Stacked semiconductor module, method of fabricating the same, and electronic system using the same

Abstract

A stacked semiconductor module, a method of fabricating the same, and an electronic system using the module are provided. A first semiconductor module having a plurality of semiconductor devices mounted on a rigid printed circuit board (PCB) and a second semiconductor module having a plurality of other semiconductor devices mounted on a flexible PCB are provided. On the rigid PCB a number L of first tabs may be disposed on a first surface, and a number K of second tabs may be disposed on a second surface of the rigid PCB. The flexible PCB may have a number M of third tabs on a third surface, and a number N of fourth tabs on a fourth surface of the flexible PCB. The second tabs may be combined with the third tabs using a conductive adhesive. The third tabs may be electrically connected to corresponding ones of the second tabs.
