Description

BVA中介结构
有关申请的交叉引用
本申请要求对提交于2012年8月3日的第61/679,653号美国临时申请的提交日的权益,其公开内容通过引用而结合于此。
技术领域
本申请涉及:一种中介结构(interposer),比如可以结合到可以包括未封装的(unpackaged)半导体裸片或封装的(packaged)半导体裸片的微电子组件中的中介结构;以及用于制作这样的中介结构的方法。具体而言,这里描述一种中介结构以及制作一种中介结构的方法,该中介结构结合有键合过孔(via)阵列,例如具有在包封体(encapsulation),比如模制的包封体的主表面未覆盖的末端的竖直地延伸接线键合阵列。
背景技术
微电子器件,比如半导体芯片,通常需要至其它电子部件的许多输入和输出连接。半导体芯片或其它类似的(comparable)器件的输入和输出接触,通常被布置为基本上覆盖器件表面的网格状图案(grid-like pattern)(常称为“面积阵列(area array)”),或者可以被布置为与器件正表面的每个边界平行且相邻地延伸的细长的行,或者被布置在正表面的中心。通常,器件,比如芯片,必须被物理地装配在衬底上,比如印刷电路板上,并且该器件的接触必须电连接到电路板的电传导特征。
半导体芯片通常被设置在封装体(package)中,封装体有助于在制造期间、以及在将芯片装配到外部衬底比如电路板或其它电路面板上期间,操纵半导体芯片。例如,许多半导体芯片被设置在适合用于表面装配的封装体中。该一般类型的许多封装体已经被提出用于各种应用。最常见地,这样的封装体包括常称为“芯片载体”的电介质元件,该电介质元件具有在电介质上形成为镀制或蚀刻的金属结构的端子。这些端子通常通过特征连接到芯片本身的接触,该特征比如是沿着芯片载体本身延伸的细迹线、以及在芯片的接触与端子或迹线之间延伸的细引线或者接线。在表面装配操作中,封装体被放置到电路板上,从而封装体上的每个端子与电路板上的对应接触焊盘对准。在端子与接触焊盘之间提供焊料或者其它键合材料。可以通过加热组件以便使焊料熔化或者“回流”、或者以别的方式来激活焊接材料,来将封装体永久地键合到适当的位置。
许多封装体包括焊球形式的焊料物质,其附着到封装体的端子、直径通常为约0.1mm和约0.8mm(5和30密尔)。具有从其底表面突出的焊球阵列的封装体常称为焊球网格阵列或者“BGA”封装体。称为焊区(land)网格阵列或“LGA”封装体的其它封装体,通过由焊料形成的薄层或者焊区而被固着到衬底。这一类型的封装体可以很紧凑。常称为“芯片比例封装体(chip scale package)”的特定封装体,占用的电路板面积与在该封装体中结合的器件面积相等、或者仅略微地大于该器件面积。其优点在于:它减少了组件的总尺寸,并且允许在衬底上的各种器件之间使用短互连,这又限制在器件之间的信号传播时间,因此有助于组件在高速操作。
可以提供中介结构,作为如下互连元件:其具有接触;并且其顶表面和底表面,在其顶表面或底表面中的一个处,与一个或者多个封装或者未封装的半导体管芯电连接,并且在其顶表面或底表面中的另一处,与另一部件电连接。该另一部件在一些情况下可以是封装体衬底,该封装体衬底又可以与又一部件电连接,该又一可以是电路面板或者可以包括电路面板。
尽管有本领域中有所有以上描述的进展,但是仍然期望对中介结构和制作中介结构的方法进行进一步的改进。

具体实施方式
