附图说明
当结合附图进行阅读时,从以下详细描述可最佳理解本发明的各个方面。应该指出,根据工业中的标准实践,各个部件未按比例绘制。实际上,为了清楚的讨论,各个部件的尺寸可以任意地增大或减小。
图1至图14示出了根据一些实施例的在用于形成封装的半导体器件的工艺期间的中间步骤的截面图。
图15至图20示出了根据一些实施例的在用于形成封装的半导体器件的工艺期间的中间步骤的截面图。
具体实施方式
以下公开内容提供了许多用于实现本发明的不同特征的不同实施例或实例。下面描述了组件和布置的具体实例以简化本发明。当然,这些仅仅是实例,而不旨在限制本发明。例如,以下描述中,在第二部件上方或者上形成第一部件可以包括第一部件和第二部件直接接触形成的实施例,并且也可以包括在第一部件和第二部件之间可以形成额外的部件,从而使得第一部件和第二部件可以不直接接触的实施例。此外,本发明可在各个实例中重复参考标号和/或字符。该重复是为了简单和清楚的目的,并且其本身不指示所讨论的各个实施例和/或配置之间的关系。
而且,为便于描述,在此可以使用诸如“在…之下”、“在…下方”、“下部”、“在…之上”、“上部”等空间相对术语,以描述如图所示的一个元件或部件与另一个(或另一些)元件或部件的关系。除了图中所示的方位外,空间相对术语旨在包括器件在使用或操作中的不同方位。器件可以以其他方式定向(旋转90度或在其他方位上),而在此使用的空间相对描述符可以同样地作出相应的解释。
各个实施例提供了改进的管芯堆叠结构以及包括该管芯堆叠结构的封装的半导体器件。可以通过在背侧再分布结构上形成第一导电柱来形成管芯堆叠结构;将包括第二导电柱的第一有源器件管芯附接至背侧再分布结构;以及将第二有源器件管芯附接至第一有源器件管芯。可以在第一导电柱、第二导电柱和第二有源器件管芯上方形成前侧再分布结构,并且封装组件可以附接至背侧再分布结构。使用该方法允许第一有源器件管芯、第二有源器件管芯和封装组件以最小的面积互连在封装的半导体器件中。而且,可以通过单个模制步骤和单个研磨步骤同时在第一有源器件管芯和第二有源器件管芯周围形成模塑料。任何一个第一和第二导电柱可以是椭圆形或圆形的,以减小封装的半导体器件中的应力。
图1至图14是根据一些实施例的在封装的半导体器件200的制造期间的中间阶段的截面图。图1示出了根据一些实施例的有源器件管芯50A。有源器件管芯50A将在后续工艺期间封装以形成集成电路封装件。在实施例中,有源器件管芯50A可以是片上系统(SoC)。在另外的实施例中,有源器件管芯50A可以是逻辑管芯(例如,中央处理单元(CPU)、图形处理单元(GPU)、应用处理器(AP)、微控制器等)、存储器管芯(例如,动态随机存取存储器(DRAM)管芯、静态随机存取存储器(SRAM)管芯、高带宽存储器(HBM)管芯等)、输入/输出(I/O)界面管芯、电源管理管芯(例如,电源管理集成电路(PMIC)管芯等)、射频(RF)管芯、传感器管芯、微机电系统(MEMS)管芯、信号处理管芯(例如,数字信号处理(DSP)管芯等)、前端管芯(例如,模拟前端(AFE)管芯等)等或它们的组合。在顶视图中,有源器件管芯50A可以具有从约9mm至约12mm的长度和在从约9mm至约12mm的宽度。
有源器件管芯50A可以形成在晶圆中,该晶圆可以包括在后续步骤中分割以形成多个有源器件管芯的不同的器件区域。可以根据适用的制造工艺来处理有源器件管芯50A以形成集成电路。例如,有源器件管芯50A包括半导体衬底52,诸如掺杂或未掺杂的硅或绝缘体上半导体(SOI)衬底的有源层。半导体衬底52可以包括其他半导体材料,诸如锗;化合物半导体,包括碳化硅、砷化镓、磷化镓、磷化铟、砷化铟和/或锑化铟;合金半导体,包括SiGe、GaAsP、AlInAs、AlGaAs、GaInAs、GaInP和/或GaInAsP;或它们的组合。也可以使用其他衬底,诸如多层或梯度衬底。半导体衬底52具有有源表面(例如,在图1中面向上的表面),有时被称为前侧;以及无源表面(例如,在图1中面向下的表面),有时被称为背侧。
