参照图1和图2,半导体器件可以包括第一半导体芯片100和第二半导体芯片200。第二半导体芯片200堆叠在第一半导体芯片100上,并且可以物理地电连接到第一半导体芯片100。
第一半导体芯片100可以包括第一衬底102、第一电路层110和第一结合层140。第一衬底102可以包括硅、硅锗、碳化硅、氧化硅或其组合。
第一电路层110可以包括第一元件层120和第一互连层130。第一元件层120可以包括内部线121、层间绝缘层125、接触C1和栅极结构TR1。内部线121可以设置在第一元件层120中以电连接到第一互连层130。栅极结构TR1可以设置在第一衬底102的上表面上。第一衬底102可以在其上表面上包括杂质区。杂质区可以设置在栅极结构TR1的两侧。内部线121可以通过接触C1电连接到杂质区。层间绝缘层125可以在内部线121、接触C1和栅极结构TR1上延伸,或者覆盖内部线121、接触C1和栅极结构TR1。如本文所用,覆盖另一元件或表面的元件可以部分地或完全地覆盖该另一元件或表面。内部线121和接触C1可以包括钨、钴、铜或铝。虽然未示出,但是第一元件层120还可以包括覆盖内部线121和接触C1的阻挡膜。层间绝缘层125可以包括氧化硅、氮化硅、氮氧化硅或其组合。

第一半导体芯片100和第二半导体芯片200可以是不同类型的半导体芯片,即,第一半导体芯片100和第二半导体芯片200可以是包括不同结构和配置的半导体芯片。在一些实施例中,第一半导体芯片100可以是逻辑芯片,第二半导体芯片200可以是包括逻辑芯片100中不存在的存储结构(例如,位线、字线等)的存储芯片。在一些实施例中,第一半导体芯片100可以是逻辑芯片,第二半导体芯片200可以是包括逻辑芯片100中不存在的像素结构(例如,光电转换区域)的像素阵列芯片。在一些实施例中,第一半导体芯片100和第二半导体芯片200可以是相同类型的半导体芯片。
参照图2和图3,第一结合层140和第二结合层240可以沿着结合界面或表面S彼此结合。第一结合层140可以包括第一界面绝缘层142、层间绝缘层144和结合结构150。第一结合层140还可以包括阻挡膜146和内部通路V1、V2和V3。

层间绝缘层144可以位于第一界面绝缘层142的下方,并且可以覆盖结合结构150和内部通路V1、V2和V3。层间绝缘层144可以保护结合结构150和内部通路V1、V2和V3并使他们电绝缘。阻挡膜146可以覆盖结合结构150的侧表面和下表面。阻挡膜146也可以设置在内部通路V1、V2和V3以及内部线131和132的侧表面上。

