技术领域
本公开涉及半导体封装技术。
背景技术
半导体器件普遍存在于现代电子产品中。半导体器件中的电子部件数量和密度各不相同。离散半导体器件通常包含一种类型的电子部件,例如发光二极管(LED)、小信号晶体管、电阻器、电容器、电感器和功率金属氧化物半导体场效应晶体管(MOSFET)。集成半导体器件通常包含数百至数百万个电子部件。集成半导体器件的示例包括微控制器、微处理器、电荷耦合器件(CCD)、太阳能电池和数字微镜器件(DMD)。
半导体器件执行多种功能,例如信号处理,高速计算,发送和接收电磁信号,控制电子器件,将太阳光转换成电以及为电视显示器创建可视投影。半导体器件应用在娱乐、通信、功率转换、网络、计算机和消费产品领域中。半导体器件还应用于军事应用、航空、汽车、工业控制器和办公设备。
半导体器件利用半导体材料的电气特性。半导体材料的原子结构允许通过施加电场或基极电流或通过掺杂过程来控制其导电性。掺杂将杂质引入半导体材料中,以操控和控制半导体器件的导电性。
半导体器件包含有源电气结构和无源电气结构。有源结构(包括双极型和场效应晶体管)控制电流的流动。通过改变掺杂水平以及施加电场或基极电流,晶体管可以促进或限制电流的流动。无源结构(包括电阻器、电容器和电感器)在执行各种电气功能所需的电压和电流之间建立关系。无源结构和有源结构被电连接以形成电路,所述电路使半导体器件能够执行高速计算和其他有用功能。
半导体器件通常使用两个复杂的制造工艺来制造,即,前端制造和后端制造,每个制造工艺均可能涉及数百个步骤。前端制造涉及在半导体晶圆的表面上形成多个管芯。每个半导体管芯通常是相同的,并且包含通过电连接有源部件和无源部件而形成的电路。后端制造涉及从完成的晶圆中分离出单个半导体管芯,并封装管芯以提供结构支撑和环境隔离。
在整个说明书中,术语“管芯”、“半导体芯片”和“半导体管芯”可互换使用。本文中使用的术语“晶圆”包括根据本发明的具有在其上沉积层例如以形成电路结构的暴露表面的任何结构。
图1A至1E示出了用于制造具有再分布层(RDL)的晶圆级封装的典型方法的示意性截面图。
如图1A所示,准备晶圆100。晶圆100可以包括根据已知工艺形成的多个半导体器件结构(未示出)。然后根据已知工艺在晶圆100上形成RDL层。在图1A至1E中,RDL象征性地示出为一组层102、104和106。RDL通常是通过在晶圆的表面上添加金属和电介质层以将I/O布局重新布线为更宽松的间距占位区(pitch footprint)来限定的。这样的再分布通常包括薄膜聚合物如BCB、PI或其他有机聚合物和金属化物(如Al或Cu),以将外围焊盘重新布线为面积阵列配置。层102和106表示电介质层,层104表示金属特征。层102、104和106共同表示电介质和金属层,其形成为允许从晶圆100到图1E所示的焊接凸块或焊接球108的电气通信。在RDL上形成焊接球108以用于进一步连接。同样如图1E所示,可以沿着晶圆的切口区域进行切割或锯切工艺,以将单个晶圆级管芯彼此分开。
在晶圆级封装中,晶圆和管芯由于热膨胀系数(CTE)不匹配而容易翘曲。众所周知,晶圆翘曲仍然是令人担忧的问题。由于无法保持管芯和晶圆的耦合,翘曲会阻止管芯-晶圆堆叠体的成功组装。翘曲问题尤其是在大尺寸晶圆中是严重的,并且已经对要求精细间距RDL工艺的晶圆级半导体封装工艺产生了障碍。
本公开提供新颖的改进的封装方法,从而减少翘曲或其他缺陷。

图4是示出根据本公开的用于制造晶圆级封装的示例性方法的工艺流程图。
具体实施方式
