要求保护本国优先权
本申请要求保护2012年12月11日提交的美国临时申请No. 61/735,926的权益,通过引用将该申请合并于此。
技术领域
本发明总体上涉及半导体器件,并且更特别地涉及半导体器件以及形成具有垂直互连单元的扇出式封装(fan-out package)或层叠封装(package-on-package)半导体器件的方法。
背景技术
半导体器件常见于现代电子产品中。半导体器件在电气部件的数目和密度方面变化。分立的半导体器件通常包含一种类型的电气部件,例如发光二极管(LED)、小型信号晶体管、电阻器、电容器、电感器以及功率金属氧化物半导体场效应晶体管(MOSFET)。集成半导体器件典型地包含几百到几百万个电气部件。集成半导体器件的示例包括微控制器、微处理器、电荷耦合器件(CCD)、太阳能电池、以及数字微镜器件(DMD)。
半导体器件执行许多种功能,诸如信号处理、高速计算、发射和接收电磁信号、控制电子器件、将太阳光变换成电、以及为电视显示创建视觉投影。半导体器件见于娱乐、通信、功率转换、网络、计算机以及消费者产品的领域中。半导体器件还见于军事应用、飞机制造业、汽车、工业控制器以及办公设备中。
半导体器件利用了半导体材料的电气性质。半导体材料的结构允许通过施加电场或基底电流或者通过掺杂工艺来操纵其电导率。掺杂将杂质引入到半导体材料中以便操纵和控制半导体器件的电导率。
半导体器件包含有源和无源电气结构。包括双极型和场效应晶体管的有源结构控制电流的流动。通过改变掺杂级以及电场或基底电流的施加,晶体管提升或者约束电流的流动。包括电阻器、电容器和电感器的无源结构创建了执行各种各样的电气功能所必需的电压和电流之间的关系。无源和有源结构被电连接以形成电路,该电路使半导体器件能够执行高速操作和其他有用功能。
通常使用两个复杂制造工艺(即前端制造和后端制造)来制造半导体器件,该前端制造和后端制造中的每一个都潜在地包括几百个步骤。前端制造包括将多个管芯形成在半导体晶片的表面上。每个半导体管芯通常相同且包含通过电连接有源和无源部件而形成的电路。后端制造包括从完成的晶片单切(singulate)个体半导体管芯以及封装该管芯以提供结构支撑和环境隔离。如这里所使用的术语“半导体管芯”指代该词语的单数和复数形式二者,并且相应地可以指代单个半导体器件和多个半导体器件二者。
半导体制造的一个目标是生产更小半导体器件。更小器件通常耗费更少功率,具有更高性能,并可以被更高效地生产。此外,更小半导体器件具有更小的覆盖区,这对于更小的最终产品来说是期望的。可以通过得到具有更小、更高密度的有源和无源部件的半导体管芯的前端工艺中的改进来实现更小的半导体管芯尺寸。后端工艺可以通过电互连以及封装材料中的改进来得到具有更小覆盖区的半导体器件封装。
对于蜂窝或智能电话产业中的封装来说,减小的封装轮廓特别重要。三维(3D)扇出式半导体封装和外部器件之间的电互连利用各种互连类型,诸如通过再分布层(RDL)的穿透式硅通孔(TSV)和穿孔式通孔(THV)互连。RDL用作包括具有封装输入/输出(I/O)焊盘的电互连的封装内的电互连的中间层,所述封装输入/输出(I/O)焊盘提供从半导体封装内的半导体管芯到半导体封装外的点的电连接。RDL可以被形成在半导体封装之内的半导体管芯的前表面和后表面二者上并且具有薄晶片和面板处理能力。然而,将多个RDL形成在半导体管芯的前表面和后表面上可能需要与定制接合材料的临时接合(这可能需要更高耐热性)并可以是一种用于针对半导体封装进行电互连从而产生更高制造成本的缓慢且昂贵方法。另外,RDL的薄堆叠包括结构限制和降低的设计灵活性。例如,RDL提供了有限的封装处理机械强度和可靠性。RDL缺少模块性且难以在半导体封装的特定区域中形成。
发明内容
存在对在减少RDL应用的情况下形成低轮廓(low profile)3D半导体封装结构的需要。相应地,在一个实施例中,本发明是一种制作半导体器件的方法,其包括下述步骤:提供半导体管芯;沿着半导体管芯的外围区设置第一模块化互连结构;提供半导体部件,其包括在该半导体部件上形成的第二互连结构;以及将该半导体部件设置在半导体管芯上以使第二互连结构与第一模块化互连结构对准。
