发明名称 Apparatus and method for stacking integrated circuit devices
摘要 An apparatus and method for stacking integrated circuit devices which combine flip-chip technology and soldering methods with laminated stack frames to provide a vertical stack array with minimal parasitic inductance. Each laminated stack frame has a central cavity and includes a plurality of vias extending through them. The vias have top surfaces and bottom surfaces, wherein the bottom surfaces each contain a solder bump. Each laminated stack frame also includes a plurality of solder bump pads extending into the cavity to contact corresponding solder bumps on a flip-chip integrated circuit chip, and a plurality of traces coupling each solder bump pad to a via. The bottom surfaces of the vias of a bottom laminated stack frame couple to contacts on a printed circuit board.
