计、工具设备和专门仅生产一种类型的封装体的制造位置。这些因素导致每个封装体的成本增加。
发明内容

根据另一个实施例,所述方法包括提供第一和第二封装衬底面板,每个面板包括多个封装位点。提供包括被配置为对第一和第二面板中的每个封装位点执行封装体加工的多个加工工具的装配线。提供控制机构,其被配置为识别第一和第二封装衬底面板并且以非线性方式将第一和第二面板装载到装配线中的每个加工工具中。使用控制机构使第一面板移动通过装配线,以形成第一封装体类型封装体。使用控制机构使第二面板移动通过装配线,以形成与第一封装体类型不同的第二封装体类型封装体。控制机构将第一面板仅装载到装配线中生产第一封装体类型所需的那些加工工具中、将第二面板仅装载到装配线中生产第二封装体类型所需的那些加工工具中。
根据另一个实施例,所述方法包括提供多个封装衬底面板,每个面板具有相同的尺寸并且为至少24英寸×18英寸。提供具有与24英寸×18英寸面板兼容的多个加工工具的装配线。装配线中的第一组加工工具被配置为执行第一封装体类型的每个封装体加工步骤,并且装配线中的与第一组不同的第二组加工工具被配置为执行与第一封装体类型不同的第二封装体类型的每个封装体加工步骤。提供控制机构,其被配置为能识别装配线中的衬底面板并且将识别出的面板装载到第一组和第二组中的任何一个加工工具中。控制机构用于识别封装衬底面板并且确定识别出的面板包括第一封装体类型封装位点还是第二封装体类型封装位点,在识别出的面板包括第一封装体类型封装位点的情况下将识别出的面板装载到第一组中的一个加工工具中,并且在识别出的面板包括第二封装体类型封装位点的情况下将识别出的面板装载到第二组中的一个加工工具中。

具体实施方式
本文描述的实施例包括同时以各种不同封装体类型(例如CFP、QFN、TSOP等)封装多种半导体装置的方法。这些封装体使用在制造过程中适于所需封装体类型的面板生产。所述面板的尺寸可非常大(例如18英寸×24英寸)。每个面板的封装位点的准确数量将随封装体类型和封装体尺寸而变化。以8平方毫米的封装体占用面积为例,这些非常大的面板中的一个可用于生产大约4,000个封装体。装配线中的每个封装体装配工具都与这些非常大尺寸的面板兼容,并且可以对这些面板上的每个封装位点执行封装体构造步骤。所述封装体装配工具的实例包括模制成型工具、引线接合机、层压机、喷射清洁工具、金属镀覆工具等。通过在装配线中使用非常大的面板尺寸,增加了并行化并且降低了每个封装体的成本。
根据本文描述的有利的实施例,非线性装配线与面板移动控制机构结合使用,以便同时对不同封装体类型执行必需的加工步骤。根据非线性加工技术,封装体批次(即,面板或面板组)不是以线性次序顺序地从一个封装体装配工具传送到下一个封装体装配工具来通过装配线。相反,与第一封装体类型(例如QFN)相关联的特定封装体批次移动通过与第一封装体类型相关联的所选的一组封装体装配工具。同时,与第二不同的封装体类型(例如WLB)相关联的第二封装体批次经过与第二封装体类型相关联的不同组的封装体装配工具,并且可以以不同的次序移动通过公共的加工工具。换句话说,非线性工艺能够基于封装体类型完全地改变加工步骤的次序并且跳过或添加加工步骤。这可以通过能够在每个加工步骤完成之后将一封装体批次移动到装配线中的任何一个加工工具的控制机构实现。控制机构识别每个批次,确定在所识别的批次中包含哪种封装体类型,并将所述批次装载到适当的加工工具(或适当的加工工具队列)中。以这种方式,控制机构控制封装体批次通过装配线的流动,并且确保每个批次仅放置在生产与这些批次相关联的封装体类型所必需的那些加工工具中。此外,控制机构可以通过监测加工工具的可用性和/或延迟时间并且基于负载平衡方案装载所述加工工具来优化系统产量。
