Description
技术领域
本发明涉及半导体技术领域,尤其涉及一种半导体封装结构。
背景技术
随着对具有更多功能的更小装置的需求增加,垂直堆叠两个或更多半导体芯片或半导体晶粒的三维集成电路(three-dimensional integrated circuit,3DIC)封装技术变得越来越流行。3D IC封装技术采用引线接合(wire bonding)、倒装芯片(flip chip)等互连方式实现垂直堆叠。因此,在3D IC封装中,可以降低制造成本,并且可以在比传统二维(two-dimensional,2D)IC封装技术更低的功率和更小的占用空间下实现性能改进。
然而,虽然现有的半导体封装结构通常是足够的,但是它们在各个方面都不是令人满意的。3D IC封装技术带来了新的挑战,例如热(thermal)或供电网络(power deliverynetwork,PDN)设计问题。这些问题降低了半导体封装结构的可靠性。因此,需要进一步改进半导体封装结构。
发明内容
有鉴于此,本发明提供一种半导体封装结构,以解决上述问题。
根据本发明的第一方面,公开一种半导体封装结构,包括:
正面重分布层;
第一半导体晶粒,设置在该正面重分布层上方;
第一电容器,设置在该正面重分布层上方并电耦接到该第一半导体晶粒;
导电端子,设置在该正面重分布层下方并电性连接至该正面重分布层;以及
背面重分布层,设置在该第一半导体晶粒上方。
根据本发明的第二方面,公开一种半导体封装结构,包括:
基板,具有布线结构;
半导体晶粒,设置在该基板上方并电耦接到该布线结构;
凸块结构,邻近该半导体晶粒;
模制材料,围绕该半导体晶粒和该凸块结构;以及
电容器结构,设置在该模制材料上并通过该凸块电耦和该布线结构耦接到该半导体晶粒。
根据本发明的第三方面,公开一种半导体封装结构,包括:
重分布层;
多电容器结构,设置于该重分布层下方;
底部半导体晶粒,设置在该重分布层上方并具有通孔,其中该底部半导体晶粒通过该重分布层电耦接到该多电容器结构;以及
顶部半导体晶粒,设置在该底部半导体晶粒上方并且通过该通孔和该重分布层电耦接到该多电容器结构。
本发明的半导体封装结构由于包括:正面重分布层;第一半导体晶粒,设置在该正面重分布层上方;第一电容器,设置在该正面重分布层上方并电耦接到该第一半导体晶粒;导电端子,设置在该正面重分布层下方并电性连接至该正面重分布层;以及背面重分布层,设置在该第一半导体晶粒上方。与具有焊盘侧电容的半导体封装结构相比,根据本发明的半导体封装结构具有不占用导电端子空间的电容器,可以增加设计的灵活性。

根据本发明的一些实施例描述了包括电容器的半导体封装结构。与去除部分导电端子为电容器提供空间的实施例相比,本发明实施例可以保留更多的导电端子。此外,在一些实施例中,可以降低制造半导体封装结构的复杂性。
图1A是根据本发明的一些实施例的半导体封装结构100的截面图。可以向半导体封装结构100添加附加特征。对于不同的实施例,可以替换或消除下面描述的一些特征。为简化示意图,仅绘示半导体封装结构100的一部分。
如图1A所示,根据一些实施例,半导体封装结构100包括重分布层,重分布层可以包括多个导电层RDL1、RDL2、RDL3和RDL4。仅出于说明的目的示出四个导电层RDL1、RDL2、RDL3和RDL4,并且可以存在多于或少于四个导电层。
在一些实施例中,重分布层包括多个钝化层(在图1A中省略而未示出),并且导电层RDL1、RDL2、RDL3和RDL4设置在钝化层中。导电层RDL1、RDL2、RDL3和RDL4可以通过钝化层中的多个导电通孔116彼此电耦接。
导电层RDL1、RDL2、RDL3和RDL4可以由金属形成,例如铜、钛、钨、铝等或其组合。导电通孔116可由金属形成,例如铜、钛、钨、铝等或其组合。

