技术领域
示例性实施例涉及半导体封装和制造半导体封装的方法。更具体地,示例性实施例涉及包括去耦电容器的多芯片封装和制造半导体封装的方法。
背景技术
在诸如eMCP(嵌入式多芯片封装)的多芯片封装中,可以安装去耦电容器以减少不期望的同时切换噪声(SSN)的影响,例如当多个输出驱动器在封装中同时切换时在配电中引起的压降。然而,安装在半导体封装中的常规大容量型电容器可能增加半导体封装的整体厚度和面积,并且连接到电容器的布线可能增加电感,从而降低半导体封装的可靠性。
发明内容
示例性实施例提供了一种半导体封装,其能够减小半导体封装的整体尺寸并改善半导体封装的电性能。
在一些实施例中,本公开涉及一种半导体封装,包括:封装基板,具有上表面和下表面,并且包括形成在上表面上的多个基板焊盘;电容器结构,布置在封装基板的上表面上,并且包括半导体基板和形成在半导体基板的上部区域中的至少一个去耦电容器;多个第一半导体芯片,安装在封装基板上,并且由电容器结构支撑;第一导电连接构件,将第一半导体芯片的芯片焊盘电连接到所述多个基板焊盘;以及第二导电连接构件,将去耦电容器的电容器焊盘电连接到所述多个基板焊盘。
在一些实施例中,本公开涉及一种半导体封装,包括:封装基板;第一半导体芯片,安装在封装基板上;电容器结构,以与第一半导体芯片间隔开的方式布置在封装基板上,并且包括半导体基板和形成在半导体基板的上表面中的至少一个去耦电容器;多个第二半导体芯片,安装在封装基板上并由电容器结构支撑;以及导电连接构件,将去耦电容器的电容器焊盘电连接到封装基板的基板焊盘。

具体实施方式
将理解,当提及元件“连接”或“耦接”到另一元件或在另一元件“之上”时,该元件可以直接连接或耦接到该另一元件或直接在该另一元件之上,或者可以存在介于中间的元件。相比之下,当提及元件“直接连接”、“直接耦接”到另一元件或“直接在”另一元件“之上”时,不存在介于中间的元件。用于描述元件之间的关系的其他词语应以类似的方式来解释(例如,“在……之间”与“直接在……之间”、“相邻”与“直接相邻”等)。然而,除非上下文另有指示,否则如本文所使用的术语“接触”是指连接接触(即触摸)。
当涉及朝向、布局、位置、形状、尺寸、量或其他度量时本文所用术语(例如,“相同”、“相等”、“平面”或“共面”)不必表示完全相同的朝向、布局、位置、形状、尺寸、量或其他度量,而是意在包含例如在由于制造工艺而可能发生的可接受变化内的几乎相同的朝向、布局、位置、形状、尺寸、量或其他度量。除非上下文或其他陈述另有说明,否则术语“基本上”在本文中可以用于强调该含义。例如,被描述为“基本上相同”、“基本上相等”或“基本上平面”的项可以是完全相同、相等或平面的,或者可以在例如由于制造工艺而可能发生的可接受变化内是相同、相等或平面的。
诸如“约”或“大致”等的术语可以反映仅以小的相对方式和/或以不显著改变某些元件的操作、功能或结构的方式变化的量、尺寸、取向或布局。例如,“约0.1至约1”的范围可以包括诸如在0.1附近的0%-5%偏差和在1附近的0%至5%偏差的范围,尤其是如果这种偏差维持与所列出的范围相同的效果。
如本文所使用的,被描述为“电连接”的项被配置为使得电信号可以从一个项传递到另一个项。因此,物理连接到无源电绝缘组件(例如,印刷电路板的预浸料层、连接两个器件的电绝缘粘合剂、电绝缘的底部填充物或模具层等)的无源导电组件(例如,导线、焊盘、内部电线等)不与该组件电连接。此外,彼此“直接电连接”的项通过一个或多个无源元件(例如,导线、焊盘、内部电线、通孔等)电连接。因此,直接电连接的组件不包括通过有源元件(诸如晶体管或二极管)电连接的组件。本文描述的各种焊盘可以连接到与之相连的器件内的内部电路,并且可以发送去往和/或来自它们所附接到的器件的信号和/或电压。
本文描述的半导体器件被具体实现为电子器件,例如半导体存储芯片或半导体逻辑芯片、这种芯片的堆叠、包括封装基板和一个或多个半导体芯片的半导体封装、堆叠式封装器件、或半导体存储模块。本文描述的半导体器件可以被具体实现为易失性存储器或非易失性存储器。包括这种半导体器件的芯片或封装通常也可以被称为半导体器件。
图1是示出了根据示例性实施例的半导体封装的截面图。图2是示出了图1中的半导体封装的平面图。图3是示出了图1中的半导体封装的电容器结构的平面图。图4至图6是示出了图3中的电容器结构的各种类型的硅芯片电容器的截面图。
参考图1至图6,半导体封装100可以包括封装基板110、第一半导体芯片200、具有去耦电容器320的电容器结构300、多个第二半导体芯片400、多个第三半导体芯片500、多个第四半导体芯片600和模制构件700。半导体封装100还可包括多个导电连接构件230、330、430、530、630,其被配置为将第一半导体芯片200、第二半导体芯片400、第三半导体芯片500、第四半导体芯片600和去耦电容器320中的至少一个电连接到封装基板110。
