Abstract:
1. A method of packaging a semiconductor device, the method comprising: providing a first integrated circuit die, the first integrated circuit die being coupled to a first surface of a substrate including a plurality of through-substrate vias (TSVs) disposed therein; coupling a conductive ball to each of the plurality of TSVs on a second surface of the substrate, the second surface being opposite the first surface of the substrate; coupling a second integrated circuit die to the second surface of the substrate; forming a molding compound over the conductive balls, the second integrated circuit die, and the second surface of the substrate; removing the molding compound from over a top surface of the conductive balls; recessing the top surface of the conductive balls; and forming a redistribution layer (RDL) over the top surface of the conductive balls and the molding compound.
