Description
技术领域
本公开实施例涉及一种半导体封装体及其制造方法。
背景技术
半导体装置用于各种电子应用,例如(举例来说)个人计算机、手机、数字相机及其他电子设备。半导体装置通常通过在半导体衬底之上依序沉积绝缘层或介电层以及导电层以及使用光刻将各个材料层图案化以在半导体衬底上形成电路组件及元件。
在尝试进一步提高电路密度时,已探究了三维(three-dimensional,3D)集成电路(integrated circuit,IC)。在三维集成电路的典型形成工艺中,将两个管芯接合在一起,且在每一管芯与衬底上的接触焊盘之间形成电连接。中介层堆叠是三维集成电路技术的一部分,其中嵌入有硅穿孔(Through-Silicon-Via,TSV)的中介层利用微凸块连接到装置硅。三维集成电路制造工艺流程可被分成两种类型。在衬底上晶片上芯片(chip-on-wafer-on-substrate,CoWoS)工艺流程中,首先将装置硅芯片贴合到硅中介层晶片,接着对硅中介层晶片进行划切。接着将所得的堆叠硅贴合到衬底上。
然而,一些半导体封装体趋于表现出翘曲,其中在处理期间(例如在温度应力期间)出现衬底的翘曲。所述翘曲可能造成可靠性问题(例如贴合到半导体装置的膜型热界面材料的分层),且这种分层将引起半导体封装体的大的热阻。
发明内容
根据本公开的实施例,一种半导体封装体包括重布线结构、至少一个半导体装置以及多个散热膜。所述至少一个半导体装置安装在所述重布线结构上。所述多个散热膜以并排的方式设置在所述至少一个半导体装置上且共同地覆盖所述至少一个半导体装置的上表面。
根据本公开的实施例,一种半导体封装体包括衬底、经包封半导体封装体、多个散热膜以及封盖。所述经包封半导体封装体设置在所述衬底上。所述多个散热膜以并排的方式设置在所述经包封半导体封装体上且覆盖所述经包封半导体封装体的上表面。所述封盖设置在所述衬底上且接触所述多个散热膜。
根据本公开的实施例,一种制造半导体封装体的方法包括:在衬底上提供经包封半导体封装体;将散热片材切割成多个散热膜;将所述多个散热膜贴合在所述经包封半导体封装体上,其中所述多个散热膜共同地覆盖所述经包封半导体封装体的上表面;在所述衬底上提供封盖,其中所述封盖接触所述多个散热膜。

具体实施方式
以下公开内容提供用于实施所提供主题的不同特征的许多不同的实施例或实例。以下阐述组件及排列的具体实例以简化本公开。当然,这些仅为实例而非旨在进行限制。举例来说,在以下说明中,在第二特征之上或第二特征上形成第一特征可包括其中第一特征与第二特征被形成为直接接触的实施例,且也可包括其中第一特征与第二特征之间可形成附加特征从而使得第一特征与第二特征可不直接接触的实施例。另外,本公开在各种实例中可重复使用参考编号和/或字母。此种重复使用是为了简明及清晰起见,且自身并不表示所论述的各个实施例和/或配置之间的关系。
此外,为易于说明,本文中可能使用例如“在…之下”、“在…下方”、“下部的”、“在…上方”、“上部的”等空间相对性用语来阐述图中所示一个元件或特征与另一(其他)元件或特征的关系。除图中所绘示的取向以外,所述空间相对性用语旨在涵盖装置在使用或操作中的不同取向。设备可被另外取向(旋转90度或处于其他取向),且本文所使用的空间相对性描述语可同样相应地作出解释。
还可包括其他特征及工艺。举例来说,可包括测试结构以帮助进行三维封装体或三维集成电路装置的验证测试。测试结构可包括例如形成在重布线层中或衬底上的测试焊盘,以使得能够测试三维封装体或三维集成电路、使用探针(probe)和/或探针卡(probecard)等。可对中间结构及最终结构执行验证测试。另外,本文中所公开的结构及方法可接合包括对已知良好管芯的中间验证的测试方法一起使用,以提高良率并降低成本。
