Claim:
1. A method comprising: receiving a bottom package comprising a substrate material having a top layer including a first set of pads and a second set of pads, wherein the first set of pads is configured to be electrically coupled to a third set of pads of an integrated circuit die; applying a layer of non-conductive material to the top layer of the bottom package, wherein the layer of non-conductive material directly covers both the first set of pads and the second set of pads; and removing a portion of the layer of non-conductive material to form a cavity in the layer of non-conductive material that exposes the first set of pads before forming vias through the layer of non-conductive material outside of the cavity, wherein the cavity is configured to contain the integrated circuit die oriented such that the third set of pads of the integrated circuit die face the first set of pads.