现在参照各附图,其中相似标号用来指示相似特征,在图1中示出根据本发明的一个实施例的微电子组件100。图1的实施例是包括中介结构10的微电子组件,中介结构具有第一和第二相对朝向的侧144、114,例如顶表面和底表面,在其处分别设置有第一和第二接触46、16,用于分别与微电子组件的第一和第二部件电连接。这里描述的部件,比如中介结构、衬底、电路面板、微电子元件等在其外表面处具有电介质结构。因而,如在本公开中所用,关于电传导元件“在”部件的电介质结构的表面的陈述,指示在部件未与任何其它元件组装时,电传导元件可用于,与在与部件的表面垂直的方向上从部件外部朝着部件的表面移动的理论点接触。因此,在部件表面的端子或其它传导元件可以从这样的表面突出;可以与这样的表面齐平;或者可以相对于这样的表面而在部件中的孔或者下陷中凹陷。
如图1中所示,第一部件例如可以是在其上具有有源电路元件的部件,该有源电路元件比如是微电子元件的部件或者其它部件。微电子元件可以是封装或者未封装的半导体裸片,半导体裸片具有朝向中介结构10的第一侧144的面13,并且被封装或者未被封装为连接到中介结构的第一接触46。如图1中进一步所示,中介结构的第二接触16与组件的另一部件的对应接触电连接,另一部件可以是如图1中所示示例中的封装体衬底20。通过接线键合32,提供在第一与第二接触46、16之间的电连接,接线键合相互分离,并且在第一和第二相对朝向的侧144、114之间在中介结构的厚度方向上延伸。
作为图1中所示布置的备选或者除了该布置之外,第二接触16中的一些或者所有可以与具有与中介结构的第二侧114相向的表面的第二未封装或者封装的半导体裸片连接。
与中介结构10互连的封装体衬底20或另一部件又可以装配到电路面板50的接触52,如图1中所示。
图2图示根据又一示例的微电子组件102,其中第一和第二微电子元件12、52可以通过在中介结构11的第一侧144的第一接触46与中介结构11互连。可以是封装或者未封装的半导体裸片,可以通过在中介结构上提供的传导结构,比如在其上的迹线54,相互电连接,该传导结构可以在与中介结构的第一和第二侧144、114平行的方向上延伸。
参照图3,示出截面图,截面图进一步示出可以结合在比如图1或者图2中所示微电子组件中的中介结构10;并且图4是朝向中介结构的包封体19的顶表面44或者备选地朝向包封体19的底表面14查看的对应平面图。如图3和4中所见,可以使第一和第二接触46、16在与顶表面或者底表面44、14平行的横向方向上延伸超出相应接线键合32的边界表面37,如在接触46A和16A的情况下所见。通常由电介质材料制成的绝缘包封体19可以通过向模具中注入包封体剂材料来设置,该模具至少部分地包围如下结构,该结构具有键合到其一个或者多个表面的接线键合32,在这一情况下,如这里所用,包封体是“模制的包封体”。如例如在共同地拥有的第13/462,158、13/404,408、13/404,458、13/563,085、13/477,532和13/405,125号美国专利申请中所描述,接线键合32可以通过将接线键合到一个或者多个表面,比如接触的表面、或者片例如金属片的表面,来形成。如图3中最佳地所示,在一些情况下,迹线54、54A可以覆盖在包封体19的相对朝向的顶表面和底表面44、14中的一个或二者,或者可以嵌入于覆盖在包封体的这样的表面中的一个或两者的一个或者多个电介质层内,例如如图20中进一步所见。再次参照图2,包括在一些情况下可以如图所示竖直地堆叠和电互连的多个半导体裸片的组件,可以通过第一接触46与中介结构11电互连,并且还可以通过迹线来与微电子组件的另一裸片12或者封装的裸片电互连。
再次参照图3,通常通过将金属接线在一个或者多个表面的不同位置处键合到一个或者多个表面、来形成金属键合,来形成在包封体19的第一与第二表面44和14之间在延伸经过包封体19的方向上提供电互连的接线键合32,上述不同位置可以是阵列的位置,并且可以是在以下布置的金属层的表面。每个接线键合具有限定接线键合的一端的第一末端33以及限定与第一端相对的第二端的第二末端39。接线键合通常具有在每个接线键合的第一与第二末端之间延伸的圆柱形柱身以及在第一与第二末端之间的方向上延伸的边界表面37。
