具体实施方式
在详细描述本发明的任何实施例之前,需要理解的是,本发明不局限于应用到在下面的说明中陈述的或者在下面的附图中示出的部件的具体构造和布置。本发明能够实现其他实施例并且能够以各种方式实践或执行。
图1a、图1b、图1c、图2和图3示出具有开口腔构造的半导体器件100的封装设计,所述封装设计产生用于一个或多个半导体芯片102和/或MEMS裸晶105和相关的电气互连110(例如,通过引线接合或倒装芯片)的穴。组件的顶部基底115用作用于半导体芯片102和MEMS裸晶105的安装面以及用于电气信号的路由表面。在一个实施例中,顶部基底115是印刷电路板(PCB)。间隔件环120被接合到封装100的顶部基底115以形成提高半导体裸晶100和如果可适用在最终的PCB组件的表面上方的相关引线接合的壁,对在裸晶的顶面上的引线接合和/或电路提供间隙。除了形成封装壁以外,间隔件120提供用于向封装底部路由电气信号的媒介(也就是电气互连110)和在裸晶与最终的装配车辆(也就是用户PCB)之间的应变消除。在一个实施例中,间隔件120由PCB材料制成。间隔件环120的底面具有提供封装与最终组件之间电气互连的导电表面。
在一些实施例中,间隔件120围绕电气互连110形成。在顶部基底115上的电气路径(例如,轨迹)被电耦合至在间隔件120中的电气互连110。当半导体器件100被安装到制造商的电路板上时,在制造商的电路板上的电气连接经由电气互连110电耦合至半导体芯片102和MEMS裸晶105。在其他实施例中,电气互连110被在间隔件120的表面上路由。
如图3所示,半导体器件100包括间隔件/互连130。腔135通过间隔件120在器件100中形成。在半导体器件100的一些实施例中,端口140(例如,MEMS麦克风的声音端口)被穿过顶部基底115形成。
半导体器件100直接安装到制造商的电路板上并且省去对第二基底(也就是,在腔135之上)的需要。当半导体器件100被安装到制造商的电路板时,半导体器件100形成用于MEMS麦克风的必要的声学容积并且半导体器件100提供比前述可利用的封装更薄的封装。
在需要被密封的腔的应用中,密封剂(例如,倒装芯片底部填充材料、裸晶附接环氧树脂等)可以被围绕封装的周边分配或者在封装壁之下分配以在周围环境与封装的内部腔之间产生气密密封。密封的替代实施例还可以包括与焊料附接工艺兼容的围绕周边的有图案的金属环。在这种情况下,为了屏蔽的目的,环还可以被用来构成法拉第笼。这样的笼需要在封装的顶部表面上增加铜板或有图案的金属同时需要顶侧铜与在封装底部上的密封环之间的适当连接。在需要腔暴露到空气压力的情况下(诸如,压力传感器),能够部分地移除密封环,这允许在封装与PCB(封装安装在所述PCB上)之间形成空气通道。可以通过使用在封装壁内的切口或在封装的顶面内的孔产生更大的空气通道。
在图4a、图4b、图4c、图5和图6中示出的封装的替代实施例包括接合在腔135之上的盖145以形成气密密封。盖145利用薄膜(例如,聚酰亚胺胶带、聚酰亚胺)形成,所述薄膜被图案化具有开口从而露出嵌入间隔件环中的电气互连110。所述实施例改进需要限定的后部容积或密封的腔135的器件的可测试性,允许半导体器件100与MEMS麦克风一起被测试而无需安装到电路板上。仍然,所示的实施例保持前述的薄的轮廓。
因此,除其他事项以外,本发明提供一种具有超薄轮廓的用于承载一个或多个芯片和/或MEMS裸晶的半导体器件。