器件54可以形成在半导体衬底52的前侧处。器件54可以是有源器件(例如,晶体管、二极管等)、电容器、电阻器等。在半导体衬底52的前侧上方形成层间电介质(ILD)56。ILD 56围绕并且可以覆盖器件54。ILD56可以包括由诸如磷硅酸盐玻璃(PSG)、硼硅酸盐玻璃(BSG)、硼掺杂磷硅酸盐玻璃(BPSG)、未掺杂硅酸盐玻璃(USG)等的材料形成的一个或多个介电层。
导电插塞58延伸穿过ILD 56,以电和物理地耦接器件54。例如,当器件54是晶体管时,导电插塞58可以耦接晶体管的栅极和源极/漏极区域。导电插塞58可以由钨、钴、镍、铜、银、金、铝等或它们的组合形成。在ILD 56和导电插塞58上方包括互连结构60。互连结构60将器件54互连以形成集成电路。互连结构60可以由,例如,ILD 56上的介电层中的金属化图案形成。金属化图案包括形成在一个或多个低k介电层中的金属线和通孔。互连结构60的金属化图案通过导电插塞58电耦接至器件54。
有源器件管芯50A还包括制成至外部连接的焊盘62,诸如铝焊盘。焊盘62位于有源器件管芯50A的有源侧上,诸如位于互连结构60中和/或上。一个或多个钝化膜64位于有源器件管芯50A上,诸如位于互连结构60和焊盘62的部分上。开口穿过钝化膜64延伸到焊盘62。管芯连接件66,诸如导电柱(例如,由诸如铜的金属形成),延伸穿过钝化膜64中的开口,并且物理和电耦接至相应的焊盘62。管芯连接件66可以通过例如镀等形成。管芯连接件66将有源器件管芯50A的相应集成电路电耦接。
可选地,可以在焊盘62上设置焊料区域(例如,焊球或焊料凸块)。焊球可以用于对有源器件管芯50A实施芯片探针(CP)测试。可以对有源器件管芯50A实施CP测试,以确定有源器件管芯50A是否是已知良好管芯(KGD)。因此,仅封装经受后续工艺的为KGD的有源器件管芯50A,并且不封装未通过CP测试的管芯。在测试之后,可以在随后的工艺步骤中去除焊料区域。
介电层68可以位于有源器件管芯50A的前侧上,诸如位于钝化膜64和管芯连接件66上。介电层68横向密封管芯连接件66,并且介电层68与有源器件管芯50A横向共末端。最初,介电层68可以掩埋管芯连接件66,从而使得介电层68的最上表面在管芯连接件66的最上表面之上。在焊料区域设置在管芯连接件66上的一些实施例中,介电层68也可以掩埋焊料区域。可选地,可以在形成介电层68之前去除焊料区域。
介电层68可以是聚合物,诸如PBO、聚酰亚胺、BCB等;氮化物,诸如氮化硅等;氧化物,诸如氧化硅、PSG、BSG、BPSG等;等,或它们的组合。介电层68可以例如通过旋涂、层压、CVD等形成。在一些实施例中,在有源器件管芯50A的形成期间,管芯连接件66通过介电层68暴露。在一些实施例中,管芯连接件66保持掩埋并且在后续工艺期间暴露,以用于封装有源器件管芯50A。暴露管芯连接件66可以去除管芯连接件66上可能存在的任何焊料区域。
在一些实施例中,有源器件管芯50A是包括多个半导体衬底52的堆叠器件。例如,有源器件管芯50A可以是包括多个存储器管芯的存储器器件,诸如混合存储立方体(HMC)模块、高带宽存储(HBM)模块等。在这样的实施例中,有源器件管芯50A包括通过衬底通孔(TSV)互连的多个半导体衬底52。每个半导体衬底52可以具有互连结构60。
