在一些在制造半导体封装之后移除载体110的替代性实施例中,还可使用剥离层(未示出)涂布载体110。举例来说,在载体110上设置剥离层,且所述剥离层的材料可为任何适合于将载体110与设置在载体110上的上方层(例如,缓冲层)或任何晶片接合及剥离的材料。在一些实施例中,剥离层可包括释放层(例如光热转换(“light-to-heat conversion,LTHC”)层)或胶粘层(例如紫外线可固化胶粘剂或热可固化胶粘层)。

在一些实施例中,如图1中所示,金属化层124设置在载体110之上且夹置在聚合物介电层122之间,其中金属化层124的顶表面的一些部分被聚合物介电层122的最顶层暴露出且金属化层124的底表面被聚合物介电层122的最底层覆盖。在一些实施例中,聚合物介电层122的材料可包括聚酰亚胺、环氧树脂、丙烯酸树脂、酚醛树脂、苯并环丁烯(benzocyclobutene,BCB)、聚苯并恶唑(polybenzoxazole,PBO)或任何其他适合的聚合物系介电材料,且可通过沉积形成聚合物介电层122。在一些实施例中,金属化层124的材料可包括铝、钛、铜、镍、钨及/或它们的合金,且可通过电镀或沉积来形成金属化层124。本发明实施例并非仅限于此。

在一些实施例中,通过光刻(photolithography)、镀覆、光刻胶剥除工艺(photoresist stripping process)或任何其他适合的方法形成穿孔130。在一个实施例中,可通过以下方式形成穿孔130:形成覆盖重布线路结构120的掩模图案(未示出),所述掩模图案具有开口以暴露出被聚合物介电层122的最顶层暴露出的金属化层124的顶表面;通过电镀或沉积形成填充所述开口的金属材料以形成穿孔130;以及接着移除掩模图案。在一个实施例中,穿孔130的材料可包括例如铜或铜合金等金属材料。然而,本发明实施例并非仅限于此。

一起参照图11及图12,在一些实施例中,通过混合结合(hybrid bonding)(通过混合结合界面IF)将半导体管芯400a及半导体管芯400b结合到设置在半导体衬底650上的内连线结构660。如图12中所示,举例来说,内连线结构660的一部分不被半导体管芯400a及半导体管芯400b覆盖。举例来说,混合结合工艺可包括亲水融合结合工艺(hydrophilicfusion bonding process)或疏水融合结合工艺(hydrophobic fusion bondingprocess)。在一个实施例中,执行亲水融合结合工艺,其中可工作结合温度(workablebonding temperature)近似范围为100℃到300℃且可工作结合压力(workable bondingpressure)近似大于1~5兆帕(MPa);然而,本发明实施例并不特别限定于此。参照图12,在一些实施例中,在半导体衬底650之上形成绝缘包封体630,其中半导体管芯400a及半导体管芯400b被包封在绝缘包封体630中,且被半导体管芯400a、400b暴露出的内连线结构660被绝缘包封体630覆盖。在一些实施例中,如图12中所示,半导体管芯400a及半导体管芯400b的侧壁被绝缘包封体630环绕及覆盖。在一些实施例中,绝缘包封体630可为氧化物(例如,氧化硅等)。在一些实施例中,可通过沉积形成绝缘包封体630。
继续基于图12,在一些实施例中,在绝缘包封体630中形成多个穿孔640。在一个实施例中,穿孔640的材料可包括例如铜或铜合金等金属材料。然而,本发明实施例并非仅限于此。在一些实施例中,所述形成穿孔640可包括将绝缘包封体630图案化以形成暴露出图案化导电层664的贯穿开口并在所述贯穿开口中填充导电材料以形成穿透绝缘包封体630且电连接到内连线结构660的穿孔640。举例来说,图案化工艺可包括激光钻孔工艺(laserdrilling process)或光刻工艺及刻蚀工艺。穿孔640的数目及大小并不限于图12,且可基于需求来选择。
