Description

半导体封装及其制造方法
技术领域
本公开涉及一种半导体封装及其制造方法,特别关于一种具有在两个横向相邻元件之间实现横向信号路径的凸块结构的半导体封装及其制造方法。
背景技术
半导体元件对于许多现代应用而言是重要的。随着电子技术的进展,半导体元件的尺寸越来越小,而功能越来越大且整合的电路量越来越多。由于半导体元件的尺度微小化,芯片上覆置芯片(chip-on-chip)技术目前广泛用于制造半导体元件。在此半导体封装的生产中,实施了许多制造步骤。
因此,微型化规模的半导体元件的制造变得越来越复杂。制造半导体元件的复杂度增加可能造成缺陷,例如电互连不良、产生裂纹、或是组件脱层。据此,半导体元件的结构与制造的修饰有许多挑战。
上文的“现有技术”说明仅是提供背景技术,并未承认上文的“现有技术”说明公开本公开的标的,不构成本公开的现有技术,且上文的“现有技术”的任何说明均不应作为本公开的任一部分。

在一些实施例中,半导体元件110A通过凸块结构210A的横向延伸(跨过第一侧113A)可接触横向相邻元件的对应导体;如此,在未使用对应于图1所示的重布线层11的重布线结构下,即可实现半导体元件110A与横向相邻元件之间的横向信号路径。
图3为剖面示意图,例示本公开实施例的半导体封装100B,以及图4为图3的半导体封装的分解示意图,说明。图3所示的半导体封装100B与图2所示的半导体封装100A实质相同,差别在于图3的半导体元件110B的传导接垫105B以及位于传导接垫105B上的凸块结构210B;其中在图4中,为了清楚说明,凸块结构210B自传导接垫105B上分解。
在图2中,在右上边缘处的传导接垫105A具有实质平面的轮廓(planar profile);相对地,在图3中,在右上边缘处的传导接垫105B(作为边缘凸垫)具有阶梯垫轮廓,并且在右上处的凸块结构120B的底部具有阶梯凸块轮廓,面对传导接垫105B(作为边缘凸垫)的阶梯垫轮廓。在一些实施例中,半导体元件100B包括一缺角部117B暴露边缘凸垫,并且凸块结构210B填充该缺角部117B。

在一些实施例中,第一上表面111B与第二上表面121B为沿着垂直方向(附图中的Z方向)的不同阶层(level),并且凸块结构210B自第一上表面111B垂直延伸至半导体元件100B的第二上表面121B。在一些实施例中,凸块结构210B位于第二上表面121B与第一上表面111B上;此外,凸块结构210B沿着侧向(附图中的X方向)横向延伸跨过半导体元件100B的第二侧123B与第一侧113B。
在一些实施例中,在右上边缘处的凸块结构210B的横向延伸(跨过半导体元件110B的第一侧113B)可接触横向相邻元件的对应导体;如此,在未使用对应于图1所示的重布线层11的重布线结构下,即可实现半导体元件110B与横向相邻元件之间的横向信号路径。
图5为剖面示意图,例示本公开实施例的半导体封装100C。图5所示的半导体封装100C与图3所示的半导体封装100B实质相同,差别在于半导体元件110C的传导接垫105C的差异。在图3中,在右上边缘处的传导接垫105B(作为边缘凸垫)为一体成形物件;相对地,在图5中,在右上边缘处的传导接垫105C(作为边缘凸垫)是由许多部分1051A、1051B与1051C构成。在一些实施例中,所述部分1051A、1051B与1051C可由不同导体制成。
图6为剖面示意图,例示本公开实施例的半导体封装100D。在一些实施例中,半导体封装100D包括:第一半导体元件130A;第二半导体元件130B,与第一半导体元件130A横向相邻;模制件140,囊封第一半导体元件130A与第二半导体元件130B;以及在第一半导体元件130A与第二半导体元件130B之间实现横向信号路径的凸块结构210D。在一些实施例中,第一半导体元件130A与第二半导体元件130B可为图2所示的半导体元件110A。
在一些实施例中,凸块结构210D自第一半导体元件130A的上表面横向延伸至第二半导体元件130B的上表面。在一些实施例中,模制件140的中间部分141位于第一半导体元件130A与第二半导体元件130B之间,并且凸块结构210D横向延伸跨过模制件140的中间部分141。
在一些实施例中,第一半导体元件130A与第二半导体元件130B为单一晶圆的两个相邻芯片。在一些实施例中,第一半导体元件130A与第二半导体元件130B为不同晶圆的两个芯片。在一些实施例中,半导体封装100A另包括垂直凸块结构220A(实现第一半导体元件130A的垂直信号路径)以及垂直凸块结构220B(实现第二半导体元件130B的垂直信号路径)。
在一些实施例中,在未使用对应于图1所示的重布线层11的重布线结构下,凸块结构210D实现第一半导体元件130A与第二半导体元件130B之间的横向信号路径。因此,图6的半导体封装100D的高度小于图1的半导体封装10的高度。换言之,图6的半导体封装100D可符合半导体封装的尺度微小化需求(小尺寸架构)。省略对应于图1所示的重布线层11的重布线结构为图6的半导体封装100D制造成本降低的主要因素。
图7为剖面示意图,例示本公开实施例的半导体封装100E。在一些实施例中,半导体封装100E包括:第一半导体元件150A;第二半导体元件150B,与第一半导体元件150A横向相邻;囊封第一半导体元件150A与第二半导体元件150B的模制件160;以及在第一半导体元件150A与第二半导体元件150B之间实现横向信号路径的凸块结构210E。在一些实施例中,第一半导体元件150A可为图3所示的半导体元件110B,以及第二半导体元件150B可为图5所示的半导体元件110C。

在一些实施例中,在未使用对应于图1所示的重布线层11的重布线结构下,凸块结构210E在第一半导体元件150A与第二半导体元件150B之间实现横向信号路径。因此,图7的半导体封装100E的高度小于图1的半导体封装10的高度。换言之,图7的半导体封装100E可符合半导体封装的尺度微小化需求(小尺寸架构)。此外,省略对应于图1所示的重布线层11的重布线结构为图7的半导体封装100E制造成本降低的主要因素。

本公开的实施例提供一种半导体封装,具有在两个横向相邻的半导体元件之间实现横向信号路径的凸块结构,并未使用重布线结构。因此,本公开的半导体封装的高度小于具有重布线结构的半导体封装的高度。换言之,本公开的半导体封装可符合半导体封装的尺度微小化需求(小尺寸架构)。此外,未使用重布线结构为半导体封装制造成本降低的主要因素。
在本公开的一些实施例中,该半导体封装包含一第一元件以及位于该第一元件上的一凸块结构。在一些实施例中,该第一元件具有一第一上表面与一第一侧,其中该第一上表面与该第一侧形成该第一元件的一第一角部。在一些实施例中,该凸块结构位于该第一上表面上,并且横向延伸跨过该第一元件的该第一侧。
