可以理解,这里描述的各种示例性实施例的特征可以相互组合,除非另有特别说明。
现在参考附图描述实施例,其中通常用相似的参考符号表示相同的元件。在下面的描述中,出于解释的目的,设定了具体的数字以便提供对一个或者多个实施例的全面了解。然而,本领域的技术人员很清楚,可以使用更具体的细节来实现一个或者多个实施例。在其它的例子中,以示意性的形式描述了公知的结构和元件,以便简化描述一个或者多个实施例。因此下面的描述不是出于限制性目的,其范围由权利要求书来限定。
用于制造至少一个器件的方法的实施例,用于制造半导体芯片组件的方法的实施例和用于半导体芯片封装的实施例可以使用多种类型的半导体芯片或者半导体衬底,其中包括逻辑集成电路,模拟集成电路,混合信号集成电路,传感器电路,MEMS(微机电系统),功率集成电路,具有集成的无源元件的芯片。
在多个实施例中,将多个层或者堆层应用到彼此上,或者涂覆或沉积材料到层上。可以理解,例如术语“涂覆”或者“沉积”的意思是完全覆盖了将多层涂覆到彼此上的所有技术。在一个实施例中,它们的意思是覆盖技术,其中将多层作为整体一次涂覆,例如叠置技术和将多层顺序沉积的技术,例如溅射、电镀、模制、CVD等。
半导体芯片可以包括在它们的外表面的一个或多个上的接触元件或接触垫,其中接触元件用于电接触半导体芯片。可以使用任何导电材料来制造接触元件,例如使用铝、金或者铜的材料,或者使用合金材料,或者使用导电的有机材料、或者使用导电的半导体材料。
在多个实施例中,半导体芯片可以被材料层覆盖。材料层的材料可以是任何电绝缘材料,例如任何种类的模塑材料,任何种类的环氧树脂材料,或者任何种类的树脂材料。在用材料层覆盖半导体芯片的过程中,“嵌入的芯片”能被制造。嵌入的芯片可以具有标准半导体晶片的形式,并且通常被称为“重构晶片”或者“再造晶片”。然而,可以了解,嵌入的晶片不受限于晶片的形式和形状,而且可以具有任意的尺寸和形状和任何适合的嵌入有半导体芯片的阵列。
图1示出了制造至少一个器件的方法的实施例的流程图。该方法包括将至少一个半导体芯片施加到第一成形元件上(S1),施加至少一个元件到第二成形元件上(S2),和施加材料到该至少一个半导体芯片和该至少一个元件上(S3)。
将被制造的器件可以是例如中间产品或者成品。例如,该器件可以是半导体芯片模块,例如是嵌入的晶片或重构晶片或再造晶片形式。例如,该器件还可以是通过将半导体芯片模块分成多个半导体芯片封装而得到的半导体芯片封装。
根据一个实施例,施加到第二成形元件上的元件可以是其它半导体芯片,通路元件,电阻器,线圈,层,金属层,箔片,金属箔片,铜箔片,引线框架,焊料球,夹具,接触元件,或者接触垫。
根据另一个实施例,该至少一个半导体芯片可以被施加到承载层上,在一个实施例中被施加到第一承载层上,其接着被施加到第一成形元件。单独的,至少一个元件可以被施加到承载层上,在一个实施例中是第二承载层,其接着被施加到第二成形元件。该至少一个半导体芯片可以被施加到第一承载层的主表面上,该至少一个元件可以被施加到第二承载层的主表面上,在施加材料之前,将第一和第二承载层相对彼此定位,以使得第一和第二承载层的主表面彼此面对。
根据另一个实施例,施加材料层包括模塑,在一个实施例中是传递模塑或者压缩模塑。更具体的,在传递模塑中通过将材料引入到通过第一成形元件和第二成形元件形成的空腔中来施加材料到至少一个半导体芯片上和至少一个元件上。更具体的,在压缩模塑中通过将材料压入到第一成形元件和第二成形元件之间来将材料施加到至少一个半导体芯片上和至少一个元件上。