举例来说,内连线结构660位于半导体衬底650与半导体管芯400a及400b之间、半导体衬底650与绝缘包封体630之间以及半导体衬底650与穿孔640之间,其中图案化导电层664的暴露出的最顶层分别支撑连接通孔450a、连接通孔450b及穿孔640。半导体衬底650通过图案化导电层664的最顶层、连接通孔450a及连接通孔450b结合到半导体管芯400a及半导体管芯400b,且内连线结构660电连接到半导体管芯400a、半导体管芯400b及穿孔640。
在一个实施例中,绝缘包封体630可对半导体管芯400a、400b进行包覆模塑且可能需要在形成穿孔640之前被平面化以暴露出半导体管芯400a的背侧表面410ab及半导体管芯400b的连接通孔450b的背侧表面410bb。在又一实施例中,可对绝缘包封体630、半导体管芯400a、400b及穿孔640执行平面化步骤,以使绝缘包封体630、半导体管芯400a、400b及穿孔640的表面相互共面;由此在绝缘包封体630、半导体管芯400a、400b及穿孔640之间获得高的共面性。在一些实施例中,平面化步骤可为研磨工艺或化学机械抛光(chemicalmechanical polishing,CMP)工艺。在平面化步骤之后,可可选地执行清洁步骤以例如清洁及移除从平面化步骤产生的残留物。然而,本发明实施例并非仅限于此,且可通过任何其他适合的方法执行平面化步骤。本发明实施例并非仅限于此。
参照图13,在一些实施例中,在绝缘包封体630上形成重布线路结构620,重布线路结构620包括一个聚合物介电层622及一个金属化层624;然而,本发明实施例并非仅限于此。重布线路结构620中所包括的金属化层624及聚合物介电层622的数目并非仅限于此。举例来说,金属化层624及聚合物介电层622的数目可为一个或多于一个。举例来说,聚合物介电层622的材料及形成可与图1中所述聚合物介电层122的材料及形成相同或相似,且金属化层624的材料及形成可与图1中所述金属化层124的材料及形成相同或相似,因此本文中可不再赘述。
继续基于图13,在一些实施例中,在重布线路结构620的金属化层624的暴露出的部分上形成接触接垫670。接触接垫670连接到重布线路结构620的金属化层624的暴露出的部分;且因此,接触接垫670通过重布线路结构620、穿孔640及内连线结构660电连接到半导体管芯400a及半导体管芯400b。举例来说,接触接垫670的材料可包括铝或铝合金。在一些实施例中,在重布线路结构620之上及接触接垫670上形成保护层680,其中保护层680包括多个开口以暴露出接触接垫670。
参照图14,在一些实施例中,在保护层680上形成连接通孔690且将连接通孔690实体连接到接触接垫670。换句话说,连接通孔690通过接触接垫670、重布线路结构620、穿孔640及内连线结构660电连接到半导体管芯400a及半导体管芯400b。在一些实施例中,依序执行切割(或单体化)工艺以将晶片切分成各别的且分离的芯片封装CP1,所述晶片具有连接在所述晶片之间的多个芯片封装CP1。在一个实施例中,所述切割工艺是包括机械刀片锯切(mechanical blade sawing)或激光切分(laser cutting)的晶片切割工艺。本发明实施例并非仅限于此。至此,芯片封装CP1的制造完成。在一些实施例中,在切割工艺期间,固持装置(未示出)适以在进行切割之前固定芯片封装CP1以防止由切割(或单体化)工艺造成的损害。举例来说,固持装置可为胶带(adhesive tape)、载体膜(carrier film)或吸持垫(suction pad)。