根据一些实施例,第一半导体晶粒102和第二半导体晶粒104各自独立地包括系统单晶粒(system-on-chip,SoC)晶粒、逻辑器件、存储器器件、射频(radio frequency,RF)器件之类,或它们的任何组合。
例如,第一半导体晶粒102和第二半导体晶粒104可以各自独立地包括微控制单元(micro control unit,MCU)晶粒、微处理器单元(microprocessor unit,MPU)晶粒、电源管理集成电路(power management integrated circuit,PMIC)晶粒、全局定位系统(globalpositioning system,GPS)设备、加速处理单元(accelerated processing unit,APU)晶粒、中央处理单元(central processing unit,CPU)晶粒、图形处理单元(graphicsprocessing unit,GPU)晶粒、输入输出(input-output,IO)晶粒、动态随机接入存储器(dynamic random access memory,DRAM)控制器、静态随机接入存储器(static random-access memory,SRAM)、高带宽存储器(high bandwidth memory,HBM)等,或它们的任何组合。
根据一些实施例,半导体封装结构100还包括一个或多个无源元件(未示出),例如电阻器、电容器、电感器或其组合。

如图1A所示,根据一些实施例,半导体封装结构100包括设置在重分布层下方的多端子多电容器结构110。多端子多电容器结构110可以具有多个端子112,并且可以通过重分布层和端子112电耦接到第一半导体晶粒102和第二半导体晶粒104。
多端子多电容器结构110可以具有一个以上电容器和一个以上端子112,其中这些电容器分别电耦接到第一半导体晶粒102和第二半导体晶粒104。也就是说,多端子多电容器结构110可以是多电容器结构。
与半导体封装结构包括用于第一半导体晶粒102和第二半导体晶粒104的单独电容器的实施例相比,半导体封装结构100使用多端子多电容器结构110用于第一半导体晶102和第二半导体晶104,可以减少占用的空间。此外,可以提高设计灵活性。
如图1所示,第一半导体晶粒102和第二半导体晶粒104可以在与第一半导体晶粒102和第二半导体晶粒104的堆叠方向基本平行的方向上重叠多端子多电容器结构110。
在一些实施例中,两个半导体晶粒,第一半导体晶粒102和第二半导体晶粒104,共用一个多端子多电容器结构110,但本发明不限于此。例如,多于两个半导体晶粒可共用多端子多电容器结构110。或者,多于一个多端子多电容器结构可用于多个半导体晶粒。
图1B是根据一些实施例的半导体封装结构100的多端子多电容器结构110的俯视图。如图1B所示,多端子多电容器结构110可包括多个第一端子112a、多个第二端子112b以及多个接地端子112c。
第一端子112a可以电耦接到第一半导体晶粒102的电源端子。第二端子112b可以电耦接到第二半导体晶粒104的电源端子。接地端子112c可以电耦接到第一半导体晶粒102和第二半导体晶粒104的接地端子。特别地,第一半导体晶粒102的接地端子和第二半导体晶粒104的接地端子可以彼此连接并且接地。或者,第一半导体晶粒102的接地端子和第二半导体晶粒104的接地端子可以分别接地。
在一些实施例中,第一端子112a可以沿着第一条线布置,第二端子112b可以沿着第二条线布置,并且接地端子112c可以沿着第三条线布置。第一条线、第二条线和第三条线可以彼此平行。
接地端子112c可以设置在一列(column)第一端子112a和一列第二端子112b之间以及两列第二端子112b之间。图中所示的第一端子112a、第二端子112b和接地端子112c的数量和排列方式仅为示例性的,并不用于限制本发明。例如,第一端子112a可以沿着两条线布置,并且接地端子112c可以设置在两列第一端子112a之间。
返回参考图1A,根据一些实施例,半导体封装结构100包括多个导电端子114,其设置在重分布层下方并与多端子多电容器结构110相邻。即,多端子多电容器结构110可以设置在导电端子114之间。
导电端子114可以电耦接到重分布层。在一些实施例中,导电端子114由导电材料形成,例如金属。导电端子114可包括微凸块、受控塌陷芯片连接(controlled collapsechip connection,C4)凸块、焊球、球栅阵列(ball grid array,BGA)球等或其组合。
如图1A所示,多端子多电容器结构110可占据导电端子114的面积。此外,由于第一半导体晶粒102与第二半导体晶粒104垂直堆叠且投影面积相同根据资源,第一半导体晶粒102和第二半导体晶粒104下方的可用导电端子114的数量可以少于并排布置的半导体晶粒。
随着对更多功能和更小装置的需求不断增加,这些问题增加了集成用于不同半导体晶粒的单独电容器的难度。有鉴于此,本发明的半导体封装结构100采用多端子多电容器结构110代替单独的电容,可减少电容的占用面积,并可保留更多的导电端子114。
图2A是根据本发明的一些实施例的半导体封装结构200的截面图。需要说明的是,半导体封装结构200可以包括与图1所示的半导体封装结构100相同或相似的元件,为简单起见,不再赘述。在以下实施例中,多端子多电容器结构设置在基板下方。