参考图1,示出了根据一个实施例的传统的线性封装体装配线100。这种常规的装配线形式适用于各种常见的封装体类型(例如,MCM、LCC、PGA、CFP、QFN、TSOP等)中的任意一种。然而,这种传统的线性封装体装配线100通常只能生产这些封装体类型中的一种。也就是说,所述传统的线性封装体装配线100仅包括那种生产某种封装体类型的加工工具,并且物理上以生产这种封装体类型的方式布置。所述传统的线性封装体装配线100包括总共五个加工工具,即第一加工工具102、第二加工工具104、第三加工工具106、第四加工工具108和第五加工工具110。这些加工工具可以被配置为执行诸如引线接合、蚀刻、层压、注射成型、喷射清洁、电镀、蚀刻、引线修整、切割等封装步骤。对于引线框架式封装体,所述加工工具可以被配置为在每个引线框架中装载和加工具有多个单元引线框架的引线框架条。
传统的线性封装体装配线100是线性的,这意味着在通过所述加工工具之一在封装体批次之一上完成封装体加工步骤之后,所述封装体批次必须前往下游加工工具之一。因此,封装体批次流经加工工具的次序总是相同的。在这点上仅有的灵活性是可以跳过次序中的一个或两个以上步骤,并将所述封装体批次送往更下游的加工工具。这个原理通过图1中为两个不同封装体批次提供的两个工艺流示出。第一封装体批次112线性地流过装配线而直接从第一加工工具102到第二加工工具104,然后直接从第二加工工具104到第三加工工具106,然后直接从第三加工工具106到第四加工工具108,再然后直接从第四加工工具108到第五加工工具110。第二封装体批次114线性地流过装配线而直接从第一加工工具102到第二加工工具104,然后直接从第二加工工具104到第四加工工具108,再然后直接从第四加工工具108到第五加工工具110。因此,第二封装体批次114跳过了第三加工工具106。然而,第一和第二封装体批次112、114都在相同的线性方向上流过传统线性封装体装配线100的加工工具。
通常,在例如参考图1描述的示例性装配线100的线性装配线中,加工工具需要不同的时间量来执行它们相应的封装步骤。这在加工工具之间需要缓冲,并在工艺中产生降低产量的瓶颈。
参考图2,示出了根据一个实施例的非线性封装体装配线200。所述非线性封装体装配线200总共包括十五个加工工具,即第一加工工具202、第二加工工具204、第三加工工具206、第四加工工具208、第五加工工具210、第六加工工具212、第七加工工具214、第八加工工具216、第九加工工具218、第十加工工具220、第十一加工工具222、第十二加工工具224、第十三加工工具226、第十四加工工具228和第十五加工工具230。所述加工工具被分组成多簇,即第一簇250、第二簇260、第三簇270、第四簇280和第五簇290。每簇包括三个加工工具。这只是一个例子,加工工具的总数、簇的总数以及每簇中的加工工具数量可能会有所不同。
所述装配线200是非线性的,这意味着在封装体批次在加工工具中的一个中完成加工之后,所述封装体批次可以前往装配线200中的任何一个加工工具,包括之前已经用于这个封装体批次的任何加工工具。因此,与参考图1描述的线性封装体装配线100相比,可应用于特定封装体批次的潜在的加工步骤要高几个数量级。此外,两个不同的封装体批次可以同时地通过非线性装配线200并接收独有的封装体加工。例如,第一封装体批次可以通过装配线200并接收对于第一封装体类型(例如,VQFN、SON、TON等)来说独有的封装体加工,第二封装体批次可以通过装配线200并接收对于第二种封装体类型(例如,无引线DS、eWLB、WLB等)来说独有的封装体加工。一种封装体类型而不是其它封装体类型所需的多种加工步骤可以同时地在第一和第二封装体批次上执行。这在使用参考图1描述的传统的线性装配线时是不可能的。
所述非线性封装体装配线200包括控制机构232,所述控制机构232便于在制造中使各种封装体批次移动通过装配线200。控制机构232例如负责将封装体批次装载到非线性封装体装配线200中的各种加工工具中,在封装体加工完成之后从各种加工工具移除所述封装体批次,并且将正在制造的封装体批次中的每一个传送到正确的加工工具以用于后续加工。
所述控制机构232被配置为识别正在制造的封装体批次中的每一个。这可以通过在每个封装体批次上提供独有的标识符并且提供被配置为检测独有的标识符的相应机构来完成。例如,每个封装体批次可以包括条形码,并且控制机构232可以包括条形码检测装置。替代性地,多个条形码检测装置可以分布在整个装配线200上并且具有与控制机构232的通信连接(例如,无线或有线连接)。根据另一示例,每个封装体批次可以包括RFID发射器,并且控制机构232可以包括RFID接收器或连接到分布在整个装配线上的多个RFID接收器。