对于本文中提供的实施例来说,可在特定的上下文(即,将散热片材切割成多个散热膜并将散热膜贴合到经包封半导体装置上)中论述所述技术。在加热工艺期间,半导体封装体可能会发生翘曲,且以共同尺寸来切割的散热膜会提高散热膜与经包封半导体装置之间的粘附力,从而通过降低散热膜与经包封半导体装置之间分层的可能性来提高散热效率。
根据本公开的一些实施例,制造工艺可包括使用衬底上晶片上芯片(CoWoS)封装处理形成多芯片封装结构。其他实施例也可使用包括集成扇出型(integrated fan-out,InFO)封装处理在内的其他处理。本文中所论述的实施例是为了提供能够提出或使用本公开主题的实例,且所属领域中的一般技术人员将容易地理解可作出修改而所述修改同时保持在不同实施例的预期范围内。相同的参考编号及字符在以下图中指代相同的组件。尽管方法实施例可被论述为以特定顺序执行,但是其他方法实施例可以任何逻辑顺序执行。
图1到图9示出根据本公开一些示例性实施例的半导体封装体的制造中的中间阶段的剖视图。现参照图1,提供重布线结构200。在一些实施例中,重布线结构200可为中介层(interposer),所述中介层包括衬底202、多个穿孔204以及多个导电焊盘206于其中。在一些实施例中,衬底202可包括块状半导体衬底、绝缘体上硅(silicon on insulator,SOI)衬底或多层式半导体材料衬底。衬底202的半导体材料可为硅、锗、硅锗、碳化硅、砷化镓、磷化镓、磷化铟、砷化铟、锑化铟、GaAsP、AlInAs、AlGaAs、GaInAs、GaInP、GaInAsP、或其组合。在一些实施例中,衬底202可为经掺杂或未经掺杂的。在一些实施例中,导电焊盘206形成在中介层(重布线结构200)的第一表面202a上。在一些实施例中,穿孔204形成在衬底202中并与导电焊盘206连接。在一些实施例中,穿孔204以特定深度延伸到衬底202中。在一些实施例中,穿孔204是衬底穿孔。在一些实施例中,当衬底202是硅衬底时,穿孔204是硅穿孔。在一些实施例中,穿孔204可通过在衬底202中形成孔或凹槽以及接着利用导电材料填充凹槽来形成。在一些实施例中,凹槽可通过例如刻蚀、铣削(milling)、激光钻孔等形成。在一些实施例中,导电材料可通过电化学镀覆工艺、化学气相沉积(chemical vapor deposition,CVD)、原子层沉积(atomic layer deposition,ALD)或物理气相沉积(physical vapordeposition,PVD)形成,且导电材料可包括铜、钨、铝、银、金或其组合。
根据本公开的一些实施例,与穿孔204连接的导电焊盘206可被形成为形成在重布线结构200上的重布线层的导电部分。在一些实施例中,导电焊盘206包括凸块下金属(under bump metallurgy,UBM)。在某些实施例中,中介层(重布线结构200)还可包括有源装置或无源装置,例如形成在衬底202中的晶体管、电容器、电阻器或二极管无源装置。

根据本公开的一些实施例,半导体装置12、半导体装置14与重布线结构200之间的接合可为焊料接合。在一些实施例中,半导体装置12、半导体装置14与重布线结构200之间的接合可为直接金属对金属接合,例如铜对铜接合。在一些实施例中,可向半导体装置12、半导体装置14与环绕导电接头230的重布线结构200之间的间隙分配底部填充材料(未示出)。
