Description
技术领域
本发明实施例涉及一种集成扇出型封装。
背景技术
由于各种电子组件(例如晶体管、二极管、电阻器、电容器等)的集成密度不断提升,因此,半导体工业快速成长。近年来,这种集成密度的提升,大多因为最小特征尺寸的持续缩小,因此可以将更多的组件集成在一定的区域中。相较于以前的封装体,这些较小的电子组件也仅需要使用较小面积的较小封装体。半导体组件中的一些较小型式的封装包括有四面扁平封装(quad flat packages,QFPs)、针栅数组(pin grid array,PGA)封装、球栅数组(ball grid array,BGA)封装等。
目前,集成扇出型封装由于其密度而趋于热门。如何减少集成扇出型封装的制造成本将成为重要的议题。

图1至图15为依照本发明一些实施例的一种集成扇出型封装的制造过程的各种阶段的剖面示意图。
请参照图1,提供载体C,载体C具有形成在其上的剥离层(de-bonding layer)DB与第一介电层102a,其中剥离层DB形成在载体C与第一介电层102a之间。在一些实施例中,载体C为玻璃基板,剥离层DB为形成在玻璃基板上的光热转换(light-to-heat conversion,LTHC)离形层,而第一介电层102a为形成在剥离层DB上的光敏聚苯恶唑(photosensitivepolybenzoxazole,PBO)层。在替代实施例中,剥离层DB也可以是在光固化过程中会降低其黏性的光固化离形膜(photo-curable release film),或者是在热固化过程中会降低其黏性的热固化离形膜(thermal curable release film)。而第一介电层102a也可以由其他的光敏或非光敏介电材料所制成。在一些实施例中,第一介电层102a可以是聚苯恶唑(PBO)层、聚酰亚胺(PI)层或其他合适的介电层。
请参照图2,通过例如物理气相沉积法在第一介电层102a上形成晶种层104。在一些实施例中,物理气相沉积法包括溅镀法、蒸镀法或任何其他合适方法。晶种层104可以是包括铜、铝、钛、上述合金或上述多层的金属晶种层。在一些实施例中,晶种层104包括第一金属层(例如钛层(未示出))以及位在第一金属层上的第二金属层(例如铜层(未示出))。
请参照图3,在形成晶种层104之后,在晶种层104上形成图案化光刻胶层106。图案化光刻胶层106具有多个开口,使得部分晶种层104外露于图案化光刻胶层106的开口。
请参照图4,进行例如电镀工艺以在部分晶种层104上形成第一重配置导电层102b、第一重配置导电层102c。具体来说,第一重配置导电层102b位在第一重配置导电层102c的两旁。第一重配置导电层102b、第一重配置导电层102c被电镀在外露于图案化光刻胶层106的开口的部分晶种层104上。在一些实施例中,第一重配置导电层102b、第一重配置导电层102c可以是金属层,其包括铜、铝、钛或其合金。
请参照图4与图5,在形成第一重配置导电层102b、第一重配置导电层102c之后,剥离图案化光刻胶层106,使得未被第一重配置导电层102b、第一重配置导电层102c所覆盖的部分晶种层104外露。
如图6所示,通过使用第一重配置导电层102b、第一重配置导电层102c当作掩膜,移除未被第一重配置导电层102b、第一重配置导电层102c所覆盖的部分晶种层104,以形成晶种层104a并暴露第一介电层102a的表面。也就是说,被第一重配置导电层102b、第一重配置导电层102c所覆盖的部分晶种层104未被蚀刻并且被留下以形成晶种层104a。第一重配置线路结构102包括第一介电层102a与其上的第一重配置导电层102b、第一重配置导电层102c。在全文中,晶种层的剩余部分104a可视为第一重配置导电层102b、第一重配置导电层102c的底部。在后续附图中,晶种层的剩余部分104a被视为第一重配置导电层102b、第一重配置导电层102c的一部分且不个别示出。
另一方面,如图6所示,虽然图6中仅示出一层第一介电层102a、一层第一重配置导电层102b以及一层第一重配置导电层102c,但本发明不以此为限。在替代实施例中,第一介电层102a与第一重配置导电层102b、第一重配置导电层102c的数量与配置可依产品的设计与需求来进行调整。在形成第一重配置线路结构102之后,另一个介电层可直接形成在第一重配置线路结构102上,然而,另一个介电层的图案化工艺可被省略。