多端子多电容器结构210可以具有一个以上电容器和一个以上端子212,其中这些电容器分别电耦接到第一半导体晶粒102和第二半导体晶粒104。也就是说,多端子多电容器结构210可以是多电容器结构。
如上所述,根据一些实施例,半导体封装结构200使用多端子多电容器结构210用于第一半导体晶粒102和第二半导体晶粒104可以减少占用的空间并提高设计灵活性。本实施例中可以同时使用多端子多电容器结构110和多端子多电容器结构210,因此进一步减少了空间的占用,提高了设计灵活性。

第一端子212a、第二端子212b和接地端子212c可以类似于图1B所示的第一端子112a、第二端子112b和接地端子112c,在此不再赘述。

图3是根据本发明的一些实施例的半导体封装结构300的截面图。需要说明的是,半导体封装结构300可包括与图1所示的半导体封装结构100相同或相似的元件,为简单起见,不再赘述。在以下实施例中,电容器设置在背面重分布层上,以在正面重分布层上保留更多的导电端子。正面重分布层可以是设置在晶粒具有导电焊盘的一端的重分布层。

虽然在图3中示出了两个半导体晶粒,第一半导体晶粒312和第二半导体晶粒306,但是可以存在一个或多于两个的半导体晶粒。例如,第一封装结构300a可以包括垂直堆叠的三个半导体晶粒。或者,第一封装结构300a可以包括四个半导体晶粒,其中两个半导体晶粒垂直堆叠在半导体晶粒上方,并且另一个半导体晶粒布置在半导体晶粒上方并且与两个半导体晶粒相邻。
在一些实施例中,第一封装结构300a还包括与第一半导体晶粒312和/或第二半导体晶粒306相邻的一个或多个无源部件(未示出),例如电阻器、电容器、电感器等,或其组合。
在一些实施例中,第二半导体晶粒306包括多个通孔308,其电耦接到正面重分布层302。通孔308可以由金属形成,例如铜、钨等、或其组合。如图3所示,通孔308可以具有基本上垂直的侧壁并且可以从第二半导体晶粒306的顶面延伸到第二半导体晶粒306的底面,但是本发明不限于此。通孔308可以具有其他配置和其他数量。
在一些实施例中,第一半导体晶粒312包括多个通孔314,其电耦接到背面重分布层324。通孔314可以由金属形成,例如铜、钨等,或其组合。如图3所示,通孔314可以具有基本上垂直的侧壁并且可以从第一半导体晶粒312的顶面延伸到第一半导体晶粒312的底面,但是本发明不限于此。通孔314可以具有其他配置和数量。

