Description

具硅穿孔连续型态的晶圆级晶片尺寸封装构造及制造方法
技术领域
本发明有关于半导体晶片封装领域,特别有关于一种具硅穿孔连续型态的晶圆级晶片尺寸封装构造及其制造方法,可适用于CMOS影像传感器晶片之封装应用。
背景技术
晶圆级晶片尺寸封装构造(Wafer Level Chip Scale Package, WLCSP)不同于传统的晶片封装方式,其先在整片晶圆上进行封装和测试,然后才切割成一个个包含IC颗粒的封装构造,并且半导体封装尺寸不大于晶片尺寸1.44倍的面积,有效地缩减半导体封装体积。通常晶圆级晶片尺寸封装构造具备双面纵向电性连接结构,以将外接端子接合于晶片底部,以缩小基板尺寸或省略基板构件。现有的双面纵向电性连接结构可为硅穿孔(Through Silicon Via, TSV),或可为晶侧重配置线路(chip side RDL),其中硅穿孔为较佳选择。
在其中一种使用硅穿孔的晶圆级晶片尺寸封装制程中,是针对复合式堆栈晶片进行封装作业,在晶圆阶段先组装成一体连接的多个复合式堆栈晶片,每一复合式堆栈晶片包含一体连接的装置晶片(device chip)以及载体晶片(carrier chip),接着使用激光或蚀刻方式进行钻孔以贯穿装置晶片以及载体晶片,再以铜、金镍铜合金、多晶硅、钨等导电材料填入孔洞,使复合式堆栈晶片达到双面纵向电性连接,由于不需要利用传统的打线方式使晶片电性连接至基板,不仅节省了基板的空间也减少了打线接合的制程。然而,此种结构在进行硅穿孔制程中的激光或蚀刻步骤时,不容易控制孔深度,常会发生孔洞的过度蚀刻(over-etching)与蚀刻不足(under-etching)的现象。当过度蚀刻,可能造成孔洞过深而穿透装置晶片上的焊垫,并使得蚀刻物质或蚀刻电浆扩散至晶片主动面,导致微电子组件的污染,并且容易产生晶片上的焊垫与孔洞内导电材料之间的电性连接失败的问题。当蚀刻不足,孔洞内导电材料将无法顺利连接到晶片上的焊垫。
发明内容