在示例性实施例中,封装基板110可以是具有彼此相对的上表面112和下表面114的基板。例如,封装基板110可以包括印刷电路板(PCB)、柔性基板、带基板等。印刷电路板可以包括其中具有通孔和各种电路元件的多电路板。
多个布线160、162和连接到布线160、162的基板焊盘120可以布置在封装基板110的上表面112上。布线160、162可以在封装基板110的上表面112上延伸。布线160、162可以具有在封装基板110的上表面112上延伸的环形形状。例如,布线160、162可以在上表面112上形成闭环,从而对与布线160、162相连的元件进行电连接。基板焊盘120可以连接到布线160、162的相应端部。例如,布线160、162的至少一部分可以用作基板焊盘120,从而形成着陆焊盘(landing pad)。布线160、162可以包括作为用于向安装在封装基板110上的电气组件供电的电力网的电源布线或接地布线。基板焊盘120可以包括连接到电源布线或接地布线的电源焊盘或接地焊盘。
虽然图中未示出,但是封装基板110还可以包括用于将数据信号传送到电气组件的基板信号布线和基板信号焊盘。另外,虽然示出了一些基板焊盘,但是基板焊盘的数量和位置是示例性示出的,因此可以不限于此。应当理解,为了简洁起见,在图中未示出基板信号焊盘和布线以及基板焊盘,并且将省略关于上述元件的说明。
第一绝缘层140可以形成在封装基板110的上表面112上,以覆盖布线160、162并露出基板焊盘120。第一绝缘层140可以覆盖封装基板110的除了基板焊盘120之外的整个上表面112。例如,第一绝缘层140可以包括阻焊剂。

第四半导体芯片600a、600b、600c和600d可以通过粘合构件640a、640b、640c和640d粘附到电容器结构300上。因此,第四半导体芯片600a、600b、600c和600d可以安装在半导体基板10上并由电容器结构300支撑。第四半导体芯片600a、600b、600c和600d可以顺序地相互偏移或以锯齿形的方式相互偏移。堆叠的第四半导体芯片600的面积可以大于第一半导体芯片200或电容器结构300的面积。例如,当从上到下观察时,各个第四半导体芯片600的面积(例如,长度×宽度)可以大于第一半导体芯片200和电容器结构300的组合面积。
然后,可以执行布线接合工艺,以将第四半导体芯片600a、600b、600c和600d的芯片焊盘连接到半导体基板10的上表面12上的基板焊盘120。第四半导体芯片600a、600b、600c和600d的芯片焊盘602可以通过第五导电连接构件630连接到基板焊盘120。
参考图11,可以在半导体基板10上形成模制构件700以覆盖第一半导体芯片200、电容器结构300、第二半导体芯片400、第三半导体芯片500和第四半导体芯片600。例如,可以通过模制工艺在基板10上形成模制构件700,以覆盖第一半导体芯片200、电容器结构300、第二半导体芯片400、第三半导体芯片500和第四半导体芯片600。模制构件700可以包括环氧树脂模塑料(EMC)。然后,当在半导体基板10的下表面14上的外部连接焊盘130上设置外部连接构件800之后,可以通过锯切工艺将基板10切割成单独的半导体封装。
图12是示出了根据示例性实施例的半导体封装的电容器结构的平面图。图13是示出了图12中的半导体封装的封装基板的平面图。除了电容器结构的去耦电容器之间的连接关系之外,该半导体封装可以与参考图1至图6所述的半导体封装基本相同或相似。因此,相同的附图标记将用于指代相同或相似的元件,并且将省略关于上述元件的任何进一步的重复说明。
参考图12和图13,电容器结构300可以包括第一去耦电容器至第四去耦电容器320a、320b、320c和320d。第一去耦电容器至第四去耦电容器320a、320b、320c和320d的电容器焊盘302可以通过接合线电连接到封装基板110的基板焊盘120。
在一些实施例中,第一去耦电容器320a的电容器焊盘302可以通过封装基板110的基板焊盘120和布线160、162电连接到第四半导体芯片600。因此,第一去耦电容器320a可以为第四半导体芯片600提供去耦功能。
第二去耦电容器320b的电容器焊盘302可以通过封装基板110的基板焊盘120和布线160、162电连接到第一半导体芯片200。因此,第二去耦电容器320b可以为第一半导体芯片200提供去耦功能。
第三去耦电容器320c的电容器焊盘302可以通过封装基板110的基板焊盘120和布线160、162电连接到第三半导体芯片500。因此,第三去耦电容器320c可以为第三半导体芯片500提供去耦功能。
第四去耦电容器320d的电容器焊盘302可以通过封装基板110的基板焊盘120和布线160、162电连接到第二半导体芯片400。因此,第四去耦电容器320d可以为第二半导体芯片400提供去耦功能。