请参照图7与图8,在第一重配置导电层102b上形成多个焊膏107。于焊膏107上分别安置多个导电柱110。接着,进行回焊工艺,焊膏107可经回焊以形成焊点108,且导电柱110可通过焊点108与第一重配置导电层102b接合。参照图7与图8,焊膏107的材料与导电柱110的材料不同。在一些实施例中,焊膏107的熔点小于导电柱110的熔点。在一些实施例中,焊膏107的材料可包括金属材料,其包括锡、银、铜或其合金。焊膏107的形成方法可例如是印刷法、喷涂法或其他合适的方法。导电柱110的材料包括金属,其包括铜或其他合适金属。在一些实施例中,导电柱110为预先制作的(pre-fabricated)且可由材料供货商所提供。
请参照图8,导电结构130包括第一部分与第二部分。第一部分可例如是焊点108,而第二部分可例如是导电柱110。焊点108的侧壁与导电柱110的侧壁具有不同轮廓。在一些实施例中,导电柱110具有直线型(straight)的侧壁,而焊点108具有锥形(tapered)的侧壁(如图8所示),或者是导电柱110c具有阶梯型(stepped)的侧壁,而焊点108具有弧形的侧壁(arc-sidewalls)(如图19所示)。
图16A至图16C为图8的集成扇出型封装的制造过程的各种阶段的立体示意图。详细地说,如图16A与图16B所示,在模板10上提供多个预制的导电柱110a,并将导电柱110a放置在模板10的多个孔洞12a中。在一些实施例中,预制的导电柱110a包括铜柱或其他合适的金属柱。举例来说,通过振动机器(vibration machine)振动模板10,使得预制的导电柱110a可部分插入模板10的孔洞12a中。由于导电柱110a是预先制作的,因此,容易制造出具有预定高宽比的导电柱110a。此外,由于导电柱110a不需要通过溅镀工艺、光刻工艺、电镀工艺以及光刻胶剥除工艺来制造,因此,可减少导电柱110a的制造成本与制造周期(fabrication cycle time)。
在一些实施例中,导电柱110a可被预先制作。预制的导电柱110a的特性(例如宽度、高度、形状、导电性等)可事先检查。因此,导电柱110a的生产良率可被提升。
请参照图16B与图16C,将载体C倒置(flipped)在模板10上(也就是说将载体C上下翻转)。后续步骤请参照图17A至图17C。
图17A至图17C为图16C的A-A’切线的集成扇出型封装的制造过程的各种阶段的剖面示意图。图18为依照本发明的替代实施例的一种模板的剖面示意图。如图17A与图17B所示,倒置的载体C上的焊膏107面向模板10的孔洞12a中的导电柱110a,使得焊膏107对准模板10的孔洞12a中的导电柱110a。在一些实施例中,导电柱110a可以是I型导电柱且配置在图17A的由盲孔所形成的孔洞12a中。在替代实施例中,如图18所示,导电柱110b也可以是T型导电柱(如图19所示)或其他合适形状且容易制造的导电柱,其配置在由通孔所形成的孔洞12b中。
接着,如图17B与图17C所示,将倒置的载体C上的焊膏107与导电柱110a的表面111a接触。之后,进行回焊工艺,使得焊膏107经回焊以形成焊点108,且导电柱110a通过焊点108固定在第一重配置导电层102b上(如图17C所示)。由于焊膏107的熔点小于导电柱110a的熔点,因此,当回焊温度达到焊膏107的熔点时,焊膏107会先熔融,以达到接合功效。此时,导电柱110a仍维持其形状而不熔融。
在替代实施例中,当载体C倒置并接合在模板10上时,第一重配置导电层102c并未与模板10的上表面接触。在第一重配置导电层102b与导电柱110a的表面111a接合后,驱动载体C向上移动并从模板10的孔洞12a中拉出导电柱110a。焊点108提供足够的附着力以从模板10的孔洞12a中拉出导电柱110a,使得导电柱110a转移接合(transfer-bonded)至第一重配置导电层102b。然后,再次将载体C上下翻转,如图17C所示,使得固定在第一重配置导电层102b上的导电柱110a的表面111a面向下(也就是说朝向载体C),而导电柱110a的表面111b面向上变成上表面111b。
如图17B与图17C所示,由于模板10的孔洞12a具有平坦的下表面且预制的导电柱110a具有相似或相同的高度,因此,图17C的导电柱110a的上表面111b的共面性比习知电镀后的导电柱好。在安置导电柱110a之后,多个导电柱110a的上表面111b实质上共平面,而不需要进行后续导电柱110a的研磨工艺。如此一来,可进一步地减少本发明实施例的集成扇出型封装的制造成本与制造周期。