本公开涉及晶圆级封装工艺。例如,在半导体晶圆封装工艺中,晶圆可以是其上具有数千个芯片的半导体晶圆或器件晶圆。薄晶圆,尤其是超薄晶圆(厚度小于60微米或甚至小于30微米)非常不稳定,比传统的厚晶圆更容易受到应力的影响。在加工期间,薄晶圆可能容易断裂和翘曲。因此,将其临时结合到刚性支撑载体基板上可以减少晶圆损坏的风险。载体基板可以是由玻璃、蓝宝石、金属或其他刚性材料制成的正方形或矩形面板,以增加芯片的体积。在一种晶圆封装方法中,将晶圆临时放置在临时的涂覆有粘合剂的载体基板上,将其密封在诸如环氧树脂模制化合物之类的密封剂材料中。然后将密封的晶圆用期望的半导体封装操作进行处理,所述操作包括RDL形成和切割成单个芯片。
在本发明的以下详细描述中,对附图进行了参照,这些附图构成本发明的一部分,并且在附图中通过说明的方式示出了可以实践本发明的特定实施例。对这些实施例进行了足够详细的描述,以使本领域技术人员能够实施本发明。在不脱离本发明的范围的情况下,可以利用其他实施例并且可以进行结构改变。
因此,以下详细描述不应被理解为限制性的,并且本发明的范围仅由所附权利要求以及这些权利要求所赋予的等同物的全部范围来限定。
现在将参照附图描述本发明的一个或多个实施方式,其中,贯穿全文,相似的附图标记用于指代相似的元件,并且其中所示的结构不是一定按比例绘制。
图2A至2E示出了表示根据本公开的用于制造晶圆级封装的示例性方法的示意性截面图。
如图2A所示,准备载体基板202。载体基板202可以包括可离型的基板材料。将粘合剂层206设置在载体基板202的顶表面上。在一个实施例中,载体基板202可以是玻璃基板,但是替代地,也可以是CTE与待加工的晶圆200的CTE匹配的任何其他材料。例如,载体基板202也可以是陶瓷、蓝宝石或石英。粘合层206可以是粘合带,或者替代地,可以是经由旋涂工艺等施加到载体基板202上的胶水或环氧树脂。
随后,晶圆200和框架构件204可以经由粘合剂层206安装在载体基板202的支撑表面上。在图3中还示出了示例性框架构件204的平面图。在一些实施例中,不需要任何框架构件204。换言之,晶圆200将经由粘合剂层206安装在载体基板202的支撑表面上,而没有任何相邻的框架构件204。载体基板可以由玻璃或其他合适的材料形成,这些材料的CTE至少与晶圆200的CTE基本匹配。例如,载体基板202也可以是陶瓷、蓝宝石或石英。晶圆200可以包括在其上形成的半导体电路,所述半导体电路适于被切开或切割成多个管芯。框架构件204可以包括多个通孔,将所述多个通孔的尺寸和形状设置为允许相应的晶圆200定位在其中,如图2A至2E和图3所示。还可以将框架构件204称为增强件材料。在一些实施例中,框架构件204可以由玻璃、陶瓷、蓝宝石、石英或CTE至少与晶圆200和/或载体基板202的CTE基本匹配的其他合适的材料形成。
组装的顺序可以变化;换言之,可以在放置晶圆200之前、期间或之后放置框架构件204。此外,虽然示出了四个晶圆200和通孔,但是替代实施例可以包括任何数量的晶圆200和通孔。此外,虽然图中所示的框架构件204为正方形并且图中所示的晶圆200为圆形,但是框架构件204的替代实施例可以具有任何期望的形状。例如,框架构件204可以是圆形或矩形,并且同样地,晶圆200也可以是正方形或矩形。可以通过使用任何常规的表面安装技术将晶圆200和框架构件204安装在载体基板202上,所述表面安装技术包括粘合剂、胶水和/或临时胶带,但不限于此。
如图2B所示,在将晶圆200和框架构件204安装在载体基板202上之后,施加诸如模制化合物208之类的密封剂。模制化合物208覆盖粘附的晶圆200和框架构件204。在没有框架构件204的实施例中,模制化合物208将仅覆盖粘附的晶圆200。模制化合物208还可以填充晶圆200与框架构件204之间可能存在的任何间隙。然后可以使模制化合物208经历固化过程。在不存在框架构件204的一些实施例中,模制化合物208将仅填充晶圆200之间的间隙。
根据图示实施例,例如,可以在转移模压机中使用热固性模制化合物来形成模制化合物208。可以使用其他分配模制化合物的方式。可以使用在高温下为液体或在环境温度下为液体的环氧树脂、树脂和化合物。模制化合物208可以是电绝缘体并且可以是热导体。可以添加不同的填充剂以增强模制化合物208的导热性、刚性或粘附性。
