Abstract

一种连接器组件以及用于制造连接器组件的方法。根据实施例，连接器组件包括具有第一和第二表面以及第一和第二端部的电连接器。一层电绝缘材料由在第一端部的第一表面的一部分形成或者被形成于该部分之上。可选地，一层电绝缘材料能够由第二表面形成或者被形成第二表面之上。

Description

连接器组件及制造方法
技术领域
本发明一般地涉及电子领域，并且更特别地涉及连接器组件。
背景技术
在过去，半导体工业制造包含在保护结构(例如，塑封料)之内的单个半导体管芯的半导体零件。各种类型的半导体零件被安装于含有允许半导体零件相互通信的互连结构的印制电路板。随着在电子器件中对更多功能的需求增大，希望将更多的半导体零件包含于印制电路板上。因而，半导体制造商一直努力制造具有更小的外形及安装占用面积的半导体零件。
在某些实施例中，半导体管芯以粘合材料插入层相互垂直堆叠，该粘合材料插入层附接于半导体管芯以便将管芯键合到一起以形成多芯片或多管芯结构。多芯片结构被附接于玻璃树脂型的印制电路板基板或其他相似的基板。然后使半导体管芯丝线键合于基板以在基板和半导体管芯之间形成电互连。在2003年11月18日颁予ThomasB.Glenn等人的美国专利No.6,650,019中公开了此类封装结构的一个实例。在2006年4月18日颁予ToddP.Oman的美国专利No.7,030,317中公开了具有层叠的集成电路管芯的电子组件的一个实例。
层叠半导体管芯的缺点包括形成半导体管芯之间的电互连以及去除来自堆叠结构的热量。
因此，拥有适合于在半导体管芯及半导体零件之间传输电信号并且提供半导体管芯的足够的热耗散的连接器组件将是有利的。有利的是该电子组件及方法的实现是有成本和时间效益的。

电连接器472A与电绝缘层552耦连以形成连接器组件550。更特别地，表面474在端部区域482中。参考标记“A”已经被附加到参考标记472上以区分形成连接器组件550的两个电连接器。本发明并不限制相互叠加以形成连接器组件的电连接器472的数目。
应当意识到，至此已经提供了连接器组件以及用于制造连接器组件的方法。根据本发明的实施例，连接器组件包括具有相对的端部和相反的表面的电连接器。电绝缘材料可以形成于电连接器的一个或两个端部中的一个或两个表面的某些部分上。连接器组件可以用来形成具有层叠的半导体管芯的半导体零件。连接器组件使半导体管芯能够堆叠由此减少在印制电路板上的占用面积并且允许从半导体零件中有效地去除热量。
虽然在此已经公开了具体的实施例，但是这并不意欲本发明仅限于所公开的实施例。本领域技术人员应当意识到修改和改变能够在不脱离本发明的精神的情况下进行。希望本发明包括在所附权利要求书的范围之内的所有此类修改和改变。