在具体示例中,键合工具可以将金属接线键合到分层结构的暴露表面,该分层结构包括未图案化或者图案化的金属片,并且可以在其上包括一个或者多个表面末层(finish)金属层。因此,在一个示例中,接线键合可以形成于具有铝、铜或者其合金等金属层的基部上,并且抛光层在一个示例中可以包括“ENIG”表面末层,比如通过无电镀沉积而在基部金属上沉积的镍层、接续的通过浸没工艺而在镍层上沉积的金层。在另一示例中,基部金属层可以具有“ENEPIG”表面末层,比如可以是在基部金属上沉积的无电镀沉积的镍层、接续的在其上沉积的无电镀沉积的钯层、和接续的通过浸没工艺在钯上沉积的金层的组合。
可以通过如在前述共同地拥有和结合的美国专利申请中的一份或者多份中所描述的技术、来将金属接线键合到表面,来形成接线键合。如这里所用,接线键合的“基部”34意味着接线键合的除了接线键合的通常为圆柱形的柱身之外的部分,该部分得自将金属接线的这样的部分键合到表面。基部34可以通过如下方式形成:将金属接线球形键合到表面,比如通过在接线的顶端加热接线以形成熔化的金属球、并且使表面与该球接触以形成球形键合以便形成接线的球根状部分作为基部34,例如如图3中所示。在这样的示例中,在接线键合的基部通过球形键合而形成的情况下,基部可以具有与球或者球的部分相似的形状。具有通过球形键合而形成的基部的接线键合可以具有如例如在通过引用而将公开内容结合于此的第13/462,158号美国专利申请中所描述的形状和形成方法。
备选地,如图5、6、7或者8中所见,可以通过其它技术比如针脚式键合或者楔形键合来形成基部35,其中接线的边界表面的部分键合到表面比如接触16、46。在这样的布置中,基部35可以具有以明显的角度(例如15至90度)从柱身延伸离开的、有些平坦化的圆柱形形状。具有通过针脚式或楔形键合而形成的基部的接线键合,可以具有大体上如图5、6、7和8中所见形状,并且可以如例如在通过引用而将公开内容结合于此的第13/404,408、13/404,458、13/405,125号美国专利申请中所描述而形成。接线键合的向上延伸柱身部分33无需相对于键合的基部35竖直地延伸,而是实际上可以以明显的角度(例如15至90度)从其延伸。这一方式形成的接线键合的具体示例可以如在这些结合的申请中所描述。
在示出球形键合到表面的基部的图9和图10的示例中,顶端38和38A可以随着它从接线键合的圆柱形柱身31延伸而变细。具体而言,如图9中所示,顶端38可以距离基部34更远而更窄。如图10中所示,顶端38A可以更远地从基部34的竖直柱身31弯曲离开。如图10中进一步所示,距离基部34甚至更远,然后顶端38A可以与顶端38相似地变细。
如图11和图12中所示,接线键合的顶端41、41A可以具有特定形状。在图11的示例中,顶端41可以从接线键合的圆柱形柱身31延伸,并且可以在一个维度中变细。在这样的示例中,顶端41可以在一个维度中变平坦,这可以有助于键合到另一平坦表面。在图12的示例中,顶端41A可以在多于一个维度中变细成更窄的轮廓。在这样的情况下,顶端41A可以形状为平截头圆锥体(frusto-conical)或者可以具有平坦化的平截头圆锥体轮廓。
在一些示例中,在通过针脚式键合、楔形键合或者球形键合中的任何键合来形成基部的情况下,接线键合柱身的与基部相邻的部分可以在不与表面正交的方向上从基部延伸离开,即,使得柱身的该部分在横向方向上从表面延伸离开。
经常地,在切断接线以限定末端之前或之后,通过在接线的末端位置球形焊接或者针脚式或楔形键合接线,来将将金属接线的末端键合到表面。然而,也存在用于在金属接线的除了上述位置之外的位置处将接线键合到表面的技术。例如可以将接线的远离接线末端的部分针脚式键合到表面,同时接线从键合的部分延伸离开、朝向每端延伸。
