Patent ID: 7674652

Claim:
A method of making an integrated circuit package comprising the acts of: providing each of a substrate, a first die having a circuit side and a backside, and a second die having a circuit side and a backside and having connections extending through the second die; coupling the backside of the first die to the substrate via a layer of at least one of a paste, epoxy, or film; stacking the second die on the first die such that the backside of the second die is adjacent to the circuit side of the first die; coupling the connections on the backside of the second die to first conductive pads on the circuit side of the first die, wherein coupling the connections on the backside of the second die comprises the act of coupling the connections on the backside of the second die to the first conductive pads on the circuit side of the first die via solder balls; and coupling the connections on the circuit side of the second die to second conductive pads on the substrate, such that the circuit side of the first die is electrically coupled to the substrate through the connections.
