参照图4B,半导体封装1000a可以包括下再分布结构600、半导体封装10a、下模制层710、下连接结构720和上再分布结构800。由于图4B中示出的半导体封装1000a的各个构造类似于图4A中示出的半导体封装1000的相应各个构造,并且已经参照图3描述了半导体封装10a,所以省略了对半导体封装1000a的描述。半导体封装10a可以被称为半导体封装1000a的子半导体封装。
图5显示了根据一实施方式的半导体封装2000的截面图。
参照图5,半导体封装2000可以包括下再分布结构600、半导体封装10、下模制层710、下连接结构720、上再分布结构800、上半导体芯片1110和上模制层1130。下再分布结构600、半导体封装10、下模制层710、下连接结构720和上再分布结构800类似于参照图4A描述的半导体封装1000的相应各个构造,以下描述集中在差异上。此外,半导体封装2000在图5中示出为包括参照图1描述的半导体封装10,但是不限于此,并且还可以包括参照图3描述的半导体封装10a。
上半导体芯片1110可以设置在上再分布结构800上。在一实施方式中,上半导体芯片1110可以是存储器芯片或逻辑芯片。在一实施方式中,第一半导体芯片210(见图1)和第二半导体芯片410(见图1)可以是逻辑芯片,上半导体芯片1110可以是存储器芯片。例如,第一半导体芯片210和第二半导体芯片410可以是CPU芯片,上半导体芯片1110可以是DRAM芯片。半导体封装2000在图5中示出为包括一个上半导体芯片1110,但是不限于此,并且还可以包括多个上半导体芯片1110。
上连接端子1120可以布置在上半导体芯片1110和上再分布结构800之间。上连接端子1120可以将上半导体芯片1110物理和电地连接到上再分布结构800。
上模制层1130可以覆盖上半导体芯片1110的至少一部分。具体地,上模制层1130可以沿着上半导体芯片1110的下表面和相对的侧壁延伸,并且覆盖上半导体芯片1110的下表面和相对的侧壁。上模制层1130的上表面和上半导体芯片1110的上表面可以共面。然而,不限于此,与图5所示不同,上模制层1130可以覆盖上半导体芯片1110的上表面。在一实施方式中,上模制层1130可以由与选自下模制层710、第一模制层230和第二模制层430中的至少一种的材料不同的材料制成。例如,上模制层1130可以由与第二模制层430的材料不同的材料制成,并且可以是与第一模制层230和下模制层710的材料相同的材料。
图6A至图6G显示了根据一实施方式的制造半导体封装10的方法中各个步骤的截面图。
参照图6A,首先可以提供第一载体基板C1。例如,第一载体基板C1可以是但不限于半导体基板、玻璃基板、陶瓷基板或塑料基板。在提供第一载体基板C1之后,可以在第一载体基板C1上形成第一再分布结构100。此时,第一再分布绝缘层130(见图2B)可以通过层压工艺形成,第一再分布图案120(见图2B)可以通过镀覆工艺形成。例如,在形成第一再分布结构100的步骤中,可以重复形成第一再分布线123、形成覆盖第一再分布线的第一再分布绝缘层130、在第一再分布绝缘层130处形成通路孔以及形成填充通路孔的第一再分布通路121的工序。在形成第一再分布结构100之后,第一连接结构240可以形成在第一再分布结构100上。第一连接结构240可以例如通过形成籽晶层并使用籽晶层执行电镀工艺来形成。
参照图6B,在图6A的结果中,具有分布结构213和贯通电极217且具有其上设置有第二连接结构250的上表面的第一半导体芯片210可以安装在第一再分布结构100上。第一半导体芯片210可以通过第一连接端子220安装在第一再分布结构100上。由于第一连接端子220联接到第一再分布焊盘110和第一芯片焊盘211,所以第一半导体芯片210可以固定在第一再分布结构100上。此时,第一半导体芯片210可以被安装成使得第一半导体芯片210的第一无源表面215Sb面对第一再分布结构100。
参照图6C,在图6B的结果中,第一模制层230可以形成在第一再分布结构100上。此时,第一模制层230可以覆盖第一半导体芯片210的上表面、下表面和相对的侧壁。在形成第一模制层230之后,可以对第一模制层230执行平坦化工艺。因为执行了平坦化工艺,所以第一模制层230的上表面可以变得与第一连接结构240的上表面和第二连接结构250的上表面共面。
参照图6D,第二再分布结构300可以形成在已经对其执行了平坦化工艺的第一模制层230上。第二再分布结构300可以以与参照图6A描述的第一再分布结构100的形成相同的方式形成。在形成第二再分布结构300之后,第二半导体芯片410可以安装在第二再分布结构300上。第二半导体芯片410可以通过第二连接端子420安装到第二再分布结构300。因为第二连接端子420联接到第二再分布焊盘310和第二芯片焊盘411,第二半导体芯片410可以被固定在第二再分布结构300上。此时,第二半导体芯片410可以被安装成使得第二半导体芯片410的第二有源表面413Sa面对第二再分布结构300。
参照图6E,在图6D的结果中,可以在第二再分布结构300上形成第二模制层430。此时,第二模制层430可以覆盖第二半导体芯片410的下表面和相对的侧壁。在形成第二模制层430之后,可以对第二模制层430执行平坦化工艺。因为执行了平坦化工艺行,第二模制层430的上表面可以变得与第二半导体芯片410的上表面共面。由于第二模制层430通过与用于第一模制层230的工艺不同的工艺形成,所以第一模制层230和第二模制层430可以由不同的材料制成。在一实施方式中,当制造参照图3描述的半导体封装10a时,在形成第二模制层430之前,可以首先形成底部填充层450(见图3)以填充第二半导体芯片410和第二再分布结构300之间的间隙。