根据另一个实施例,提供模塑装置,该模塑装置具有下模塑工具和上模塑工具,半导体芯片或者第一承载层被放置到该下模塑工具上,和元件或第二承载层被放置到该上模塑工具上,并且将模塑材料填满在下模塑工具和上模塑工具之间的中间空间中。在一个实施例中,低和上模塑工具相对于彼此被定位,以使得它们形成内部空腔,该内部空腔包含半导体芯片和元件,以及第一和第二承载层(如果存在的话),并且将模塑材料充满该内部空腔。
根据另一个实施例,多个第一半导体芯片被施加到第一成形元件上和多个第二半导体芯片被施加到第二成形元件上。第一半导体元件的数目等于或者不等于第二半导体芯片的数目。
根据另一个实施例,第一半导体芯片和第二半导体芯片可以被施加为多个第一半导体芯片中的一个或者多个和多个第二半导体芯片中的一个或者多个可以是彼此相对地放置到要被制造的器件中,该器件可以是例如半导体芯片模块。
根据另一个实施例,第一和第二半导体芯片被施加为第一半导体芯片中的一个或者多个和第二半导体芯片中的一个或者多个可以是并排交替的方式被放置。
图2A-I示出了连同处理设备一起的中间产品和器件的横截面图,用于说明制造至少一个器件的方法的另一个实施例。
在图2A中示出了第一承载层1的实施例的横截面图。该第一承载层1例如是有任何结构的材料制成,例如是金属、塑料、陶瓷、或者硅、或者聚合物材料。它能够是例如刚性构造,使得它是稳定和可持的。因此它可以具有不小于200μm的厚度。
图2B示出了中间产品的横截面图,其中粘附性箔片2已经被叠置到第一承载层1上,该粘附性箔片2能够具有双面粘附性并且能够从第一承载层1去除掉,或者从它被施加到的任何其它层或者材料上被去除掉。
该第一承载层1可以用做释放层。在一个实施例中,其可包括释放系统,使得当外部预定条件,例如加热或者UV辐射,该粘附性箔片2从第一层1中被去除掉。可以从第一承载层1的侧面施加加热或者UV辐射,使得在粘附性箔片2是热释放箔片的情况中,该第一承载层1不需要是光学透明的,而在粘附性箔片2是UV辐射释放带的情况中,该第一承载层1对于UV辐射是光学透明的。
图2C示出了另一个中间产品的横截面图,其中半导体芯片3被放置在粘附性箔片2上,该半导体芯片3经受了测试,并且按顺序放置。然后,使用常规的拾取和放置机器来将多个半导体芯片3放置到粘附性箔片2上。该多个半导体芯片3的每一个包括至少一个接触垫3A,其中多个接触垫3A被放置到半导体芯片3的与粘附层2面对的表面上。该半导体芯片3被放置为具有充分的空间以允许分散电接触,如后面将要详细介绍的。
图2D示出了如在图2C中示出的中间产品的横截面图,其已经被放置到模塑装置的底部工具4中。该模塑装置的底部工具4能够具有包括空腔的盒子的形状和结构。
图2E示出了操作中的模塑装置的横截面图。图的底部示出了底部工具4,如在图2D中已经介绍的。图的上部示出了模塑装置的顶部工具5。顶部工具5承载了与图2C中所示相同的布置。该另一个布置包括具有其上施加了粘附层7的第二承载层6和附着到粘附层7的第二半导体芯片8。该第二半导体芯片8被定位成当第二承载层6施加到顶部工具5时该第二半导体芯片8与第一半导体芯片3横向错开,该顶部工具5连接到底部工具4以便制造半导体芯片模块。通过使用真空机构将第二承载层6固定到顶部工具5,其原理对于常规的晶片夹具是已知的。
