第一再分布图案130可以将第一半导体芯片110的焊盘110p电连接到外部连接端子190。另外,第一再分布图案130可以电连接到第二再分布图案230。通过第一再分布图案130和第二再分布图案230,第一半导体芯片110和第二半导体芯片210可以彼此电连接,并且第二半导体芯片210可以电连接到外部连接端子190。
更详细而言,第一再分布图案130可以由多个子再分布图案来形成,并且子再分布图案可以具有多层结构。例如,第一再分布图案130可以包括第一子再分布图案131和第二子再分布图案133。第一子再分布图案131可以形成在第一封装层120上,并且可以连接到第一半导体芯片110的焊盘110p。第一子再分布图案131的一部分可以通过第一封装层120和第二绝缘图案240被连接到第二再分布图案230。第二子再分布图案133在第一绝缘图案140上延伸,并且可以通过第一绝缘图案140被连接到第一子再分布图案131。

第二封装200可以布置在第一封装100上。第二封装200可以包括第二半导体芯片210。第二半导体芯片210可以包括焊盘210p。第二半导体芯片210可以是一个半导体芯片。然而,本发明构思不限于此。例如,第二半导体芯片210可以是多个半导体芯片的堆叠体。
在示例性实施例中,第二半导体芯片210可以是例如存储器半导体芯片。可替代地,在示例性实施例中,第二半导体芯片210可以是逻辑芯片。

根据本发明构思的实施例,第二封装200与第一封装100之间的电连接可以通过第一再分布图案130和第二再分布图案230来执行。由于半导体封装10不包括诸如焊球的、用于将第二封装200连接到第一封装100的封装间连接端子,因此可以简化半导体封装制造工艺并且可以制造出更薄的PoP型半导体封装。
通常,在堆叠有多个封装的PoP型半导体封装的情况下,由于半导体封装的翘曲,所以会在封装间连接端子中产生诸如裂缝的损坏,因此半导体封装的可靠性劣化。然而,根据本发明构思的示例性实施例,由于第二封装200和第一封装100可以在没有易于受到翘曲影响的封装间连接端子的情况下电连接,所以可以提高半导体封装10的可靠性。
图2A至图2D是示出根据本发明构思的示例性实施例的制造半导体封装的方法的剖视图。在图2A至图2D中,将对制造图1所示的半导体封装10的方法进行描述。

参考图2C,可以在第一封装层120和第一半导体芯片110上形成第一再分布结构。为了形成第一再分布结构,可以顺序地形成第一子再分布图案131、第一绝缘图案140和第二子再分布图案133。更详细而言,第一子再分布图案131形成在第一封装层120上,与第一半导体芯片110的焊盘110p接触,并且沿着第一封装层120的通孔120H延伸,并且可以与第二再分布模式230接触。例如,第一子再分布图案131可以通过种子层形成工艺、掩模工艺和电镀工艺来形成。在形成第一子再分布图案131之后,为了形成第一绝缘图案140,在第一封装层120和第一子再分布图案131上形成绝缘层,并且将绝缘层的一部分去除,从而可以形成用于将第一子再分布图案131的一部分暴露的开口。在形成第一绝缘图案140之后,可以在第一绝缘图案140上形成第二子再分布图案133。第二子再分布图案133可以通过第一绝缘图案140被连接到第一子再分布图案131。例如,第二子再分布图案133可以通过种子层形成工艺、掩模工艺和电镀工艺来形成。
然后,在第一绝缘图案140上形成保护层150。保护层150可以具有将第二子再分布图案133的一部分暴露的开口。在形成保护层150之后,可以将外部连接端子190附接到通过保护层150的开口而暴露的第二子再分布图案133。外部连接端子190可以是例如焊球或凸块。

参考图9,半导体封装10f可以包括下部封装610以及上部封装620。由于下部封装610可以具有与图8A和8B所示的半导体封装10e相同的组件,并且上部封装620可以具有与图7所示的半导体封装10d相同的组件,因此将不给出下部封装610和上部封装620的详细描述。
如图9所示,设置在下部封装610中的第一子再分布图案431可以穿过下部封装610的封装层420、以及导热膜380延伸,并且可以连接到下部导电层370。也就是说,下部封装610的半导体芯片411和上部封装620的半导体芯片311、321、331和341可以通过下部封装610的再分布图案430、上部封装620的下部导电层370、以及上部封装620的第一再分布图案313、第二再分布图案323、第三再分布图案333和第四再分布图案343被连接。
在示例性实施例中,下部封装610的半导体芯片411是AI处理器,并且上部封装620的半导体芯片311、321、331和341可以是存储器半导体芯片,该存储器半导体芯片被配置为向下部封装610的半导体芯片411发送电信号并且从下部封装610的半导体芯片411接收电信号。
在本发明构思的示例性实施例中,由于下部封装610和上部封装620可以在没有易于受到翘曲影响的封装间连接端子的情况下彼此电连接,因此可以提高半导体封装10f的可靠性。另外,由于可以在没有封装间连接端子的情况下堆叠多个封装,因此可以制造出更薄的半导体封装10f。
应当理解的是,本文所描述的实施例应仅被认为是描述性的,而并非为了限制的目的。每个实施例中的特征或方面的描述可通常应被认为可用于其他实施例中的其他类似特征或方面。
虽然已经参考附图描述了一个或多个实施例,但是本领域普通技术人员将会理解,在不脱离由所附权利要求限定的本公开的精神和范围的情况下,可以在形式和细节上进行各种修改。