可以观察到,金属接线在其中具有这样的金属晶粒,其可以在接线的长度方向上伸长,即在相对于接线的大体上圆柱形柱身的直径横向的方向上伸长。在一些示例中,接线可以由金、铝、铜或者铜合金等等制成。在一些情况下,如图8中所见,接线可以包括基础金属的芯、以及与初级金属不同的金属比如例如钯的表面末层,如例如在通过引用而结合于此的美国申请13/404,408和13/404,458中所描述。
如图13中进一步所示,包封体可以在与接线键合的端36相邻的位置处,从其主表面44向下地凹陷,以便提供键合金属可以与接线键合的暴露端接触的更大表面积。备选地或者附加地,接线键合的端36可以延伸到在包封体的表面44上方的高度H。在这样的示例中,包封体可以凹陷或者可以平坦,其中接线键合在表面44的高度以上延伸,图14图示又一示例,如在结合的第13/462,158号申请中所描述,其中包围接线的边界表面的材料78从包封体19的主表面44凹陷以提供沟槽64,在该沟槽中,传导键合材料或者键合金属可以在对中介结构的接线键合进行接合时,即与另一部件的对应电传导特征电连接时,流动。
图15进一步图示可以通过减薄中介结构的后续步骤而形成的中介结构,该步骤比如是在形成包封体19之后被应用于包封体19的表面的例如研磨、磨平或者抛光。在这样的情况下,可以在减薄工艺期间去除接线键合的基部。可以执行这样的技术例如用于去除接线键合的基部,比如在接线键合的相邻基部之间的间距可能比后续的对于接线键合的在中介结构相邻表面14之侧的末端的接合工艺所希望或者适合的间距更近的情况下。
图16图示另一示例,其中基部(例如通过球形键合而形成或者通过针脚式或楔形键合而形成的基部)可以附着到在包封体的表面14的传导元件55,其中传导元件55可以是从接线键合所键合到的金属层的剩余的部分。在这样的情况下,在形成接线键合32之后,可以随后将金属层图案化,例如在形成包封体19之后。这样的用于随后将金属层图案化以形成传导元件55的处理,可以如例如在结合的第13/462,158号申请中所描述。传导元件55可以是中介结构的接触16或者接触46,或者可以是接触16或者接触46耦合到的内部结构,比如关于图18-图20所进一步描述的。
图17图示具体示例,其中接线键合的基部34的至少部分在包封体的主表面14被暴露,作为中介结构的接触,例如其第一或者第二接触。
图18-图20图示又一示例,其中还可以额外地形成具有一个或者多个电介质层的再分布结构21,该再分布结构21在中介结构的第一或者第二侧144、114处覆盖在包封体的主表面44、14中的一个或者多个上面,其中在包封体的这样的表面以上暴露这样的电介质层的表面。该一个或者多个电介质层可以承载可以包括一个或者多个电传导再分布层的电传导结构。包括在与包封体的表面44、14平行的方向上延伸的迹线54的再分布结构21,可以由延伸经过电介质层中的一个或者多个的过孔23内部地电连接。因此,中介结构的接触46可以通过再分布结构21而电连接到接线键合32,并且可以至少由与包封体表面44和/或14平行延伸的接线而经过上述再分布结构连接。图18图示其中包括传导结构和一个或多个电介质层的再分布层设置于在包封体的表面44以上的侧面144的示例。图19图示其中包括传导结构和一个或多个电介质层的再分布结构设置于在表面14以上的侧面114的示例。图20图示其中再分布结构21设置于相应表面44、14中的每一个表面以上的示例。