在其他一些实施例中,电容310为多电容器结构,如图1所示的多端子多电容器结构110,在此不再赘述。在这些实施例中,电容器310可以通过正面重分布层302和第二半导体晶粒306中的通孔308电耦接到第一半导体晶粒312,并且可以通过正面重分布电耦接到第二半导体晶粒306。
如图3所示,根据一些实施例,第一封装结构300a包括围绕第一半导体晶粒312的模制材料(或模塑料)316。模制材料316可以覆盖第二半导体晶粒306的顶面(或上表面)并且可以邻接第一半导体晶粒312的侧壁。模制材料316可以保护第一半导体晶粒312免受环境影响,从而防止第一半导体晶粒312由于例如应力、化学品和/或湿气而损坏。
模制材料316可以包括非导电材料,例如可模制聚合物、环氧树脂、树脂等,或它们的组合。在一些实施例中,模制材料316以液体或半液体形式施加,然后通过任何合适的固化过程固化,固化过程例如包括热固化过程、UV固化过程等,或其组合。模制材料316可以用模具(未示出)成形或模制。
然后,可以通过平坦化制程例如化学机械抛光(chemical mechanicalpolishing,CMP)部分地去除模制材料316,直到暴露第一半导体晶粒312的顶面。在一些实施例中,模制材料316的顶面和第一半导体晶粒312的顶面基本上共面。如图3所示,模制材料316的侧壁可以与第二半导体晶粒306的侧壁基本共面。

图中所示的导电柱318的配置仅是示例性的,并不旨在限制本发明。例如,在第一半导体晶粒312和第二半导体晶粒306的相对侧上,导电柱318的数量可以不同。或者,导电柱318可以设置在第一半导体晶粒312和第二半导体晶粒306的一侧上。
如图3所示,根据一些实施例,第一封装结构300a包括围绕第一半导体晶粒312、第二半导体晶粒306、模制材料316和导电柱318的模制材料322。模制材料322可以邻接第二半导体晶粒306的侧壁和模制材料316,并且可以覆盖正面重分布层302的顶面和背面重分布层324的底面(下表面)。
如图3所示,模制材料322可以填充导电柱318之间以及第一半导体晶粒312和第二半导体晶粒306与导电柱318之间的间隙。模制材料322可以保护半导体晶粒312、第二半导体晶粒306和导电柱318免受环境影响,从而防止这些部件由于例如应力、化学制品和/或湿气而损坏。
在一些实施例中,模制材料322包括非导电材料,例如可模制聚合物、环氧树脂、树脂等,或它们的组合。在一些实施例中,模制材料322以液体或半液体形式施加,然后通过任何合适的固化过程固化,例如热固化过程、UV固化过程等,或其组合。模制材料322可以用模具(未示出)成形或模制。
然后,可以通过诸如化学机械抛光(CMP)的平坦化制程部分地去除模制材料322,直到暴露导电柱318的顶面。在一些实施例中,模制材料322的顶面和导电柱318的顶面基本上共面。如图3所示,模制材料322的侧壁可以与正面重分布层302的侧壁和背侧重分布层324的侧壁基本共面。在一些其他实施例中,可以省略模制材料316,并且模制材料322可以邻接第一半导体晶粒312的侧壁。