具体实施方式
下面结合附图和具体实施例对本发明作进一步说明,以使本领域的技术人员可以更好的理解本发明并能予以实施,但所举实施例不作为对本发明的限定。
依据本发明的第一具体实施例,一种具硅穿孔连续型态 晶圆级晶片尺寸封装构造100举例说明于图1的截面示意图。该晶圆级晶片尺寸封装构造100包含一装置晶片110、一载体晶片120、至少一间隔导体凸块130、一间隔黏合层140、一保护盖片150、至少一硅穿孔结构160、一保护层170以及多个外接端子180。
请参阅图1,该装置晶片110的主体具有一第一表面111与一第二表面112;通常该装置晶片110的主体为一半导体材料层,例如单晶硅,该装置晶片110的该第一表面111上可形成有一绝缘层116。其中一金属互连平行垫组合113嵌埋于该装置晶片110之中,至少一偏移垫114设置于该第一表面111并连接至该金属互连平行垫组合113;具体地,该金属互连平行垫组合113由多个金属垫M1、M2、M3所构成,该些金属垫M1、M2、M3相互平行且电性互连,可利用垫与垫之间的短栓柱达到电性互连;更具体地,该些金属垫M1、M2、M3的垫中心点可对准在一垂直中心线;该偏移垫114的材质可为铝(Al)、或铝铜合金(AlCu)。此外,一组件设置区115形成于该第一表面111;具体地,该组件设置区115为一影像感应组件区,可包含CMOS影像传感器的微镜结构;在不同实施例中,该组件设置区115可为一集成电路区或是一例如麦克风晶片传感器…等的微机电组件安装区。一表面介电层117可形成于该绝缘层116上,其中该绝缘层116作为该偏移垫114的底部周边绝缘层,该表面介电层117作为该偏移垫114的表面周边绝缘层。
该载体晶片120的主体具有一第三表面121与一第四表面122,该装置晶片110的该第二表面112贴合于该载体晶片120的该第三表面121。该载体晶片120的该第三表面121与该装置晶片110的该第二表面112之间可形成有一熔合结合层190,使得该装置晶片110与该载体晶片120之间为熔合结合(fusion bonding)。该装置晶片110与该载体晶片120的组合因其两者无热膨胀系数差异,将可避免在后续热处理制程之后产生应力剥离,或提高了耐用度等级。
该间隔导体凸块130接合于该偏移垫114上而突出于该第一表面111。在本实施例中,该间隔导体凸块130可包含一电镀金属块,其材质可包含金、银、铜及其合金,具体材质可为铜(Cu)或铜/镍/金(Cu/Ni/Au)的组合。此外,在一较佳型态中,一导体栓118可连接在该偏移垫114与该金属互连平行垫组合113之间,该间隔导体凸块130的表面覆盖面积可涵盖该导体栓118的形成位置,以使该导体栓118得到较佳的支撑与保护。
该间隔黏合层140形成于该装置晶片110的该第一表面111上,该间隔黏合层140包覆该间隔导体凸块130,以使该间隔导体凸块130不会曝露于大气环境而导致电气短路或干扰,借此控制该间隔导体凸块130只发挥对该硅穿孔结构160的电性连接与结构支撑的效果。具体地,该间隔黏合层140具有一窗口孔141,以使该间隔黏合层140不覆盖该组件设置区115。该保护盖片150压贴于该间隔黏合层140上。
该硅穿孔结构160包含一贯穿孔161以及一孔金属层162,该贯穿孔161微偏心地对准该偏移垫114由该第四表面122连续贯穿该载体晶片120与该装置晶片110,该孔金属层162形成于该贯穿孔161内并连接该偏移垫114,该贯穿孔161非中心对准于该间隔导体凸块130。此外,该贯穿孔161可连续式贯穿该熔合结合层190,该贯穿孔161的深度可介于10~75微米(μm)。更具体地,该贯穿孔161可连续式贯穿该绝缘层116,以显露该偏移垫114。一介电内衬164可形成于该贯穿孔161的孔壁并隔离了该孔金属层162,以避免该孔金属层162漏电流至该载体晶片120的主体。
该保护层170形成于该第四表面122上并覆盖该贯穿孔161。较佳地,该保护层170可更封闭该硅穿孔结构160的一开口163而不填入该贯穿孔161,以使该硅穿孔结构160内具有与外部阻绝的空气。
该些外接端子180设置于该载体晶片120而突出于该第四表面122上。较佳地,该孔金属层162可更一体延伸为一形成于该第四表面122的重配置线路165,该些外接端子180可接合于该重配置线路165,该些外接端子180可包含多个焊球。
关于上述具硅穿孔连续型态的晶圆级晶片尺寸封装构造100的制造方法说明如后,图2A至图2J绘示在该晶圆级晶片尺寸封装构造100的制造方法中各主要步骤的组件截面示意图。
首先,请参阅图2A,提供在晶圆阶段的一装置晶片110与一载体晶片120,该装置晶片110的主体具有一第一表面111与一第二表面112,一金属互连平行垫组合113嵌埋于该装置晶片110之中,该载体晶片120的主体具有一第三表面121与一第四表面122。该金属互连平行垫组合113由多个金属垫M1、M2、M3所构成,其为相互平行并且以导体栓电性互连。其中一金属垫M3可贴平于该第二表面112。
之后,请参阅图2A及图2B,结合该装置晶片110与该载体晶片120,使得该第二表面112上的一第一熔合材料191熔合结合于该第三表面121上的一第二熔合材料192。该熔合结合步骤可包含一加热制程,使得该第一熔合材料191与该第二熔合材料192熔融后冷却结合在一起,进而形成一熔合结合层190。该熔合结合层190可为一键合氧化层。
之后,请参阅图2C,一第一晶圆薄化步骤实施在上述结合该装置晶片110与该载体晶片120的步骤之后与在设置一偏移垫114(如图2D所示)于该第一表面111的步骤之前,以降低该装置晶片110的厚度。

在本实施例中,该保护层170形成于该第四表面122上并覆盖该贯穿孔161。该保护层170可更封闭该硅穿孔结构160的一开口163而不填入该贯穿孔161,以使该硅穿孔结构160内具有与外部阻绝的空气。