现参照图2,在重布线结构200之上形成包封材料240,且包封材料240覆盖半导体装置12、半导体装置14以及导电接头230。在一些实施例中,包封材料240可为模制化合物。在一些实施例中,包封材料240包含环氧树脂,且可通过压缩模制或转移模制形成。在一个实施例中,执行固化工艺来固化包封材料240。在一些实施例中,半导体装置12、半导体装置14及导电接头230由包封材料240包封。在一些实施例中,可执行平坦化工艺(包括研磨或抛光)以部分地移除包封材料240,从而暴露出第一管芯(半导体装置12)及第二管芯(半导体装置14)的背侧表面12S、背侧表面14S。因此,半导体装置12、半导体装置14的上表面(背侧表面12S、背侧表面14S)与包封材料240的顶表面240a共面(等高)。
现参照图3,将图2所示结构倒置或翻转,并放置在载体C上,使得载体C直接接触第一管芯(半导体装置12)及第二管芯(半导体装置14)的背侧表面12S、背侧表面14S以及包封材料240的顶表面240a。如图3所示,在此处理阶段,重布线结构200没有减薄且具有厚度T1。
现参照图4,在重布线结构200为中介层的实施例中,可对中介层200执行减薄工艺以部分地移除或减薄中介层(重布线结构200)的衬底202,直到穿孔204裸露出且形成中介层的第二表面202b为止。在一些实施例中,减薄工艺可包括背面研磨工艺、抛光工艺或刻蚀工艺。在一些实施例中,在减薄工艺之后,中介层(重布线结构200)减薄到厚度T2。
现参照图5,在衬底202(中介层(重布线结构200))的第二表面202b上形成重布线层300。在一些实施例中,重布线层300电连接多个穿孔204和/或电连接穿孔204与外部装置。在某些实施例中,重布线层300包括至少一个介电层302及介电层302中的多个金属化图案304。在一些实施例中,金属化图案304可包括焊盘、通孔和/或迹线以对穿孔204进行内连,并进一步将穿孔204连接到一个或多个外部装置。尽管在图5及以下图中示出一层介电层,但是在重布线结构中可包括多于一个介电层。在一些实施例中,介电层302的材料包括氧化硅、氮化硅、碳化硅、氮氧化硅或低介电常数介电材料(例如磷硅酸盐玻璃材料、氟硅酸盐玻璃材料、硼磷硅酸盐玻璃材料、SiOC、旋涂玻璃材料、旋涂聚合物或硅化碳材料)。在一些实施例中,介电层302可通过旋转涂布或沉积(包括化学气相沉积(CVD)、等离子体增强化学气相沉积(plasma-enhanced chemical vapor deposition,PECVD)、高密度等离子体化学气相沉积(high density plasma chemical vapor deposition,HDP-CVD)等)形成。在一些实施例中,金属化图案304包括凸块下金属(UBM)。在一些实施例中,金属化图案304的形成可包括使用光刻技术及一个或多个刻蚀工艺将介电层图案化以及将金属材料填充到经图案化的介电层的开口中。可例如通过使用化学机械抛光工艺移除介电层上的任何过量的导电材料。在一些实施例中,金属化图案304的材料包括铜、铝、钨、银及其组合。
现参照图6,在金属化图案304上设置电耦合到穿孔204的电连接件350。在一些实施例中,电连接件350被放置在重布线层300的顶表面300s上,并且被定位在金属化图案304上。在一些实施例中,电连接件350包括无铅焊料球、焊料球、球栅阵列(ball grid array,BGA)球、凸块、C4凸块或微凸块。在一些实施例中,电连接件350可包括导电材料,例如焊料、铜、铝、金、镍、银、钯、锡或其组合。在一些实施例中,电连接件350通过例如蒸镀、电镀、印刷或焊料转移在重布线层300上形成焊料膏且接着使所述焊料膏回焊成期望的凸块形状来形成。在一些实施例中,电连接件350通过植球等被放置在重布线层300上。在其他实施例中,电连接件350通过溅射、印刷、化学镀敷或电镀覆或者CVD形成无焊料金属柱(例如铜柱)以及接着通过在金属柱上进行镀覆形成无铅顶盖层来形成。