与具有焊盘侧电容(电容器位于晶粒的焊盘的一侧或附近)的半导体封装结构相比,根据本发明的半导体封装结构300具有不占用导电端子304空间的电容器320,可以增加设计的灵活性。电容器320设置在模制材料322内可以节省空间的占用,利用第一半导体晶粒312与导电柱318之间间隙来布置电容器320,充分利用了闲置空间,提高了空间利用率。
在其他一些实施例中,电容器320为多电容器结构,例如为如图1所示的多端子多电容器结构110,在此不再赘述。在这些实施例中,电容器320可以电耦接到第一半导体晶粒312,并且还可以通过第一半导体晶粒312中的端子320t、背面重分布层324、通孔314以及第二半导体晶粒306中的通孔308电耦接到第二半导体晶粒306。
在电容器310是电耦接第一半导体晶粒312和第二半导体晶粒306的多电容器结构的实施例中,可以省略电容器320。类似地,在电容器320是电耦接第一半导体晶粒312和第二半导体晶粒306的多电容器结构的实施例中,电容器310可以用导电端子304代替。
或者,在一些实施例中,电容器310和电容器320中的至少一个是多电容器结构,并且第一封装结构300a可以包括两个以上的半导体晶粒,该半导体晶粒可以电耦接到电容器310和电容器320。
如图3所示,根据一些实施例,第二封装结构300b设置在第一封装结构300a上方并且通过多个导电端子326电耦接到背面重分布层324。导电端子326可由导电材料形成,例如金属。在一些实施例中,导电端子326包括微凸块、受控塌陷芯片连接(C4)凸块、焊球、球栅阵列(BGA)球等或其组合。

基板328的布线结构可以设置在金属间介电(IMD)层中。在一些实施例中,IMD层可以由有机材料形成,例如聚合物基础材料,非有机材料,例如氮化硅、氧化硅、氮氧化硅等,或它们的组合。可以在基板328中和基板328上形成任何期望的半导体部件。然而,为了简化图示,仅示出了平坦基板328。
如图3所示,根据一些实施例,第二封装结构300b包括设置在基板328上方的半导体部件330。半导体部件330可包括相同或不同的装置。例如,半导体部件330可以包括诸如动态随机接入存储器(DRAM)的存储器晶粒。在一些实施例中,第二封装结构300b还包括一个或多个无源元件(未示出),例如电阻器、电容器、电感器等或其组合。

如图4所示,根据一些实施例,第一半导体晶粒312包括多个通孔402,其电耦接到背面重分布层324。通孔402可以类似于图3所示的通孔314,在此不再赘述。
如图4所示,根据一些实施例,第一封装结构300a包括设置在背面重分布层324上方的电容器410。电容器320可以设置在背面重分布层324和第二封装结构300b之间。如图4所示,电容器410可以具有多个端子410t,并且可以通过端子410t、背面重分布层324和第一半导体晶粒312中的通孔402电耦接到第一半导体晶粒312。
在其他一些实施例中,电容(器)410为多电容器结构,如图1所示的多端子多电容器结构110,在此不再赘述。在这些实施例中,电容器410可以电耦接到第一半导体晶粒312,并且还可以通过端子410t、背面重分布层324、通孔402和通孔308电耦接到第二半导体晶粒306。本实施例中的电容器410的设置可以形成额外的散热路径,帮助第一半导体晶粒312、第二半导体晶粒306、半导体部件330的散热。例如第一半导体晶粒312和第二半导体晶粒306的热量可以通过通孔402、端子410t传递到电容器410,半导体部件330的热量可以通过基板328传递到电容410,然后电容器410将热量散发到外界。因此本实施例中电容器410的布置方式还提高了散热效率。
在电容器310是电耦接第一半导体晶粒312和第二半导体晶粒306的多电容器结构的实施例中,可以省略电容器410。类似地,在电容器410为电耦接第一半导体晶粒312和第二半导体晶粒306的多电容器结构中的实施例中,电容器310可以用导电端子304代替。
或者,在一些实施例中,电容器310和电容器410中的至少一个是多电容器结构,并且第一封装结构300a可以包括两个以上的半导体晶粒,其可以电耦接到电容器310和电容器410。
在一些实施例中,半导体封装结构300中的电容器310和电容器320可以垂直堆叠。类似地,在一些实施例中,半导体封装结构400中的电容器310和电容器410可以垂直堆叠。堆叠电容器可以被称为多电容器结构,并且将在与图5A和5B相关的描述中讨论。