参照图2,在一些实施例中,通过倒装芯片结合(flip chip bonding)将芯片封装CP1结合到半导体管芯200及半导体管芯300。举例来说,芯片封装CP1实体连接到半导体管芯200及半导体管芯300,其中芯片封装CP1的连接通孔690分别实体连接到半导体管芯200的连接通孔234及半导体管芯300的连接通孔334。在一些实施例中,如图2中所示,芯片封装CP1在重布线路结构120与半导体管芯200的堆叠方向(例如,方向Z)(或称,重布线路结构120与半导体管芯300的堆叠方向)上与半导体管芯200及半导体管芯300交叠,且在重布线路结构120上的垂直投影从半导体管芯200延伸到半导体管芯300。应注意,半导体管芯200与半导体管芯300不沿堆叠方向(例如,方向Z)相互交叠而是沿侧向相互挨着进行排列。半导体管芯200及半导体管芯300通过芯片封装CP1相互电连通(electricallycommunicated)。由于所述配置,在半导体管芯200a、半导体管芯300a及芯片封装CP1(涉及其他半导体管芯400a、400b)之间实现了短的电路径(short electrical path),由此使其信号损失(signal loss)减少。
参照图3,在一些实施例中,在载体110之上(例如,在重布线路结构120上)形成绝缘包封体140以包封半导体管芯200、半导体管芯300、芯片封装CP1及穿孔130。换句话说,半导体管芯200、半导体管芯300、芯片封装CP1及穿孔130被绝缘包封体140覆盖且嵌置在绝缘包封体140中。在一些实施例中,绝缘包封体140为通过模塑工艺形成的模塑化合物(molding compound),且绝缘包封体140的材料可包括环氧树脂(epoxy resin)或其他适合的树脂。举例来说,绝缘包封体140可为含有化学填料的环氧树脂。
参照图3及图4,在一些实施例中,对绝缘包封体140及芯片封装CP1进行平面化直到暴露出芯片封装CP1的表面(例如,半导体衬底650的底表面650b)、连接通孔232的顶表面232t、连接通孔234的顶表面234t、连接通孔332的顶表面332t、连接通孔334的顶表面334t及穿孔130的顶表面130t为止。在对绝缘包封体140进行平面化之后,在载体110之上(例如,在重布线路结构120上)形成绝缘包封体140’。在绝缘包封体140的平面化工艺(示出在图4中)期间,也可对半导体管芯200的连接通孔232及连接通孔234及/或半导体管芯300的连接通孔332及连接通孔334进行平面化。在一些实施例中,如图4中所示,在绝缘包封体140及芯片封装CP1的平面化工艺期间,也可对穿孔130的一些部分进行平面化。举例来说,可通过机械研磨或CMP来形成绝缘包封体140’。在平面化工艺之后,可可选地执行清洁步骤以例如清洁及移除从平面化步骤产生的残留物。然而,本发明实施例并非仅限于此,且可通过任何其他适合的方法执行平面化步骤。
参照图5,在一些实施例中,在形成绝缘包封体140’之后,在平面化绝缘包封体140’上形成重布线路结构150。在一些实施例中,在绝缘包封体140’的顶表面140t、半导体衬底650的底表面650b、连接通孔232的顶表面232t、连接通孔332的顶表面332t及穿孔130的顶表面130t上形成重布线路结构150。即,在绝缘包封体140’上沿重布线路结构120与半导体管芯200的堆叠方向(例如,方向Z)(或称,重布线路结构120与半导体管芯300的堆叠方向)形成重布线路结构150。在一些实施例中,将重布线路结构150制作成与位于之下的一个或多个连接件电连接。此处,前述连接件可为半导体管芯200的连接通孔232、半导体管芯300的连接通孔332及嵌置在绝缘包封体140’中的穿孔130。换句话说,重布线路结构150电连接到半导体管芯200的连接通孔232、半导体管芯300的连接通孔332以及穿孔130。

在一些实施例中,金属化层154的最顶层可包括多个接垫。在此种实施例中,上述接垫可包括用于球安装的多个球下金属(under-ball metallurgy,UBM)图案154a。