所述控制机构232被配置为使用每个封装体批次的识别信息来确定什么封装体类型与所识别的封装体批次相关联。例如,控制机构232可以确定所识别的封装体批次是否包括TSLP型封装体、SSO8型封装体、VQFN型封装体、扇出晶片级封装(例如eWLB)型封装体等。这可以使用将特定封装体批次的独有标识符与封装体类型相对应的查找表来完成。例如,查找表可以存储在控制机构232的存储器中。替代性地,封装体类型信息可以并入每个封装体批次的标识符中。
所述控制机构232可以在制造中的每个封装体批次的各种加工步骤中的任何一种或所有加工步骤中执行对所述封装体批次的识别。例如,控制机构232可以在非线性装配线200的每个加工工具的出口点处执行封装体识别。替代性地,当封装体批次通过非线性装配线200的中心核时,可以仅在每簇的出口点之后进行封装体识别。
所述控制机构232被配置为确定制造中的每个封装体批次已经完成的加工步骤的序列和仍然需要的加工步骤的序列。这可以使用存储在控制机构232的位于中心的存储器中的目录来完成,所述目录将每个批次与安排好的步骤列表相关联,并且指明这些步骤中的哪些步骤已经完成。替代性地,该信息中的一些或全部可以存储在封装体批次本身上。使用SS08封装体类型作为一个示例,控制机构232可以确定特定批次已经接收到加工步骤,包括层压、芯片附接、等离子体清洁、印刷和裸片附接。控制机构232可以确定这个特定批次仍然需要的加工步骤,包括(按此顺序)压缩成型、研磨、激光打标、松脱、铜蚀刻、层压、电镀、清洁和分离。基于该确定,控制机构232确定所需的下一个加工步骤是压缩成型,因此发送所述特定批次到压缩成型工具。一旦这个过程完成,控制机构232执行更新的识别和确定序列,并发送所述批次到执行研磨的工具(即,工艺中的下一个步骤)。该序列自己重复,直到制作完成。
所述控制机构232被配置为基于多个用户定义的目标优化非线性装配线200的产量。用户定义的目标的示例包括通过非线性装配线的每个封装体批次的平均加工时间、通过非线性装配线的优先封装体批次的子集的平均加工时间、每个加工工具在时间效率或功率效率方面的使用效率等。根据用户定义的目标,控制机制232可以确定最佳资源分配方案。所述最佳资源分配方案可以考虑各种因素,包括非线性装配线的当前状况,例如在制造中的封装体批次的数量、在制造中的封装体类型、装配线中各种加工工具的可用性、每个加工步骤所需的时间等。用户定义的目标和最佳资源分配方案可以由操作者手动输入,可以由存储在控制机构232的存储器中的软件来实现,或者可以由并入控制机构232的一次性可编程硬件来实现。
根据一个实施例,所述非线性封装体装配线200被配置为使用封装衬底面板对制造中的每个封装体批次执行并行加工。根据这项技术,一种标准尺寸的面板可以用作用于封装体形成的衬底。这种标准尺寸的面板通过非线性封装体装配线200。每个标准尺寸的面板包括多个封装位点。所述非线性装配线中的每个加工工具与面板型式兼容,使得加工工具可以装载面板,在所述面板的每个封装位点上执行它们各自的封装体加工步骤(引线接合、注射成型、金属蚀刻等),并在加工完成时使面板可用于传输。面板可以非常大,因此可以容纳大量的封装体。例如,根据一个实施例,面板是24英寸×18英寸。其它尺寸也是可能的,并且非线性封装体装配线200可以被配置为容纳两种或更多种不同尺寸的面板。所述面板可以包括电绝缘材料、导电材料或两者。根据一个实施例,所述面板包括铝层、聚合物层、铜层。这些面板的示例包括标准PCB制作面板。

参考图12B,结构化铜层1208在所述薄铜层之上形成在封装衬底面板上。结构化铜层1028可以通过掩模、电镀和蚀刻步骤形成。铜层被结构化成包括裸片焊盘1210和接合焊盘1212。根据一个实施例,结构化铜层的裸片焊盘1210比邻近的接合焊盘1212厚。