在另一实施例中,本发明是一种制作半导体器件的方法,其包括下述步骤:提供半导体管芯;以及沿着半导体管芯的第一和第二侧设置模块化互连结构。
在另一实施例中,本发明是一种半导体器件,其包括半导体管芯和在该半导体管芯的表面上形成的第一互连结构。沿着该半导体管芯的外围区并且与第一互连结构垂直地设置第二互连结构。

具体实施方式
在以下描述中的一个或多个实施例中参考附图来描述本发明,在附图中,相似的数字表示相同或类似的元件。尽管按照用于实现本发明目的的最佳模式来描述本发明,但是本领域技术人员将认识到,本发明意图覆盖如可被包括在如由如得到下面的公开和附图支持的所附权利要求及其等同物限定的本发明精神和范围内的替换、修改和等同物。
通常使用两个复杂制造工艺(前端制造和后端制造)来制造半导体器件。前端制造包括将多个管芯形成在半导体晶片的表面上。晶片上的每个管芯包含有源和无源电气部件,它们被电连接以便形成功能性电路。有源电气部件(诸如晶体管和二极管)具有控制电流的流动的能力。无源电气部件(诸如电容器、电感器和电阻器)创建执行电路功能所必需的电压和电流之间的关系。
通过一系列工艺步骤(包括掺杂、沉积、光刻、蚀刻以及平坦化)将无源和有源部件形成在半导体晶片的表面上。掺杂通过诸如离子注入或热扩散之类的技术将杂质引入到半导体材料中。掺杂工艺通过响应于电场或基底电流动态地改变半导体材料电导率来修改有源器件中半导体材料的电导率。晶体管包含如使晶体管能够在施加电场或基底电流时提升或约束电流的流动所必需的那样布置的改变掺杂的类型和程度的区。
有源和无源部件由具有不同电气性质的材料的层形成。可以通过各种各样的沉积技术来形成这些层,所述沉积技术部分地由所沉积的材料的类型来确定。例如,薄膜沉积可以包括化学气相沉积(CVD)、物理气相沉积(PVD)、电解电镀以及无电解镀工艺。每个层通常被图案化以便形成有源部件部分、无源部件部分或各部件之间的电连接部分。
后端制造指的是将完成的晶片切割或单切成个体半导体管芯并且然后为了结构支撑和环境隔离而封装该半导体管芯。为了单切半导体管芯,沿着被称为锯道或痕的晶片非功能区对晶片刻痕(score)并使其断裂。使用激光切割工具或锯片来单切晶片。在单切之后,将个体半导体管芯安装到包括用于与其他系统部件互连的接触焊盘或管脚的封装衬底。然后将在半导体管芯上形成的接触焊盘连接到封装内的接触焊盘。可以利用焊接凸块、柱形凸块(stud bump)、导电浆料或线接合来进行电连接。将密封剂或其他模制材料沉积在封装上以提供物理支撑和电隔离。然后将完成的封装插入到电气系统中并且使半导体器件的功能对其他系统部件来说可用。
图1图示具有芯片载体衬底或印刷电路板(PCB)52的电子器件50,在所述芯片载体衬底或印刷电路板(PCB)52的表面上安装有多个半导体封装。根据应用,电子器件50可以具有一种类型的半导体封装或多种类型的半导体封装。为了说明目的,在图1中示出不同类型的半导体封装。
电子器件50可以是独立的系统,其使用半导体封装来执行一个或多个电气功能。可替换地,电子器件50可以是更大系统的子部件。例如,电子器件50可以是蜂窝电话、个人数字助理(PDA)、数字视频摄像机(DVC)或其他电子通信设备的一部分。可替换地,电子器件50可以是图形卡、网络接口卡或可被插入到计算机中的其他信号处理卡。半导体封装可以包括微处理器、存储器、专用集成电路(ASIC)、逻辑电路、模拟电路、射频(RF)电路、分立器件、或者其他半导体管芯或电气部件。为了使产品被市场接受,小型化和重量减轻是根本的。可以减小半导体器件之间的距离来实现更高密度。
在图1中,PCB 52提供了用于在PCB上安装的半导体封装的结构支撑和电互连的一般衬底。使用蒸发、电解电镀、无电解镀、丝网印刷或其他适合的金属沉积工艺来在表面上或在PCB 52的层内形成导电信号迹线54。信号迹线54提供了半导体封装、所安装的部件以及其他外部系统部件中的每一个之间的电通信。迹线54还提供了向每一个半导体封装的电源连接和接地连接。