图21和图22是进一步图示中介结构210的具体示例的截面图和对应平面图,其中接线键合中的至少一些的第二末端239从它们的延伸相应第一末端233、在与包封体的表面44平行的横向方向上偏移,它们从该相应第一末端延伸、并且通过相应的接线键合柱身直接地连接。如图21和图22中进一步所见,接线键合的第二末端可以在其相邻接线键合之间按最小节距例如节距P2间隔,该最小节距与在相邻接线键合232的第一末端之间的原最小节距P1不同。结合的第13/462,158号申请提供了用于制作在包封体的顶表面和底表面具有不同布置并且在包封体表面具有不同最小节距的接线键合的进一步描述,比如其中关于图18和图19所描述。
中介结构或者结合该中介结构的微电子组件的以上描述的实施例可以进一步结合到系统中,比如相对于结合的第13/462,158号申请的图23示出和描述的系统中。
图23和图24提供根据以上描述的示例中的任何示例的中介结构的变化的截面图和俯视图,其中中介结构310具有从中介结构的第一侧144延伸到第二侧114的贯穿开口65。如图24中所示,接线键合32的末端36(或者基部34)可以在第一和第二侧144、114被暴露,或者可以与在中介结构上设置的其它传导结构比如在其上的迹线54、54A电连接,其它传导结构可以在与中介结构310的相应第一和第二侧144、114中的或者二者平行的方向上延伸。如在以上描述的示例(图18-图20)中,迹线54可以覆盖在包封体的相对朝向的表面14、44中的一个或者二者上面,并且可以是再分布结构的部分,或者可以关于表面14、44中的一个或两者来嵌入。
图25是图示微电子组件103的分解图,其中第一和第二微电子封装体71、81可以被组装,并且通过中介结构310相互电互连。微电子包封体71的衬底72可以具有与中介结构310的第一侧144相向的第一表面73。在中介结构的侧114的接触16可以与在电介质元件例如微电子封装体81的衬底82的表面83的对应接触86对准;并且比如通过在接触86或者16的表面处的键合材料或者键合金属例如金、锡、铟、焊料或者共晶材料,来接合到对应接触86。中介结构310的接触46可以与微电子包封体71的对应端子56对准,该对应端子56比如可以例如设置在衬底72的第一表面73处;并且通过附着到端子56的键合材料,比如可以被提供为接合元件58的键合材料,来接合到对应端子56。
如图25以及图26中所示,第一微电子元件75,如图所示“倒装芯片”,可以放置于衬底72的与其第一表面73相对的第二相对朝向表面74。在如图所示倒装芯片布置中,第一微电子元件75具有在微电子元件75的第一元件表面处的用于与在第二表面74的相应接触76连接的多个接触77。在如图25和图26中进一步所示备选“面朝上”布置中,第一微电子元件75可以具有在微电子元件75的与第一元件表面相对的相对朝向第二元件表面处的一个或者多个键合焊盘78,用于通过一个或者多个相应键合接线90(在图25和图26中示出为虚线)来与在第二表面74的相应接触76电互连。在这样的布置中,接触76中的至少一些可以与在衬底72的第一表面73处的接触56中的至少一些电连接。以这一方式,第一微电子元件75可以与接触56中的至少一些电互连。
仍然参照图25和图26,第二微电子封装体81可以包括按“倒装芯片”配置的衬底82和第二微电子元件85,其中第二微电子元件放置于衬底82的第一表面83上并且与第一表面83电互连。如图所示,第二微电子元件85可以具有在微电子元件85的第一元件表面处的一个或者多个凸块87,用于与在第一表面83的相应接触86连接。在备选布置中,第二微电子元件85可以具有在微电子元件85的与第一元件表面相对的相对朝向第二元件表面处的一个或者多个键合焊盘88,用于通过一个或者多个相应键合接线95(在图23中表示为虚线)来与在第一表面83处的相应接触86电互连。通过这样的布置,第二微电子元件85可以与在衬底82的与其第一表面83相对的第二相对朝向表面84处的接触57电互连。