接下来,转向图2C至2E,注意图示结构已经被翻转,使得如图2A至2B所示的顶侧是如图2C至2E所示的底侧。如图2C所示,在形成模制化合物208之后,移除或剥离载体基板202和粘合剂层206以使晶圆200和框架构件204暴露。
如图2D所示,随后,可以使用已知的RDL形成技术来制造RDL 210。此外,为了提供RDL 210与其他电路之间的电连接,形成了多个凸块212,如微凸块或铜柱。可选地,可以进行热处理以使凸块212进行回流焊(reflow)。
如图2E所示,可以沿着切口区域进行切割或锯切过程,以将各个晶圆200及其各自的晶圆级封装彼此分开。应当理解,附图中描绘的截面结构仅用于说明目的。
图4是示出根据本公开的用于制造晶圆级封装的示例性方法的工艺流程图400。在该实施例中,制造半导体器件的方法开始于步骤410,即,提供多个半导体基板,每个半导体基板具有各自的有源表面和至少一个各自的集成电路区域。在一个实施例中,下一步骤420涉及将所述多个半导体基板粘附到载体基板的支撑表面上,随后是步骤430,即,将框架构件粘附到载体基板的支撑表面上。在替代实施例中,可以以相反的顺序进行步骤420和430,例如,步骤430之后是步骤420。下一步骤440涉及将框架构件和所述多个半导体基板密封在密封剂中,从而得到多晶圆密封层,随后是加工步骤450,即,从多晶圆密封层中移除载体基板。所述工艺的下一步骤460包括在多晶圆密封层的半导体基板上形成再分布层(RDL),从而得到多晶圆面板。在一个实施例中,可以进一步对多晶圆面板进行切割步骤470,由此可以使多层面板单片化以获得单独的半导体器件。

在一些实施例中,在以上讨论的方法中,所述载体基板的热膨胀系数(CTE)可以与所述第一半导体基板和第二半导体基板的CTE基本匹配。同样地,所述框架构件的热膨胀系数(CTE)与所述第一半导体基板和第二半导体基板的CTE和/或所述载体基板的CTE基本匹配。
在一个实施例中,所述框架构件的至少一部分沿着所述载体的所述支撑表面在所述第一半导体基板和第二半导体基板之间延伸。在另一个实施例中,如上所讨论的方法可以进一步包括将所述多晶圆面板切割以获得单独的半导体器件。在一些实施例中,所述第一半导体基板和第二半导体基板中的每一个均包含硅,并且所述框架构件的热膨胀系数(CTE)与硅的CTE基本匹配。

在一些实施例中,在以上讨论的方法中,所述载体基板的热膨胀系数(CTE)可以与所述第一半导体基板和第二半导体基板的CTE基本匹配。在其他实施例中,所述框架构件的热膨胀系数(CTE)可以与所述第一半导体基板和第二半导体基板的CTE和/或所述载体基板的CTE基本匹配。
在一个实施例中,所述第一半导体基板和第二半导体基板中的每一个均包含硅。在另一个实施例中,所述框架构件的热膨胀系数(CTE)与硅的CTE基本匹配。
在一个实施例中,以上讨论的方法进一步包括将多晶圆面板切割以获得单独的半导体器件。
在一个实施例中,制造半导体器件的方法不需要包括步骤430。换言之,所述方法开始于提供多个半导体基板的步骤410,其中每个半导体基板具有各自的有源表面和至少一个各自的集成电路区域,随后进行下一步骤420,即,将所述多个半导体基板粘附到载体基板的支撑表面上。再下一步骤440包括将所述多个半导体基板密封在密封剂中,从而得到多晶圆密封层。在该实施例中,没有框架构件204。所述方法继续进行从所述多晶圆密封层中移除所述载体基板的步骤450,随后进行下一步骤460,即,在所述多晶圆密封层的所述半导体基板上形成再分布层(RDL),从而得到多晶圆面板。在一个实施例中,可以进一步对所述多晶圆面板进行切割步骤470,从而可以使多层面板单片化以获得单独的半导体器件。