在一些实施例中,半导体器件具有两个封装级。第一级封装是一种用于将半导体管芯机械和电附着到中间载体的技术。第二级封装包括将中间载体机械和电附着到PCB。在其他实施例中,半导体器件可以仅具有第一级封装,在其中管芯直接机械和电安装到PCB。
为了说明的目的,在PCB 52上示出若干种类型的第一级封装,包括接合线封装56和倒装芯片58。另外,在PCB 52上示出安装了若干种类型的第二级封装,包括球栅阵列(BGA)60、凸块芯片载体(BCC)62、双列直插式封装(DIP)64、焊盘栅阵列(LGA, land gridarray)66、多芯片模块(MCM)68、四方扁平无引线封装(QFN)70以及四方扁平封装72。根据系统需求,被配置有第一和第二级封装方式的任何组合的半导体封装以及其他电子部件的任何组合可以被连接到PCB 52。在一些实施例中,电子器件50包括单个附着的半导体封装,而其他实施例要求多个互连封装。通过在单个衬底上组合一个或多个半导体封装,制造商可以将预制的部件合并到电子器件和系统中。因为半导体封装包括完善的功能,所以可以使用不太昂贵的部件和流线型制造工艺来制造电子器件。所得到的器件不太可能出现故障且在制造上不太昂贵,从而导致消费者的成本降低。

半导体晶片120经受作为质量控制工艺的一部分的电气测试和检查。人工目视检查和自动化光学系统被用来对半导体晶片120执行检查。可以在半导体晶片120的自动化光学分析中使用软件。目视检查方法可以采用诸如扫描电子显微镜、高强度或紫外光、或者金相显微镜之类的设备。针对结构特性(包括翘曲、厚度变化、表面颗粒、不规则性、裂缝、脱层和褪色)来检查半导体晶片120。
半导体管芯124内的有源和无源部件经受对电气性能和电路功能的晶片级处的测试。使用探头或其他测试器件来针对功能和电气参数测试每个半导体管芯124。探头被用来进行与每个半导体管芯124上的节点或接触焊盘132的电接触并向接触焊盘提供电刺激。半导体管芯124对该电刺激做出反应,测量该反应并且将其与预期反应进行比较以测试半导体管芯的功能。电气测试可以包括电路功能、引线完整性、电阻率、连续性、可靠性、结深度、静电放电(ESD)、射频(RF)性能、驱动电流、阈值电流、泄漏电流、以及部件类型所专用的操作参数。半导体晶片120的检查和电气测试使通过的半导体管芯124能够被指定为供在半导体封装中使用的成品管芯(KGD, known good die)。

载体140可以是具有针对多个半导体管芯124的容量的圆形或矩形面板(大于300mm)。载体140可以具有比半导体晶片120的表面积更大的表面积。较大的载体降低了半导体封装的制造成本,因为可以在较大的载体上处理更多半导体管芯从而降低每单位的成本。针对所处理的载体或晶片的尺寸来设计和配置半导体封装和处理设备。
为了进一步降低制造成本,与半导体管芯124的尺寸或半导体晶片120的尺寸无关地选择载体140的尺寸。也就是说,载体140具有固定或标准化尺寸,它可以容纳从一个或多个半导体晶片120单切的各种尺寸半导体管芯124。在一个实施例中,载体140是直径为330mm的圆形。在另一实施例中,载体140是宽为560mm且长为600mm的矩形。半导体管芯124可以具有被放置在标准化载体140上的10mm×10mm的尺度。可替换地,半导体管芯124可以具有被放置在同一标准化载体140上的20mm×20mm的尺度。相应地,标准化载体140可以处理任何尺寸半导体管芯124,这允许后续半导体处理设备针对普通载体而标准化,即与管芯尺寸或引入的晶片尺寸无关。可以使用根据任何引入的晶片尺寸处理任何半导体管芯尺寸的处理工具、设备和材料清单的普通集合来为标准载体设计和配置半导体封装设备。普通或标准化载体140通过减少或消除对基于管芯尺寸或引入的晶片尺寸的专用半导体工艺线的需要来降低制造成本和资本风险。通过从所有半导体晶片中选择用于任何尺寸半导体管芯的预定载体尺寸,可以实施灵活的生产线。

