Abstract

Techniques for fabricating multiple device components. Specifically, techniques for fabricating a stacked package comprising at least one I/C module and a multi-chip package. The multi-chip package includes a plurality of integrated circuit dices coupled to a carrier. The dice are encapsulated such that conductive elements are exposed through the encapsulant. The conductive elements are electrically coupled to the chips. The I/C module comprises an interposer having a plurality of integrated circuit dice disposed thereon. The dice of the I/C module are electrically coupled to the interposer via bondwires. The interposer is configured such that vias are aligned with the conductive elements on the multi-chip package. The multi-chip package and I/C module may be fabricated separately and subsequently coupled together to form a stacked package.

Claims (25)