结合结构150可以包括结合焊盘BP和互连L1。结合焊盘BP被例示为具有圆形形状,但不限于此,并且可以具有多边形或四边形形状、具有圆角的多边形或四边形形状等。互连L1可以连接结合焊盘BP和内部通路V1、V2和V3。在一些实施例中,互连L1可以形成为当从上方观察时穿过结合焊盘BP。在一些实施例中,互连L1可以连接到结合焊盘BP的一侧。结合焊盘BP和互连L1可以通过镶嵌工艺形成。在一些实施例中,在形成内部通路V1、V2和V3之后,可以通过单镶嵌工艺形成结合焊盘BP和互连L1。阻挡膜146也可以设置在互连L1与内部通路V1、V2和V3之间。在一些实施例中,结合焊盘BP、互连L1和内部通路V1、V2和V3可以通过双镶嵌工艺形成。
在一些实施例中,内部通路V1、V2和V3可以在横向方向上与结合焊盘BP间隔开,并且可以设置在互连L1的下方。在一些实施例中,内部通路V1、V2和V3可以设置在结合焊盘BP的下方。图3例示了互连L1连接到多个内部通路V1、V2和V3,但是在一些实施例中,互连L1可以连接到更少的内部通路或一个内部通路。在平面图中,互连L1的宽度W1可以小于结合焊盘BP的宽度W2。结合焊盘BP的宽度W2可以在约0.2μm至约2.5μm的范围内。
结合焊盘BP、互连L1和内部通路V1、V2和V3可以包括金属。在一些实施例中,结合焊盘BP、互连L1和内部通路V1、V2和V3可以包括Cu、Al、Co或其组合。阻挡膜146可以包括TaN、Ta、Ti、TiN、Mn、MnN或其组合。可以在结合焊盘BP和互连L1上设置包括Mn、Co、Ru、Sn、CoWP、Au、Pt、Ni或其组合的膜。
第二结合层240可以包括第二界面绝缘层242、层间绝缘层244和结合焊盘BP'。第二结合层240还可以包括阻挡膜246。第二界面绝缘层242可以包括与第一界面绝缘层142相同的材料,并且层间绝缘层244可以包括与层间绝缘层144相同的材料。结合焊盘BP'可以包括与结合焊盘BP相同的材料。第一界面绝缘层142和第二界面绝缘层242可以设置在结合表面S上,以增加第一半导体芯片100与第二半导体芯片200之间的附着。例如,第二界面绝缘层242可以设置在第二结合层240的下表面上,并且第二界面绝缘层242可以在层间绝缘层244上延伸。另外,第二界面绝缘层242可以防止不与结合焊盘BP'接触的互连L1的金属材料扩散到层间绝缘层244中。
结合焊盘BP可以结合到结合焊盘BP'。互连L1可以设置在第一结合层140的上表面上以执行布线(routing)。例如,结合到结合焊盘BP'的结合焊盘BP可以通过互连L1电连接到一个或更多个内部通路。结合焊盘BP可以通过互连L1电连接到内部通路V1、V2和V3。因此,结合焊盘BP可以电连接到不同的内部线131和132。图3例示了结合结构150包括在第一结合层140中,但是实施例不限于此。在一些实施例中,类似地,可以在第二结合层240的下表面上设置包括互连的结合结构。
如图1至图3所例示,结合焊盘BP和互连L1设置在第一半导体芯片100的第一结合层140的结合表面S上,因此可以在结合表面S上执行结合功能和互连功能。即使当结合焊盘BP和结合焊盘BP'未对准(例如,沿着结合表面S偏离期望的重叠)而彼此结合时,可以通过互连L1确保接触区域,从而降低结合风险。由于结合焊盘BP和结合焊盘BP'未被配置为用于一对一结合,所以第一半导体芯片100和第二半导体芯片200可以以结合焊盘BP和互连L1的各种图案彼此结合。
图4例示了根据示例实施例的半导体器件的第一结合层和第二结合层的平面图。
参照图4,第一结合层140a可以包括结合结构150a。在平面图中,互连L1可以具有突出部分。在一些实施例中,在平面图中,突出部分的宽度W3可以大于互连L1的宽度W1。突出部分不连接到结合焊盘BP',并且可以被称为非结合焊盘NBP1、NBP2和NBP3。非结合焊盘NBP1、NBP2和NBP3可以通过双镶嵌工艺与结合焊盘BP和互连L1一起形成。在一些实施例中,在平面图中,非结合焊盘NBP的宽度W3可以小于结合焊盘BP的宽度W2。
第二结合层240a可以包括结合焊盘BP'。结合焊盘BP'可以连接到结合焊盘BP。在平面图中,结合焊盘BP'的宽度W4可以不同于结合焊盘BP的宽度W2。在一些实施例中,结合焊盘BP'的宽度W4可以大于结合焊盘BP的宽度W2。在一些实施例中,结合焊盘BP'的宽度W4可以小于结合焊盘BP的宽度W2。
图5和图6是根据示例实施例的半导体器件的横截面视图。
参照图5,半导体器件可以包括第一半导体芯片100和第二半导体芯片200b。在一些实施例中,第二半导体芯片200b可以是背部光接收图像传感器。第二半导体芯片200b可以包括光电转换部或区域PD、钝化层250、色彩滤光片252和微透镜254。光电转换部PD可以设置在第二衬底202的内部。钝化层250可以设置在第二衬底202上。色彩滤光片252和微透镜254可以设置在钝化层250上。

钝化层250可以包括氧化硅、氮化硅、氮氧化硅或其他绝缘材料。色彩滤光片252和微透镜254可以包括聚合材料。在一些实施例中,钝化层250可以包括抗反射层。
多个色彩滤光片252可以以包括针对每个单位像素的红色滤光片R、绿色滤光片G或蓝色滤光片B的拜耳图案来实现。可见区域的波长中的红色区域的波长可以穿过红色滤光片R。可见区域的波长中的绿色区域的波长可以穿过绿色滤光片G。可见区域的波长中的蓝色区域的波长可以穿过蓝色滤光片B。在一些实施例中,多个色彩滤光片252可以包括青色滤光片、品红色滤光片或黄色滤光片。多个色彩滤光片252还可以包括白色滤光片。

尽管未示出,但是第二半导体芯片200c还可以包括覆盖穿硅通路TSV1的阻挡膜。顶焊盘TP和穿硅通路TSV1和TSV2可以包括Cu、CuSn、CuMg、CuNi、CuZn、CuPd、CuAu、CuRe、CuW、W或其组合。覆盖穿硅通路TSV1的阻挡膜可以包括选自W、WN、WC、Ti、TiN、Ta、TaN、Ru、Co、Mn、WN、Ni或NiB中的至少一种材料。阻挡膜可以是单个膜或多个膜。