根据本公开的一些实施例,电连接件350可用于接合到外部装置或附加电组件。在一些实施例中,电连接件350用于接合到衬底,例如电路衬底、半导体衬底或封装衬底等。
现参照图7,执行单体化工艺以沿着封装单元PKU周围的切割道SL将图6所示封装结构切割成多个封装体。在整个说明中,图7所示的包括半导体装置12、半导体装置14、包封材料240、重布线结构200的封装体被称为经包封半导体封装体70。因此,多个经包封半导体封装体70中的每一者包括至少一个半导体装置12/半导体装置14、环绕半导体装置12/半导体装置14的包封材料240、包括穿孔204的重布线结构200、包括介电层302及金属化图案304的重布线层300以及设置在重布线层300的表面(顶表面300s)上的电连接件350。在一些实施例中,单体化工艺可包括锯切(sawing)工艺或划切(dicing)工艺。
在单体化工艺之后,将经包封半导体封装体70从载体C分离并移除载体C。在随后的工艺中,可将经包封半导体封装体70翻转并进一步安装在衬底80(例如电路衬底或封装衬底等)上。
现参照图8,提供上面有安装部分802的衬底80。在一些实施例中,衬底80可放置在安装在平台上的衬底夹具(未示出)上。衬底夹具可为具有多于一个夹具单元的平板夹具。在一些实施例中,衬底80可包括构成衬底、叠层衬底、电路板(例如印刷电路板(printedcircuit board,PCB))等。在一些实施例中,安装部分802可包括形成在衬底80的焊盘上的预焊料。另外,衬底80还可包括电接触件或其中的其他电组件。
图13示出根据本公开一些示例性实施例的半导体封装体的制造工艺的方块图。现参照图8及图13,执行步骤S110,在衬底80上提供至少一个经包封半导体封装体70。在一些实施例中,经包封半导体封装体70被设置成使其底表面70BS面对衬底80。在图8中,尽管示出一个经包封半导体封装体70及一个衬底80,但是可使用多个封装体及多个电路衬底。在一些实施例中,在回焊工艺之前,经包封半导体封装体70(以及半导体装置12、半导体装置14)可能稍微翘曲,但是在回焊工艺之前,经包封半导体封装体70的翘曲程度可小于在经历回焊工艺时经包封半导体封装体70的翘曲程度。
根据本公开的一些实施例,将经包封半导体封装体70放置在衬底80上,且接着执行回焊工艺RFL。在一些实施例中,将经包封半导体封装体70拾取并放置在衬底80的顶表面之上,且封装体70的底表面70BS上的电连接件350对准并设置在衬底80的安装部分802上。执行回焊工艺作为经包封半导体封装体70及衬底80的接合工艺的一部分以将电连接件350接合到安装部分802。在一些实施例中,回焊工艺包括在回焊温度下对电连接件350及安装部分802执行热加热工艺,以使电连接件350变成熔化状态或半熔化状态,以与衬底80的安装部分802集成及接合。电连接件350的回焊温度需要高于电连接件350的熔点。在一个实施例中,电连接件是C4凸块,回焊温度介于210℃到250℃的范围内。在一个实施例中,电连接件350是焊料球或无铅焊料球,回焊温度介于200℃到260℃的范围内。
根据本公开的一些实施例,在热处理工艺(例如回焊工艺)期间,在热冲击下,衬底80、半导体装置(以及半导体装置12、半导体装置14)由于热膨胀系数(coefficient ofthermal expansion,CTE)失配而发生翘曲。在一些实施例中,翘曲的经包封半导体封装体70的几何形状可对应于并根据翘曲的衬底80的几何形状。在本实施例中,经包封半导体封装体70弯曲并变得凸起(哭脸形状(cry-shape)),但是本公开并非仅限于此。
