Description
技术领域
本发明实施例涉及集成电路封装件及其形成方法。
背景技术
半导体器件用在诸如个人电脑、手机、数码相机和其它电子设备的各种电子应用中。通常通过在半导体衬底上方依次沉积绝缘或介电层、导电层和半导体材料层,并且使用光刻图案化各个材料层以在其上形成电路组件和元件来制造半导体器件。通常,在单个半导体晶圆上制造数十或数百个集成电路。通过沿着划线锯切集成电路来分割单独的管芯。然后,以多芯片模块或以封装的其他类型来将单独的管芯分别进行封装。
由于各种电子组件(例如,晶体管、二极管、电阻器、电容器等)的集成密度的不断提高,半导体行业已经历了快速的发展。在很大程度上,集成密度的这种提高源自最小部件尺寸的重复减小(例如,将半导体工艺节点减小至亚20nm节点),这允许在给定区域中集成更多的组件。由于最近对微型化、更高速度和更大带宽以及更低功耗和延迟的需求不断增长,因此亟需用于半导体管芯的更小且更具创造性的封装技术。
随着半导体技术的进一步发展,已经出现了堆叠的半导体器件(例如,三维集成电路(3DIC))作为有效替代以进一步减小半导体器件的物理尺寸。在堆叠的半导体器件中,在不同半导体晶圆上制造诸如逻辑、存储器、处理器电路等的有源电路。两个或更多的半导体晶圆可以安装或堆叠在彼此的顶部上以进一步降低半导体器件的形状因数。叠层封装(POP)器件是一种类型的3DIC,其中,封装管芯并且然后将管芯与另一封装的一个管芯或多个管芯封装在一起。封装件上芯片(COP)器件是另一类型的3DIC,其中,封装管芯并且然后将管芯与另一管芯或多个管芯封装在一起。

参考图9,在形成晶种层801之后,去除带703(参见图8)并且分割工件100以形成单独的集成电路管芯901。在一些实施例中,可以使用粘合剂905将工件100附接至框架903以准备用于后续的切割工艺的工件100。在一些实施例中,框架903可以是薄膜框架或任何合适的载体以为后续操作(诸如切割)提供机械支撑。粘合剂905可以是管芯附接膜、切割膜或任何合适的粘合剂、环氧树脂、紫外(UV)胶(当暴露于UV辐射时失去其粘合性)等,并且可以使用沉积工艺、旋涂工艺、印刷工艺、层压工艺等来形成。在一些实施例中,粘合剂905可以具有多层结构并且可以包括释放层(未示出)。在完成切割工艺之后,释放层有助于安全地从框架903去除单独的集成电路管芯901。在一些实施例中,释放层可以是UV型,其中在将释放层暴露于UV辐射之后,释放层的粘合强度大幅降低。在其他实施例中,释放层可以是热型,其中,在将释放层暴露于合适的热源之后,释放层的粘合强度大幅降低。在一些实施例中,可以例如通过锯切、激光烧蚀、它们的组合等将工件100分割为单独的集成电路管芯901。
如图9所示,每个集成电路管芯901包括单个钝化层(诸如钝化层113)、单个缓冲层(诸如缓冲层201)、两个接触焊盘(诸如接触焊盘111)、两个导电柱(诸如导电柱501)以及单个保护层(诸如保护层701)。本领域技术人员将意识到提供的钝化层、缓冲层、接触焊盘、导电柱和保护层的数量仅用于说明目的,并不限制本发明的范围。在其他实施例中,根据集成电路管芯901的设计要求,每个集成电路管芯901可以包括适当数量的钝化层、缓冲层、接触焊盘、导电柱和保护层。