图19为图8的导电柱的放大部分剖面示意图。请参照图19,将导电柱110c从模板10转移接合至第一重配置导电层102b之后,导电柱110c的底部可位在焊点108a上或内埋于焊点108b中。导电柱110c下方的焊点108b的厚度t2可小于导电柱110c的高度t3。导电柱110c的高度t3可例如是100微米(μm)至500微米,而导电柱110c下方的焊点108b的厚度t2可例如是2微米至10微米。在一些实施例中,t2/t3的比值为0.004至0.1。在一些实施例中,导电柱110c的底部的内埋深度t1可小于导电柱110c的高度t3的三分之一。也就是说,t1/t3的比值小于三分之一。在一些实施例中,导电柱110c的底部的内埋深度t1可小于30微米。在替代实施例中,导电柱110c的底部的内埋深度t1可小于10微米。多个导电柱110c之间的上表面111b的水平高度差(level height different)ΔH可小于10微米。此水平高度差ΔH可视为共平面,而不影响后续工艺,因此,导电柱110c的研磨工艺可被省略。
详细地说,如图19所示,焊点108a、108b中的至少一者具有弧形侧壁S108,其朝着相对应的焊点108a、108b的中心凹陷。以焊点108a为例,焊点108a具有锥形(tapered)侧壁S108。焊点108a的水平截面积自第一重配置导电层102b往对应的导电柱110c的方向渐缩。在一些实施例中,焊点108a的上部宽度W2等于位在焊点108a上的导电柱110c的下部宽度W1,而焊点108a的下部宽度W3大于位在焊点108a上的导电柱110c的下部宽度W1。在替代实施例中,由于焊点108b覆盖对应的导电柱110c的侧壁S110的一部分,因此,焊点108b的上部宽度W4大于位在焊点108b上的导电柱110c的下部宽度W1,其中上部宽度W4位在焊点108b与导电柱110c之间的界面处。换言之,在回焊工艺之后,焊点108b的顶面具有凹陷R。凹陷R的深度t1可例如小于10微米。导电柱110c的底部可部分插入所述凹陷R中。
请回头参照图8与图9,通过黏胶(adhesive)AD将晶粒112安置在第一重配置导电层102c上。在一些实施例中,晶粒112可通过黏胶AD直接接合至第一重配置导电层102c上。黏胶AD填入第一重配置导电层102c中的开口并覆盖第一重配置导电层102c的上表面。因此,晶粒112通过黏胶AD与第一重配置导电层102c电性绝缘。在一些实施例中,黏胶AD可以是芯片贴覆膜(die attach film,DAF)或线路上覆膜(film over wire,FoW)。晶粒112具有有源表面112a以及相对于有源表面112a的背面112f。在一些实施例中,晶粒112包括多个接垫112b、钝化层112c以及多个导电柱112d。钝化层112c覆盖有源表面112a以及部分接垫112b。接垫112b部分外露于钝化层112c。导电柱112d形成在接垫112b上,并与接垫112b电性连接。晶粒112的背面112f与黏胶AD接触。导电柱112d可例如是铜柱或其他合适的金属柱。
在图9中,虽然只有一个晶粒112安置在第一重配置导电层102c上。然而,晶粒112的数量仅是用以说明,本发明不限于此。在替代实施例中,可将多个晶粒112安置在第一重配置导电层102c上,且安置在第一重配置导电层102c上的晶粒112可排列成数组(array)。当多个晶粒112安置在第一重配置导电层102c上,多个导电柱110的群组可被安置在第一重配置导电层102b上,且导电柱110的群组中的一者环绕各晶粒112。
参照图10,在载体C上形成绝缘材料(未示出)以覆盖焊点108、导电柱110以及晶粒112的表面。在一些实施例中,绝缘材料可以是通过模制工艺(molding process)所形成的模制化合物(molding compound)。在一些实施例中,绝缘材料可包括环氧化合物或其他适合的材料。接着,研磨绝缘材料以及部分晶粒112以暴露出导电柱112d的上表面113d。研磨绝缘材料之后,绝缘包封体114形成在第一重配置线路结构102上,以包封晶粒112的侧壁、导电柱110的侧壁以及焊点108的侧壁。在一些实施例中,在上述研磨工艺期间,部分绝缘材料、部分导电柱112d以及部分导电柱110被移除,以暴露导电柱112d的上表面113d与导电柱110的上表面111b。在一些实施例中,绝缘包封体114可通过机械研磨法和/或化学机械研磨法(CMP)形成。