然而,本发明实施例并非仅限于此。在替代性实施例中,金属化层154中的最顶金属化层154可包括用于球安装的多个UBM图案154a及/或用于安装其他半导体组件的多个连接接垫154b(参见图7),且根据本发明实施例,球下金属图案154a的数目及连接接垫154b的数目不受限制。
参照图6,在一些实施例中,在形成重布线路结构150之后,在球下金属图案154a上放置多个导电元件160。在一些实施例中,可通过植球工艺及/或回流工艺或其他适合的形成方法在球下金属图案154a上放置导电元件160。在一些实施例中,导电元件160可为球栅阵列封装(ball grid array,BGA)连接件、焊料球、金属柱、受控塌陷芯片连接(controlledcollapse chip connection,C4)凸块、微凸块、无电镀镍钯浸金技术(electrolessnickel-electroless palladium-immersion gold technique,ENEPIG)形成的凸块等。举例来说,导电元件160的材料可包括例如焊料、铜、铝、金、镍、银、钯、锡、类似材料或它们的组合等导电材料。在一个实施例中,举例来说,导电元件160的材料可为无焊料的(solder-free)。

继续参照图6,依序执行切割工艺以将在晶片中相连接的多个半导体封装SP1切分成各别的且分离的半导体封装SP1。在一个实施例中,所述切割工艺是包括机械刀片锯切或激光切分的晶片切割工艺。至此,半导体封装SP1的制造完成。在切割工艺期间,使用固持装置(未示出)以在切分具有多个半导体封装SP1的晶片之前固定所述晶片,以防止由依序的工艺或运输造成的损害。举例来说,固持装置可为胶带、载体膜或吸持垫。在又一实施例中,在切割工艺之后,可将载体110从半导体封装SP1剥离,其中重布线路结构120被暴露出;本发明实施例并非仅限于此。
图7是根据本发明实施例的一些示例性实施例的半导体封装的示意性剖视图。一起参照图6及图7,图6中所绘示的半导体封装SP1与图7中所绘示的半导体封装SP2相似;进而使得与上述元件相似或实质上相同的元件将使用相同的参考编号,且本文中将不再对所述相同元件及其关系(例如,相对定位配置及电连接)的一些细节或说明予以赘述。
一起参照图6及图7,不同在于,对于图1中所绘示半导体封装SP2,芯片封装CP1设置在重布线路结构150上且位于导电元件160旁边,其中半导体管芯200及半导体管芯300被半导体管芯200a及半导体管芯300a取代。举例来说,如图7中所示,半导体管芯200与半导体管芯200a之间的不同在于,半导体管芯200a包括连接通孔230的连接通孔232,连接通孔230中不包括连接通孔234;且半导体管芯300与半导体管芯300a之间的不同在于,半导体管芯300a包括连接通孔330的连接通孔332,连接通孔330中不包括连接通孔334。如图7中所示,芯片封装CP1通过重布线路结构150电连接到半导体管芯200a及半导体管芯300a,其中芯片封装CP1与半导体管芯200a及半导体管芯300a电连通(electrically communicated)。
在一些实施例中,如图7中所示,金属化层154中的最顶金属化层154包括用于球安装的多个UBM图案154a及用于安装其他半导体组件的多个连接接垫154b,且根据本发明实施例,球下金属图案154a的数目及连接接垫154b的数目不受限制。在一些实施例中,芯片封装CP1结合到连接接垫154b,且导电元件160中的一些导电元件160通过重布线路结构150及连接接垫154b电连接到芯片封装CP1。