参照图6F,在图6E的结果中,可以在第二半导体芯片410和第二模制层430上形成金属层440。具体地,在第一金属层441形成在第二半导体芯片410和第二模制层430上之后,第二金属层443可以形成在第一金属层441上。第一金属层441可以通过沉积工艺例如物理气相沉积(PVD)形成。第二金属层443可以通过经由沉积工艺在第一金属层441上形成籽晶层并使用籽晶层执行电镀工艺来形成。在一实施方式中,第一金属层441可以包括Ti,第二金属层443可以包括Cu。在一实施方式中,金属层440可以形成为完全覆盖第二半导体芯片410的上表面和第二模制层430的上表面。
参照图6G,在图6F的结果中,可以在金属层440的上表面上附接第二载体基板C2。第二载体基板C2可以与第一载体基板C1基本相同或相似。在附接第二载体基板C2之后,可以从第一再分布结构100的下表面去除第一载体基板C1。在去除第一载体基板C1之后,可以在第一再分布结构100的下表面上形成外部连接端子500。
此后,在图6G的结果中,由于可以去除第二载体基板C2,所以可以制得图1中所示的半导体封装10。
在根据一实施方式的半导体封装10中,可以使用第一载体基板C1安装第一半导体芯片210,然后可以单独安装第二半导体芯片410。因此,只有好的管芯可以被选择以安装为第一半导体芯片210或第二半导体芯片410。因此,在使用第二半导体芯片410作为基板通过晶片上芯片(COW)方案安装第一半导体芯片210时,在第二半导体芯片410是不良管芯的情况下执行的附加工艺(例如,虚设芯片安装工艺等)可以被限制和/或防止执行,因此可以降低半导体封装10的制造成本。
图7A至图7D显示了根据一实施方式的制造半导体封装1000的方法中各个步骤的截面图。
参照图7A,首先可以提供第三载体基板C3。第三载体基板C3可以与第一载体基板C1相同或相似。在提供第三载体基板C3之后,可以在第三载体基板C3上形成下再分布结构600。下再分布结构600可以以与参照图6A描述的第一再分布结构100的形成相同的方式形成。在形成下再分布结构600之后,可以在下再分布结构600上形成下连接结构720。下连接结构720可以以与参照图6A描述的第一连接结构240的形成相同的方式形成。
参照图7B,在图7A的结果中,可以安装半导体封装10。半导体封装10可以通过外部连接端子500(见图1)安装到下再分布结构600。由于外部连接端子500联接到下再分布焊盘610和UBM层140(见图1),所以半导体封装10可以被固定在下再分布结构600上。
参照图7C,在图7B的结果中,可以在下再分布结构600上形成下模制层710。此时,下模制层710可以覆盖半导体封装10的下表面和相对的侧壁。在形成下模制层710之后,可以对下模制层710执行平坦化工艺。因为执行了平坦化工艺,所以下模制层710的上表面可以变得与半导体封装10的上表面共面。在一实施方式中,下模制层710可以由与从第一模制层230(见图1)和第二模制层430(见图1)中选择的至少一种的材料不同的材料制成。
参照图7D,在图7C的结果中,可以在半导体封装10和下模制层710上形成上再分布结构800。上再分布结构800可以以与参照图6A描述的第一再分布结构100的形成相同的方式形成。在形成上再分布结构800之后,可以在上再分布结构800上附接第四载体基板C4。第四载体基板C4可以与第一载体基板C1基本相同或相似。在附接第四载体基板C4之后,可以从下再分布结构600的下表面去除第三载体基板C3,并且可以在下再分布结构600的下表面上形成外部连接端子900。
此后,在图7D的结果中,去除第四载体基板C4,并且形成上再分布焊盘810,因此可以制造图4A和图4B中所示的半导体封装1000。
在一实施方式中,在图7A的结果中,也可以安装半导体封装10a,不同于图7B所示。此后,可以顺序执行参照图7C至图7D描述的工序,以制造图4B中所示的半导体封装1000a。
图8显示了根据一实施方式的制造半导体封装2000的方法的截面图。
参照图8,在图7D的结果中,在去除第四载体基板C4并制造图4A中所示的半导体封装1000之后,可以在上再分布结构800上安装上半导体芯片1110。上半导体芯片1110可以通过上连接端子1120安装到上再分布结构800。因此,上半导体芯片1110可以被固定在上再分布结构800上。
此后,在图8的结果中,上模制层1130可以形成在上再分布结构800上。此时,上模制层1130可以覆盖上半导体芯片1110的下表面和相对的侧壁。然而,不限于此,上模制层1130可以覆盖上半导体芯片1110的上表面、下表面和相对的侧壁。随着上模制层1130形成,可以制造图5中所示的半导体封装2000。
以上公开的一个或更多个元件可以包括或实施于处理电路中,诸如包括逻辑电路的硬件;硬件/软件组合,诸如执行软件的处理器;或它们的组合。例如,处理电路可以包括但不限于中央处理单元(CPU)、算术逻辑单元(ALU)、数字信号处理器、微型计算机、现场可编程门阵列(FPGA)、片上系统(SoC)、可编程逻辑单元、微处理器、专用集成电路(ASIC)等。