绝缘包封体114包封晶粒112的侧壁以及导电结构130的侧壁。换言之,导电结构130与晶粒112内埋在绝缘包封体114中。也就是说,导电结构130(其包括焊点108与导电柱110)贯穿绝缘包封体114,且暴露出导电柱110的上表面111b。需注意的是,在经过研磨工艺后,导电柱110的上表面111b、导电柱112d的上表面113d以及绝缘包封体114的上表面114a实质上共平面。
在替代实施例中,由于导电柱110的上表面111b之间的共面性够好,因此,研磨工艺可被省略。详细地说,当晶粒112安置在第一重配置导电层102c上之后,导电柱110的上表面111b以及导电柱112d的上表面113d实质上共平面。可将离形膜(未示出)附着在导电柱110的上表面111b以及导电柱112d的上表面113d上。接着,利用模具固定具有离形膜、晶粒112以及导电柱110的载体C。之后,将绝缘材料填入离形膜、晶粒112以及导电柱110之间的空隙,并接着固化,以形成绝缘包封体114。换言之,离形膜可避免绝缘包封体114附着在导电柱110的上表面111b以及导电柱112d的上表面113d上。因此,本发明实施例可省略研磨工艺,以减少制造成本与制造周期。
请参照图11,在形成绝缘包封体114之后,在导电柱110的上表面111b上、绝缘包封体114的上表面114a上以及导电柱112d的上表面113d上形成第二重配置线路结构116。如图11所示,第二重配置线路结构116包括交替叠层的多个第二介电层116a以及多个第二重配置导电层116b。第二重配置导电层116b与晶粒112的导电柱112d以及导电柱110电性连接。也就是说,导电结构130(其包括焊点108与导电柱110)电性连接第一重配置线路结构102与第二重配置线路结构116。在一些实施例中,导电柱112d的上表面113d以及导电柱110的上表面111b接触第二重配置线路结构116的最底的第二重配置导电层116b。最底部的第二介电层116a部分覆盖导电柱112d的上表面113d以及导电柱110的上表面111b。此外,最顶的第二重配置导电层116b具有多个接垫。在一些实施例中,上述接垫包括多个球底金属(under-ball metallurgy,UBM)图案116b1和/或至少一个连接接垫116b2。UBM图案116b1可用以安置焊球,而连接接垫116b2可用以安置无源组件(passive components)。UBM图案116b1以及连接接垫116b2的数量不限于本发明。
请参照图12,在形成第二重配置线路结构116之后,在UBM图案116b1上安置多个导电端子(conductive terminals)118,并在连接接垫116b2上安置多个无源组件120。在一些实施例中,可通过植球工艺将导电端子118安置在UBM图案116b1上,并可通过焊接工艺或回焊工艺将无源组件120安置在连接接垫116b2上。
请参照图12与图13,在第二重配置线路结构116上安置导电端子118与无源组件120之后,将第一介电层102a与剥离层DB剥离,使得第一介电层102a与剥离层DB以及载体C分离或分层。在一些实施例中,剥离层DB(例如是光热转换释放层)可通过照射紫外光激光,以使第一介电层102a与载体C剥离。
如图13所示,接着,图案化第一介电层102a,以形成多个接触开口122并暴露出第一重配置导电层102b的下表面。在一些实施例中,第一介电层102a中的接触开口122的数量对应于第一重配置导电层102b的数量。
请参照图14,在第一介电层102a中形成接触开口122之后,多个导电端子124(例如是导电球)被放置在外露于接触开口122的第一重配置导电层102b的下表面上。在一些实施例中,导电端子124(例如是导电球)可被回焊以固定在第一重配置导电层102b的被暴露的表面上。换句话说,导电端子124与第一重配置导电层102b电性连接。如图14所示,在形成导电端子118、124之后,可完成具有双侧端子(dual-side terminals)的集成扇出型封装100。
请参照图15,接着提供另一种封装200。在一些实施例中,封装200可以是存储元件。封装200通过导电端子124叠层并电性连接至图14的集成扇出型封装100,以制造出叠层式封装(package-on-package,POP)结构。
根据一些实施例,晶粒可通过黏胶直接安置在第一重配置线路结构上。另外,晶粒的背面上的第一重配置线路结构以及晶粒的有源面上的第二重配置线路结构可通过多个焊点与多个导电柱相互连接。导电柱可通过焊点安置在第一重配置线路结构上。焊点形成在第一重配置线路结构与导电柱之间,以提升导电柱的上表面之间的共面性。