图4l还示出从与图3a-3c类似的半导体晶片单切的半导体封装、半导体管芯或半导体部件230,其具有背表面252和有源表面254,该有源表面254包含被实施为根据管芯的电气设计和功能而在管芯内形成且电互连的介电层、导电层、无源器件和有源器件的模拟或数字电路。例如,该电路可以包括一个或多个晶体管、二极管、以及在有源表面254内形成以实施模拟电路或数字电路(诸如DSP、ASIC、存储器或其他信号处理电路)的其他电路元件。半导体管芯230还可以包含用于RF信号处理的IPD,诸如电感器、电容器和电阻器。与图3a-3c的半导体管芯124类似地,半导体管芯230在从半导体晶片单切之前或之后经受电气测试。
使用PVD、CVD、印刷、旋涂、喷涂、烧结、热氧化或其他适合的工艺将绝缘或钝化层255形成在半导体管芯230上。绝缘层255包含SiO2、Si3N4、SiON、Ta2O5、Al2O3或者具有类似绝缘和结构性质的其他材料的一个或多个层。通过LDA、蚀刻或者其他适合的工艺来去除绝缘层255的一部分以用于后续的电互连。

使用拾取和放置操作,将半导体管芯230安装到个体半导体封装227,其中有源表面254是朝向通孔216定向的并且凸块258延伸到通孔216中以接触互连单元600。如先前所讨论,可以在堆叠组装之前将凸块224预先形成在通孔216之内(图4m)。在一些应用中,半导体管芯230具有比半导体管芯124的宽度更大的宽度。在已经将半导体管芯230安装到半导体封装227之后,半导体管芯230可以位于半导体管芯124的覆盖区之外或者部分地位于该覆盖区之外。在一些实施例中,互连结构被形成在半导体管芯230的有源表面254上,并且凸块258被形成在互连结构的表面上。在其他实施例中,半导体管芯230不具有凸块258,并且半导体管芯230在互连单元600处通过在通孔216中预先形成的凸块224与个体半导体封装227连接,如图4m中所示。在另一实施例中,半导体管芯230在互连单元600处通过凸块258和互连结构的组合或者通过没有凸块258的互连结构与个体半导体封装227连接。凸块258的形成可以恰在将半导体管芯230安装到个体半导体封装227之前或期间进行。
在将半导体管芯230安装在个体半导体封装227上之前,将底部填充材料260、环氧树脂粘附材料、环氧化合物或模制材料设置在半导体封装227的覆盖区内的绝缘层210上,如图4n中所示。虚线261指示半导体管芯230的管芯附着区域。通过如在个体半导体封装227的覆盖区内的绝缘层210上设置的点的平衡位置来施加底部填充材料260。底部填充材料260在堆叠组装以及将半导体管芯230安装在个体半导体封装227上期间支撑半导体管芯230。可替换地或者与底部填充材料260相结合,将非导电浆料设置在绝缘层210上,以在堆叠组装以及将半导体管芯230安装在个体半导体封装227上期间提供附加支撑。底部填充材料260在安装期间以及在后续的回流工艺期间提供支撑。可选地,可以将底部填充材料260设置在半导体管芯230的有源表面254上。
在一些实施例中,凸块258形成设置在半导体管芯230的有源表面254上的互连结构的一部分以便促进半导体管芯230的重新布线,与互连结构190类似。凸块258可以从互连结构延伸以使得互连结构、凸块258、互连结构190和互连单元600组成从半导体封装227到半导体管芯230形成的L形互连。
在堆叠组装之后或期间,通过化学蚀刻、机械剥皮、CMP、机械研磨、热烘焙、UV光、激光扫描或湿法脱模来去除载体228。可以将可选的密封剂沉积在半导体封装227和半导体管芯230上。
图5示出在与载体228分离之后在半导体管芯230和凸块258安装在半导体管芯124上的情况下使用图4a-4n中所示的工艺形成的半导体封装300。在一些实施例中,半导体管芯230在半导体管芯124上横向偏移,以使得半导体管芯230设置在半导体管芯124的一部分上。互连单元600被设置在半导体封装300之内与互连结构190垂直,并垂直地延伸在互连结构190上。在一些实施例中,凸块258连同互连单元600的高度大于半导体管芯124的厚度。因此,在有源表面254和背表面128之间存在间隙。使绝缘层210介于有源表面254和背表面128之间的间隙中。可替换地,凸块258连同互连单元600的高度等于或小于半导体管芯124的厚度。半导体管芯230的有源表面254可以倚靠在背表面128之上的绝缘层210上,其中在有源表面254和背表面128之间不存在间隙。在背表面128和密封剂160上形成且介于有源表面254和背表面128之间的绝缘层210提供物理支撑,控制总体封装翘曲,并在环境上保护半导体管芯124免于外部元件和污染物。绝缘层210为半导体封装300提供结构支撑,平衡封装上的压力,并在后续的处理和工艺期间减小封装300的翘曲或破裂。