图12和图13是根据示例实施例的半导体器件的第一结合层和第二结合层的平面图。
参照图12,第一结合层140g可以包括结合结构150g。第二结合层240g可以包括结合焊盘BP'。结合结构150g可以包括结合焊盘BP和互连L1。互连L1可以连接结合焊盘BP和内部通路V1、V2和V3。互连L1可以具有各种形状以连接内部通路V1、V2和V3。例如,互连L1可以根据要连接的内部通路V1、V2和V3的位置而具有各种形状。在一些实施例中,互连L1可以具有折线形状。在一些实施例中,互连L1可以是沿对角线方向延伸或弯曲的线的形式。

参照图14,第一结合层140i可以包括多个结合结构150i。每个结合结构150i可以包括结合焊盘BP、非结合焊盘NBP和互连L。第二结合层240i可以包括多个结合焊盘BP'。每个结合焊盘BP可以通过互连L连接到非结合焊盘NBP中的一个非结合焊盘。非结合焊盘NBP可以电连接到第一结合层140i下方的内部线。
参照图15,第一结合层140j可以包括互连L1。第二结合层240j可以包括结合焊盘BP1和BP2。内部通路V1、V2和V3可以结合到结合焊盘BP1和BP2。内部通路V1、V2和V3可以电连接到第一结合层140j下方的内部线。第一结合层140j和第二结合层240j可以以各种图案彼此结合。在一些实施例中,互连L1可以连接到内部通路V1、V2和V3。在一些实施例中,互连L1可以连接到多个内部通路中的一个或更多个内部通路,例如一个内部通路V1或两个内部通路V1和V2。结合焊盘BP1可以连接到一个内部通路V1,并且结合焊盘BP2可以连接到两个内部通路V2和V3。如图15所例示,第一结合层140j包括具有互连功能的互连L1,因此可以应用各种结合图案。
参照图16,第一结合层140k可以包括互连L1。第二结合层240k可以包括互连L1'。内部通路V1、V2和V3可以电连接到第一结合层140k下方的内部线。内部通路V4和V5可以电连接到第二结合层240k上的内部线。在平面图中,互连L1和互连L1'可以延伸成彼此相交,即,相交。在一些实施例中,互连L1和互连L1'可以在对角线方向或相同方向上延伸。如图16所例示,第一结合层140k和第二结合层240k通过互连L1和互连L1'连接,因此可以提高结合位置和图案的自由度。另外,即使当互连L1和互连L1'未对准(例如,沿着结合表面S)而彼此接触时,也可以保持他们之间一定的接触面积。
图17和图18是根据示例实施例的半导体器件的横截面视图。参照图17,第二结合层240l可以设置在第一结合层140l上。结合焊盘BP和结合焊盘BP'可以形成为在横向方向上具有相同的宽度,并且可以在横向方向上彼此对准和结合。第一结合层140l可以包括覆盖焊盘BP'的侧表面和下表面的阻挡膜146l。第二结合层240l可以包括覆盖焊盘BP的侧表面和上表面的阻挡膜246l。

在一些实施例中,可以通过化学机械抛光(CMP)部分地去除结合焊盘BP和BP'的表面的边缘,因此结合焊盘BP和BP'可以具有圆角。结合焊盘BP'上的阻挡膜146l的一部分可以不附着到结合焊盘BP,因此可以与结合焊盘BP'分离。类似地,阻挡膜246l的一部分可以与结合焊盘BP分离。
在一些实施例中,可以在结合焊盘BP与结合焊盘BP'之间形成金属氧化物。金属氧化物可以通过氧化结合焊盘BP和BP'形成,并且可以包括例如氧化铜(如CuO)。
参照图18,第一结合层140m可以包括覆盖结合焊盘BP'的侧表面和下表面的阻挡膜146m。第二结合层240m可以包括覆盖结合焊盘BP的侧表面和上表面的阻挡膜246m。结合焊盘BP和结合焊盘BP'可以彼此不对准。在一些实施例中,结合焊盘BP和结合焊盘BP'可以在沿着结合表面S的横向方向上未对准并彼此结合。结合焊盘BP'的一部分可以与界面氧化物层148或阻挡膜246m接触。
根据本发明构思的示例实施例,在半导体器件的结合层的结合界面处提供结合焊盘和互连,因此,可以减少用于互连的层的数量并且可以实施各种类型的结合结构。
尽管已经参照附图描述了本发明构思的实施例,但是本领域技术人员应当理解的是,在不脱离本发明构思的范围且不改变本发明构思的基本特征的情况下,可以进行各种修改。因此,上述实施例应当仅被认为是描述性的,而不是为了限制的目的,本发明构思的范围在所附权利要求中阐述。