参考图13A,在裸片1214和接合焊盘1212之间形成电连接1216(即第一级互连)。这可以根据各种技术(包括引线接合、夹附接或两者的混合)中的任何一种来完成。在非常大尺寸的面板、例如18英寸×24英寸或更大的情况下,引线接合机可能没有足够大的工作区域来完成面板上每个封装体的引线接合。在这种情况下,引线接合可以通过对面板上的一半的封装位点执行引线接合、旋转面板、然后对面板上的另一半的封装位点执行引线接合来完成。
参考图13B,执行包覆成型工艺。根据这个工艺,裸片1214和电连接1216被电绝缘的模制化合物1218、例如热固性塑料包封。可以使用压缩成型或注射成型技术。

参考图15A,可焊接的贵金属层1222形成在结构化铜层上。根据一个实施例,可焊接的贵金属层1222通过非电式镀覆形成。非电式镀覆可以是诸如Sn或SnAG的锡基镀覆。所述镀覆形成在金属层1208的暴露的铜部分上、具体地是形成在裸片焊盘1210和接合焊盘1212的下侧以及接合焊盘1212的设置在凹槽1120内的内侧上。
参考图15B,执行完全的封装体分离工艺。所述封装体沿着凹槽分离。例如,这可以通过刀片切割来完成。
上述实施例中的部分切割/分离工艺和非电式镀覆工艺使得能够使用非线性封装体装配线200生产VQFN类型封装体。在封装衬底面板1200已经通过图14A的步骤去除之后,裸片焊盘1210和接合焊盘1212完全或部分地嵌入在模制化合物1218内。需要进一步加工,以使这些第二级互连点可焊接并且符合VQFN类型封装体的引线设计。通过形成延伸穿过接合焊盘1212的凹槽1220,暴露出接合焊盘1212的垂直于封装体的下侧的侧面。这些侧面被电镀,以在封装体的角部处形成封装体级端子。此外,裸片焊盘1210的下侧被电镀,以形成与裸片1214的下侧连接的连接端子。
参考图16-18,示出了根据另一个实施例的VQFN类型封装体形成工艺的剖视图。VQFN类型封装体可以使用非线性封装体装配线200形成。

参考图16B,第二级金属化层1608形成在铜层1606上。例如,第二级金属化层1608可以通过溅射、电镀和蚀刻步骤形成。第二级金属化层1608和铜层1606都被结构化,以形成裸片焊盘1610和多个接合焊盘1612。根据一个实施例,裸片焊盘1610比相邻的接合焊盘1612厚。例如,铜层1606和第二级金属化层1608可以通过掩模、电镀和蚀刻步骤被结构化。
参考图16C,裸片1614附接到裸片焊盘1610。这可以根据各种技术(包括焊接、烧结、胶合、压力接合等)中的任何一种来完成。
参考图17A,在裸片1614与接合焊盘1612之间形成电连接1616、即第一级互连。这可以根据各种技术(包括引线接合、夹附接或两者的混合)中的任何一种来完成。在非常大尺寸的面板、例如18英寸×24英寸或更大的情况下,所述引线接合机可能没有足够大的工作区域来完成面板上的每个封装体的引线接合。在这种情况下,引线接合可以通过对面板上的一半的封装位点执行引线接合、旋转面板、然后对面板上的另一半的封装位点执行引线接合来完成。
参考图17B,执行包覆成型工艺。根据该工艺,裸片1614和电连接1616被电绝缘的模制化合物1618包封。可以使用压缩成型或注射成型技术。
参考图17C,去除铝板1602。例如,这可以通过湿化学蚀刻来完成。
参考图18,去除聚合物层1604。例如,这可以通过湿化学蚀刻来完成。这样,裸片焊盘1610和接合焊盘1612嵌入在模制化合物1618中,但是在装置的下侧可以接近。可以例如通过非电式镀覆或印刷将最终涂层施加到裸片焊盘1610和接合焊盘1612。这样,可以获得一个完成的封装装置。
参考图19,示出了根据另一实施例的VQFN类型封装体。在该实施例中,除了以下之外,执行与参照图16-18所述相同的加工步骤。铜层1606选择得更厚些,例如35μm或更大。此外,铜层1606和第二级金属化层1608在图16和17中描述的裸片附接、引线接合和成型步骤之前未被结构化。相反,铜层1606和第二级金属化层1608在去除铝板1602和聚合物层1604之后被结构化。以这种方式,所述装置可以被配置成使得结构化金属层(即,裸片焊盘1610和接合焊盘1612)从模制化合物露出,如图19所示。