电容器结构300可以包括多个去耦电容器320,因此可以在预定尺寸内提供每个半导体芯片所需的期望电容。例如,包括多个去耦电容器320(每个去耦电容器320具有预定尺寸(例如,长度和宽度))的电容器结构300可以为半导体芯片200、400、500和600中的每一个提供期望的电容。
图14是示出了根据示例性实施例的半导体封装的电容器结构的平面图。图15是示出了图14中的半导体封装的封装基板的平面图。除了电容器结构的去耦电容器之间的连接关系之外,该半导体封装可以与参考图1至图6所述的半导体封装基本相同或相似。因此,相同的附图标记将用于指代相同或相似的元件,并且将省略关于上述元件的任何进一步的重复说明。
参考图14和图15,电容器结构300可以包括第一去耦电容器至第四去耦电容器320a、320b、320c和320d。第一去耦电容器至第四去耦电容器320a、320b、320c和320d中的第一去耦电容器的电容器焊盘302可以通过接合线电连接到封装基板110的基板焊盘120。
在一些实施例中,第一去耦电容器320a的电容器焊盘302可以通过封装基板110的基板焊盘120和布线160、162电连接到第四半导体芯片600。因此,第一去耦电容器320a可以为第四半导体芯片600提供去耦功能。
其余的第二去耦电容器至第四去耦电容器320b、320c和320d的电容器焊盘302可以不电连接到封装基板的基板焊盘120。
因此,电容器结构300可以为其上的半导体芯片提供相对宽的支撑区域,并且可以仅为半导体芯片中所选择的半导体芯片提供去耦功能。例如,虽然去耦电容器中仅一个(例如,第一去耦电容器320a)可以提供去耦功能,但是第一去耦电容器至第四去耦电容器320a、320b、320c和320d可以提供物理上支撑形成在其上的一个或多个半导体芯片的结构。
图16是示出了根据示例性实施例的半导体封装的平面图。除了电容器结构之外,该半导体封装可以与参考图1至图6所述的半导体封装基本相同或相似。因此,相同的附图标记将用于指代相同或相似的元件,并且将省略关于上述元件的任何进一步的重复说明。
参考图16,电容器结构300的面积可以是图1中的电容器结构的面积的大约两倍。电容器结构300可以包括八个去耦电容器。在一些实施例中,可以通过晶片锯切工艺形成电容器结构300以包括两个芯片电容器。例如,在电容器结构300包括两个芯片电容器的实施例中,第一芯片电容器可以包括第一去耦电容器至第四去耦电容器,并且第二芯片电容器可以包括第五去耦电容器至第八去耦电容器。可以通过锯切工艺来确定电容器结构300的面积。面积为该面积的两倍的电容器结构300可以用于支撑相对更宽的半导体芯片。
因此,可以调节电容器结构的面积以支撑更大的支撑区域。
图17是示出了根据示例性实施例的半导体封装的截面图。图18是示出了图17中的半导体封装的封装基板上的电容器结构和第一半导体芯片的截面图。图19是示出了图18中的电容器结构的平面图。除了多个电容器结构之外,该半导体封装可以与参考图1至图6所述的半导体封装基本相同或相似。因此,相同的附图标记将用于指代相同或相似的元件,并且将省略关于上述元件的任何进一步的重复说明。
参考图17至图19,半导体封装101可以包括封装基板110、第一半导体芯片200、第一电容器结构300a和第二电容器结构300b、多个第二半导体芯片400和模制构件500。

第一电容器结构300a可以包括第一半导体基板310a和形成在第一半导体基板310a的上表面中的第一电容器320a。第二电容器结构300b可以包括第二半导体基板310b和形成在第二半导体基板310b的上表面中的第二电容器320b。例如,第一电容器结构300a和第二电容器结构300b可以是通过晶片锯切工艺切割的相同的单独结构。
第一电容器结构300a的厚度T1可以与第二电容器结构300b的厚度T2相同或不同。例如,第一电容器结构300a沿第三方向D3的高度可以与第二电容器结构300b沿第三方向D3的高度相同或不同。因此,可以将多个电容器结构300a和300b堆叠在彼此上以用作具有期望高度的支撑构件(例如,包括第一电容器结构300a和第二电容器结构300b以及粘合构件340a和340b的组合高度)。
第一电容器结构300a可以通过第二导电连接构件330电连接到封装基板110。第一电容器结构300a的第一电容器320a的电容器焊盘302可以通过第二导电连接构件330电连接到封装基板110的基板焊盘。第二电容器结构300b可以通过第二导电连接构件330电连接到封装基板110。第二电容器结构300b的第二电容器320b的电容器焊盘302可以通过第二导电连接构件330电连接到封装基板110的基板焊盘。

图20是示出了根据示例性实施例的半导体封装的截面图。除了电容器结构的布置之外,该半导体封装可以与参考图1至图6所述的半导体封装基本相同或相似。因此,相同的附图标记将用于指代相同或相似的元件,并且将省略关于上述元件的任何进一步的重复说明。