在图2F中,示出了如图2E所示的模塑装置的横截面图。另外,其还示出了如何都将模制介质9填充到底部工具4的空腔中。通过使用分配嘴10来填充该模制介质9,该分配嘴延伸通过在底部工具4和顶部工具5之间的开口。这里使用的模塑技术可以是传递模塑技术或者压缩模塑技术。可能的模塑材料包括例如脂肪族和芳族聚合物,包括热塑性塑料和热固性的聚合物和这些聚合物的混合物,并且还可以包括其它类型的聚合物。
在图2G中,示出了如图2E和2F中已经示出的模塑装置的横截面图。另外,在图2G中示出了如何将顶部工具5向下移动以便固定连接到底部工具4。在该操作中,当通过向下移动第二半导体芯片8和第二承载层6的主表面来使模制介质9位移时,该模制介质9被压缩和分配。符号ΔT表示附加的预定量的加热被施加到底部工具4和顶部工具5上。
在图2H中,示出了顶部工具5固定连接到底部工具4中并且模制介质9沿着第一承载层1和第二承载层6的整个长度被分配,和该模制介质9覆盖了第一半导体芯片3和第二半导体芯片8以及第一承载层1和第二承载层6相互面对的主表面上。
之后,进行固化工艺以便使得模制介质9变硬,使得它成为刚性材料层。在图2I中,示出了在固化工艺之后,顶部工具5从底部工具4脱离开的情况。在这里没有示出的其它工艺中,被固化和硬化的模塑层9从底部工具4中被去除掉,和第一承载层1和第二承载层6从具有其中嵌入了第一半导体芯片3和第二半导体芯片8的固化和硬化的模塑层9中去叠置。

图3A示出了第一半导体芯片3和第二半导体芯片8以并排交替的方式布置的实施例。在该实施例中,该模塑材料层9相对薄,因为在模塑材料层9的横向位置处存在最大仅一个半导体芯片,即或者是第一半导体芯片3或者是第二半导体芯片8。
在图3B中,示出了第一导体芯片3和第二半导体芯片8彼此相对放置的实施例。在该实施例中,模塑材料层9相对厚,因为存在模塑材料层9的多个横向位置,其中两个半导体芯片即第一半导体芯片3和第二半导体芯片8直接相互堆叠。
在图3A和3B的实施例中,第一半导体芯片3的数目等于第二半导体芯片8的数目。在图3C中,示出了第一半导体芯片3的数目不同于第二半导体芯片8_1,8_2的数目的实施例。在一个实施例中,在图3C示出的实施例中,第二半导体芯片8_1,8_2的数目是第一半导体芯片3的数目的两倍。更具体的,在图3C的实施例中,两个第二半导体芯片8_1,8_2放置在第一半导体芯片3的每一个上面。

也可以在施加模塑材料层5到半导体芯片23和28之间之前,放置电通路连接。因此聚合物或者金属(例如铜)的导电柱、焊料球或栏或者其它导电材料可以被放置到半导体芯片23和28之间,例如通过在模塑之前将它们连接到承载层1或6之一。然后将通路连接连同半导体芯片23和28一起嵌入到模塑化合物。通过背面研磨通路连接的顶部,能够将其从模塑材料中被清除掉和暴露出,并且然后被用作在布置到模塑材料层5的任一侧上的多个半导体芯片之间的通路接连。
根据图5D,将电介质层24和26沉积到材料层29的下表面和上表面。通过使用旋转涂覆技术将电介质层24和26沉积到材料层29的下表面和上表面。在电介质层24和25中,在接触垫23A和28A以及电通路连接29B处形成开口。

在图5F中,示出了施加焊料停止层或者焊料保护层32之后的结构。在施加焊料停止层32之后,在焊料停止层32中形成开口以使得对该再分配垫27A、27B进行开口。之后,将焊料球33填充到焊料停止层32的开口中。
注意,图5A的半导体芯片模块的其它部分以如上所述的相同的方式被制造。在最后的工艺中,半导体芯片模块20被分开为多个半导体芯片封装,例如图5F所示。

图7B示出了制造半导体芯片组件50。