半导体封装300通过互连结构190、互连单元600和凸块258的组合来提供3D垂直电互连。利用减小的背侧RDL来形成垂直互连。互连结构190被形成在半导体管芯124的有源表面130上以及密封剂160上,其中互连结构190的一部分围绕半导体管芯124的外围。互连结构190包括形成扇出式互连结构的绝缘和导电层,并包括原本将被包括在背侧RDL或互连结构中的元件。互连单元600提供垂直互连以减小RDL层,并在没有与将完整的RDL层或多个RDL形成在半导体封装300的背侧上相关联的成本和更困难制造工艺的情况下提供部分背侧RDL。在半导体封装300内使用互连单元600提供了设计灵活性且减小了半导体封装300的高度。半导体封装300是低轮廓3D封装结构。
使用预制的模块化互连单元600在封装期间提供了附加的灵活性,因为可以在封装工艺的各种阶段处将互连单元600安装到载体140或半导体封装300。使用粘附剂安装互连单元600不需要在半导体封装300的封装期间将层形成在载体140上。互连单元600是能够设置在半导体封装(诸如半导体封装300)内或从其去除的模块化单元,而不像在半导体封装内形成的层那样。设置在半导体管芯124周围的互连单元600在减少RDL应用的情况下提供了垂直互连。围绕半导体管芯124形成的互连单元600在封装期间提供结构支撑并在施加密封剂160和外部半导体部件(诸如半导体管芯230)期间减小移位。在一些实施例中,从导电层256通过凸块258、互连单元600、导电层180、导电层184到凸块188制成沿垂直平面的连续垂直互连。在减小半导体封装300的高度的同时利用半导体封装300实现了真正的3D互连。作为垂直结构,互连单元600除了提供垂直电互连之外,还可以围绕半导体管芯124的侧部分或外围区形成边界、框架、缝隙或其他类似支撑结构。互连单元600减少了在封装内形成的RDL的数量。互连单元600在没有与在半导体封装中形成多个RDL相关联的成本、时间和其他制造约束的情况下提供部分背侧RDL。互连单元600在减小z方向封装高度的同时提供设计灵活性。
可以以与设置在半导体管芯124周围的互连单元600的布局或定向相匹配的定向将凸块258或外部器件(诸如半导体管芯230)的互连结构设置或形成在半导体管芯230上。将凸块258或半导体管芯230的互连结构与互连单元600的布局相匹配减少了制造材料和成本。将互连单元600与凸块258或半导体管芯230的互连结构相匹配提供了一致且可靠的3D垂直互连。在一些实施例中,互连结构190还与半导体管芯124周围的互连单元600的定向相匹配。
通过将互连单元600设置成与堆积(build-up)层和RDL相对来创建垂直互连提供了封装设计的增强灵活性。互连单元600不必设置在整个表面区域上,而是可以作为模块化单元设置在半导体封装300内的定制位置处,这对于其他互连结构来说难以完成。例如,将互连单元600设置在半导体管芯124的第一侧部分上而不是围绕半导体管芯124的第二侧部分可以释放半导体封装300内的宝贵空间并暴露围绕半导体管芯124的第二侧部分以用于附加的电气部件。可替换地,在期望增加的垂直互连密度的情况下,互连单元600可以完全包围半导体管芯124以得到密集却灵活的垂直互连。互连单元600在优化半导体封装300内的空间的同时节省了材料。

图6c示出在密封剂325之前且在将互连单元326安装到界面层310之后来自图6b的半导体封装的顶视图。在一些实施例中,互连单元326被设置在半导体管芯124的相对侧上。虚线261表示用于半导体管芯230的后续安装的管芯附着区域。
