Stacked integrated circuit package using a window substrate

摘要

An integrated circuit (IC) package including a substrate, a first IC, and a second IC adjacent to the first IC. The substrate includes first and second surfaces respectively having first and second bond pads, and an opening offset relative to a center of the substrate and extending from the first surface to the second surface. The first IC includes a third surface having third bond pads accessible through the opening. The second IC includes fourth and fifth surfaces respectively having fourth and fifth bond pads. The third and fifth surfaces are attached to the second surface. At least one of the third bond pads is connected to at least one of the first bond pads using one or more bond wires extending through the opening. At least one of the fourth bond pads is connected to at least one of the second bond pads using one or more bond wires.