在衬底82在固定定位时,中介结构310然后可以被放置到衬底82上并且接合到衬底82,其中中介结构310的贯穿开口65包围第二微电子元件85。备选地,在中介结构310在固定定位时,衬底82可以与中介结构310紧靠地放置,并且接合到中介结构310,其中第二微电子元件85放置于中介结构310的贯穿开口65内。在以上任一布置中,衬底82的第一表面83可以与中介结构310的第二侧114紧靠地齐平地放置。如对照图23和图24所示,第二微电子元件85可以被减薄到这样的厚度,使得在第二微电子元件85的第一表面83与中介结构310的第二侧114紧靠地齐平地放置时,第二微电子元件85的任何部分都不在中介结构310的第一侧144以上。在微电子组件103的备选布置(未示出)中,第二微电子元件85可以未被减薄,而代之以可以具有如下部分,该部分落在中介结构310的第一侧44以上、并且适配在接合元件58之间、并且上至恰在第一微电子封装体71的衬底72的第一表面73以下的点。在这些布置中的任何布置中,包括第一和第二微电子元件75、85的第一和第二微电子封装体71、81可以通过中介结构310来相互电互连。
第二微电子封装体81的衬底82的第一表面83可以朝向中介结构310的第二侧14。中介结构310可以通过在第一表面83处的接触86与中介结构310的相应接线键合32的基部34之间的连接,来与第二微电子封装体81电互连,其中该基部34可以覆盖在相应接触86上面并且与相应接触86互连。备选地,中介结构310可以包括从接线键合32的相应基部34偏移的接触(未示出),该基部34可以被定位成朝向在衬底82的第一表面83的相应接触86、并且比如通过键合金属来与相应接触86接合,比如以上针对按“倒装芯片”装配布置的连接所描述的。
第二微电子封装体81可以包括在衬底82的第二表面84的端子59,该端子59通过传导连接(未示出)电互连通过衬底82。可以是焊球以及其它可能结构的接合元件57,可以接合到第二微电子封装体81的端子59,从而第二微电子封装体81可以与其它器件或者子组件电互连,并且从而微电子组件103可以与其它器件或者子组件电互连。
图27和图28图示根据以上描述的示例中的任何示例的微电子组件的备选布置。具体而言,图27是在微电子组件104的中介结构310的贯穿开口65内容纳的第二微电子封装体121的截面图,而图28是平面图。在所示示例中,微电子组件104可以包括微电子组件103的所有特征而,不同之处在于衬底81未形成组件104的部分。
如图所示,可以在中介结构310的第二侧114形成覆盖在包封体的主表面14上面的再分布结构121。再分布结构121可以具有根据图18-图20的示例的结构。如图所示,再分布结构121还可以具有迹线54,该迹线54嵌入在再分布结构121的电介质层内、用于电连接第二微电子元件85与中介结构310。如图所示,迹线54可以在与中介结构310的第二侧114平行的方向上延伸,并且在为“倒装芯片”配置的情况下,将在微电子元件85的第一元件表面处的凸块87电连接到接线键合32的基部34。在一些布置中,接触或者其它传导结构可以覆盖在接线键合32的基部34或者第二微电子元件85的凸块87上面,并且连接到基部34或者凸块87,其可以通过覆盖在再分布结构121的电介质层上面的迹线54连接。
如进一步所示,包封体191可以被添加到贯穿开口65,包封体可以填充贯穿开口65以相对于中介结构310固定第二微电子元件85的定位,如这里进一步描述的。包封体192可以被添加为包围中介结构310以提供用于中介结构310的附加的支撑和刚性。如图27中进一步所示,在一些布置中,第二微电子元件85可以电连接到部件或者接合元件,该部件或者接合元件在中介结构310的第二侧114处通过再分布结构121的过孔23电连接,过孔23从第二微电子元件85的凸块87延伸并且电连接到凸块87。
