摘要： Disclosed is a method of planarizing an array of plastically-deformable electrical contacts on an integrated circuit. An integrated circuit is placed on a plate with an array of plastically-deformable electrical contacts substantially parallel to and facing the plate, thereby creating an assembly. The integrated circuit is placed above the plate such that the weight of the integrated circuit bears down on the array of plastically-deformable electrical contacts. The assembly is then heated sufficiently to cause individual ones of the plastically-deformable electrical contacts to locally soften but not to cause said individual ones of the electrical contacts to liquefy throughout their volumes. The weight of the integrated circuit applies a force to the softened plastically-deformable electrical contacts, thereby resulting in their planarization.

摘要： A package comprises a top die and a bottom die. The top die has top and bottom surfaces while the bottom die has top and bottom surfaces. The bottom die is mounted on a substrate, which has a top surface, such that the bottom surface of the bottom die faces the top surface of the substrate. The bottom surface of the top die is separated from the top surface of the bottom die by an interposer, which creates a space between the exterior regions of the top surface of the bottom die and the bottom surface of the top die. Each of a plurality of wires, which are electrically connected to the bottom die, runs through this space (i.e. runs between the top surface of the bottom die and the bottom surface of the top die), thereby permitting (if desired) the top die to be at least as large as the bottom die.