现参照图9及图13,为减少(校正)经包封半导体封装体70及衬底80的翘曲,可在衬底80上提供图9所示封盖500,且封盖500通过热界面材料(thermal interface material,TIM)附接到经包封半导体封装体70的上表面。在一些实施例中,热界面材料可为从散热片材切割(步骤S120)下来的多个散热膜400。在一些实施例中,散热膜400可包含导热材料及电绝缘材料,例如环氧树脂,如同与金属(如银或金)混合的环氧树脂、“热油脂”、“白色油脂”等或其组合。举例来说,在一些实施例中,作为实例,散热膜400的材料可包括环氧树脂、硅酮、无机材料(例如轻度交联硅酮聚合物、一种或多种基质聚合物、具有一种或多种导热填料的聚合物)、其他材料或其多个层或其组合。在包含基质聚合物的散热膜400的实施例中,基质聚合物可包括乙烯-丙烯、乙烯-丙烯-二烯单体、氢化聚异戊二烯或其组合。在包含导热填料的散热膜400的实施例中,导热填料可包括氧化铝、氮化硼、氮化铝、铝、铜、银、铟或其组合。导热填料分散在散热膜400内。作为另外一种选择,散热膜400可包含其他材料、填料及属性。本公开并非仅限于此。
根据本公开的一些实施例,封盖500的材料可包括钢,且在其他实施例中,可为铜、不锈钢等或其组合。可将散热膜400贴合到经包封半导体封装体70的上表面并共同地覆盖(贴合到)经包封半导体封装体70的上表面(步骤S130)。在一些实施例中,使用拾取及放置工具将散热膜400贴合到经包封半导体封装体70的上表面。接着可使用拾取及放置工具(可与用于散热膜400的拾取及放置工具相同或相似)将封盖500放置在散热膜400上(步骤S140),以将封盖500贴合到经包封半导体封装体70的剩余部分。在一些实施例中,封盖500接触散热膜400。举例来说,在一些实施例中,封盖500可用作散热器。在其他实施例中,散热器(未示出)还可设置在封盖500上以用于增强散热。在替代实施例中,封盖可包括多个靠近封盖的顶表面设置的向上延伸的鳍。
图10示出根据本公开一些示例性实施例的半导体封装制造中的中间阶段的俯视图。图11示出根据本公开一些示例性实施例的半导体封装制造中的中间阶段的俯视图。现参照图10及图11,在一些实施例中,图10示出在散热膜400放置在衬底80上之前安装在衬底80上的经包封半导体封装体70的俯视图。图11示出在放置散热膜400之后及在将封盖500放置在散热膜400上之前的结构的俯视图。应注意,图10中的经包封半导体封装体70(半导体装置12、半导体装置14)的布局设计可与图8所示经包封半导体封装体70(半导体装置12、半导体装置14)的布局设计稍微不同。然而,图10所示经包封半导体封装体70可通过与图1到图8中所阐述的相同或至少相似的制造工艺形成。在一些实施例中,可在衬底80的将被附接封盖(例如,图9所示封盖500)的外围区上分配粘合剂804,以将封盖附接到衬底80。当安装封盖时,可施加压力,并使粘合剂804固化。在一些实施例中,粘合剂804可包括高转变温度(transition temperature)的粘合剂。作为另外一种选择,可使用其他类型的粘合剂804。
根据本公开的一些实施例,如图11所示,以共同尺寸将散热片材切割成多个散热膜400。在一些实施例中,散热膜400的尺寸可相同。然而,在其他实施例中,根据半导体装置12、半导体装置14的实际需要及布局设计,散热膜400的尺寸可彼此不同。在一些实施例中,散热膜400以并排的方式设置在经包封半导体封装体70上。更具体来说,散热膜400可以并排的方式设置在半导体装置12、半导体装置14的上表面(背侧表面)上,且共同地覆盖(接触)半导体装置12、半导体装置14的上表面,如图11所示。在一些实施例中,散热膜400也可覆盖包封材料240。也就是说,散热膜400中的至少一者可设置在包封材料240的顶表面上。