如图7中所示,芯片封装CP1在重布线路结构120与半导体管芯200a的堆叠方向(例如,方向Z)(或称,重布线路结构120与半导体管芯300a的堆叠方向)上与半导体管芯200a及半导体管芯300a交叠,且在重布线路结构120上的垂直投影从半导体管芯200a延伸到半导体管芯300a。在一些实施例中,如在方向Z上测量,芯片封装CP1的高度小于导电元件160的高度。由于所述配置,在半导体管芯200a、半导体管芯300a及芯片封装CP1(涉及其他半导体管芯400a、400b)之间实现了短的电路径,由此使其信号损失减少。
图8是根据本发明实施例的一些示例性实施例的半导体封装的示意性剖视图。一起参照图6及图8,图6中所绘示的半导体封装SP1与图8中所绘示的半导体封装SP3相似;进而使得与上述元件相似或实质上相同的元件将使用相同的参考编号,且本文中将不再对所述相同元件及其关系(例如,相对定位配置及电连接)的一些细节或说明予以赘述。
一起参照图6及图8,不同在于,对于图8中所绘示半导体封装SP3,还包括附加元件(例如,介电层PM1、多个导通孔132、多个导通孔134及绝缘包封体142),其中芯片封装CP1设置在重布线路结构150与绝缘包封体140’之间,且半导体管芯200及半导体管芯300分别被半导体管芯200a及半导体管芯300a取代。举例来说,半导体管芯200与半导体管芯200a之间的不同在于,半导体管芯200a包括连接通孔230的连接通孔232,连接通孔230中不包括连接通孔234;且半导体管芯300与半导体管芯300a之间的不同在于,半导体管芯300a包括连接通孔330的连接通孔332,连接通孔330中不包括连接通孔334。
在一些实施例中,如图8中所示,介电层PM1形成在绝缘包封体140’上且实体地接触绝缘包封体140’,其中介电层PM1具有暴露出连接通孔232的顶表面、连接通孔332的顶表面及穿孔130的顶表面的多个开口。介电层PM1的材料可包括聚酰亚胺、PBO、BCB、例如氮化硅等氮化物、例如氧化硅等氧化物、PSG、BSG、BPSG或它们的组合等,介电层PM1可利用光刻工艺及/或刻蚀工艺而图案化。在一些实施例中,导通孔132及导通孔134形成在介电层PM1上且通过介电层PM1的开口连接到连接通孔232、332及穿孔130。导通孔132及导通孔134的材料及形成与图1中所述穿孔130的材料及形成相同或相似,因此本文中可不再赘述。

在一些实施例中,导通孔132、导通孔134及芯片封装CP1包封在绝缘包封体142中,且被导通孔132及导通孔134暴露出的介电层PM1被绝缘包封体142覆盖。如图8中所示,芯片封装CP1的底表面(例如,半导体衬底650的底表面650b)、导通孔132的顶表面132t及绝缘包封体142的顶表面142t实质上齐平。换句话说,芯片封装CP1的表面(例如,半导体衬底650的底表面650b)及导通孔132的顶表面132t与绝缘包封体142的顶表面142t实质上共面。在一些实施例中,重布线路结构150位于芯片封装CP1上,导通孔132及绝缘包封体142实体连接且电连接到导通孔132。绝缘包封体142的材料及形成与图3及图4中所述绝缘包封体140及绝缘包封体140’的材料及形成相同或相似,因此本文中可不再赘述。

一起参照图8及图9,不同在于,对于图9中所绘示半导体封装SP4,介电层PM1被以重布线路结构180取代。举例来说,所述形成重布线路结构180包括交替地依序形成一个或多个聚合物介电层182及一个或多个金属化层184。在一些实施例中,如图9中所示,重布线路结构180包括两个聚合物介电层182及夹置在所述两个聚合物介电层182之间的一个金属化层184;然而,本发明实施例并非仅限于此。由于聚合物介电层182及金属化层184的所述配置,因此为半导体封装SP4提供了布线功能。
重布线路结构180中所包括的金属化层及聚合物介电层的数目并非仅限于此。举例来说,金属化层及聚合物介电层的数目可为一个或多于一个。重布线路结构180的材料及形成与图1中所述重布线路结构120的材料及形成或图5中所述重布线路结构150的材料及形成相同或相似,因此本文中可不再赘述。
