Patent ID: 8067829

Claim:
A multi-chip module system, comprising: a substrate having a surface; a first die having a first surface coupled to the surface of the substrate and having a second surface; an interposer unit, including first and second partitions, each partition having an upper and lower surface, wherein the lower surface of the first partition is coupled to the second surface of the first die, wherein a first direction is perpendicular to the first and second partitions, and a second direction is parallel to the first and second partitions, and a plurality of solder bumps physically coupling the upper surface of the first partition to the lower surface of the second partition and configured to fracture when a force is applied to the interposer, wherein the force required to fracture the interposer when applied in the second direction is approximately one-tenth the force required to fracture the interposer when the force is applied in the first direction; and a second die having a first surface coupled to the upper surface of the second partition.