在一些实施例中,散热膜400的尺寸可不对应于且不根据半导体装置12、半导体装置14的尺寸。换句话说,从俯视图看,多个散热膜400中的每一者的边缘可不与半导体装置12、半导体装置14中的每一者的边缘对准。对于具有一个半导体装置12或半导体装置14的半导体封装体的实施例来说,散热膜400可共同地覆盖所述一个半导体装置12或半导体装置14。对于具有多个半导体装置12及多个半导体装置14的半导体封装体的实施例来说,彼此相邻的多个散热膜400中的两个散热膜400可共同地覆盖半导体装置12/半导体装置14中的一者。
利用这种排列,将散热膜400切割成更小的片以贴合到经包封半导体封装体70。因此,小片散热膜400可容易地对应于经包封半导体封装体70的形状或半导体装置12、半导体装置14的轮廓,而不必为每一产品定制散热片。因此,散热膜400的排列提高了半导体封装体10的生产率及工艺灵活性。
此外,小片散热膜400可容易地对应于经包封半导体封装体70的上表面的曲率(翘曲)。因此,可避免或至少减少经包封半导体封装体70的高度翘曲区处的散热膜400的分层。分层将在半导体封装体10中导致大的热阻。因此,散热膜400的排列提高了半导体封装体10的良率及散热效率。
图12示出根据本公开一些示例性实施例的半导体封装制造中的中间阶段的俯视图。应注意,图12所示半导体封装体包含与先前结合图9到图11公开的半导体封装体相同或相似的许多特征。为清晰及简洁起见,可省略对相同或相似特征的详细说明,且相同或相似的参考编号表示相同或相似的组件。图12所示半导体封装体与图9到图11所示半导体封装体之间的主要区别阐述为如下。
现参照图9及图12,散热膜400包括至少一个第一散热膜400a及至少一个第二散热膜400b。在一些实施例中,第一散热膜400a的厚度和/或粘性不同于第二散热膜400b的厚度和/或粘性。在一些实施例中,第一散热膜400a的厚度可显著大于第二散热膜400b的厚度。利用这种排列,第一散热膜400a可贴合到经包封半导体封装体70的高度翘曲区(例如,外围区),且第二散热膜400b可贴合到经包封半导体封装体70的低翘曲区(例如,中心区)。也就是说,经包封半导体封装体70的贴合第一散热膜400a的区具有比经包封半导体封装体70的贴合第二散热膜400b的另一区高的翘曲。因此,当第一散热膜400a及第二散热膜400b贴合到翘曲的经包封半导体封装体70时,封盖500仍可与第一散热膜400a及第二散热膜400b牢固接触。
根据本公开的一些实施例,第一散热膜400a的粘性可显著大于第二散热膜400b的粘性。利用这种排列,第一散热膜400a可贴合到经包封半导体封装体70的高度翘曲区(例如,外围区),且第二散热膜400b可贴合到经包封半导体封装体70的低翘曲区(例如,中心区)。因此,可避免或至少减少经包封半导体封装体70的高度翘曲区处的第一散热膜400a的分层。在一些实施例中,第一散热膜400a的厚度及粘性均可大于第二散热膜400b的厚度及粘性。因此,可避免或减少经包封半导体封装体70的高度翘曲区处的第一散热膜400a的分层,且封盖500可与第一散热膜400a及第二散热膜400b牢固接触,从而改善半导体封装体的散热。
基于以上论述,可看出本公开提供各种优点。然而,应理解,本文中未必论述所有优点,且其他实施例可提供不同的优点,且对于所有实施例来说并不需要特定优点。
