Patent ID: 8742576

Claim:
A multi-chip module (MCM), comprising: a substrate having a first surface and a cavity defined by an edge in the first surface, wherein a bottom of the cavity is vertically offset from the first surface; an island chip having a second surface, wherein the island chip is mechanically coupled to the first surface; a bridge chip having a third surface that faces the second surface, wherein the bridge chip is mechanically coupled to the island chip, and wherein the bridge chip is positioned in the cavity; and a compressible structure positioned between the bottom of the cavity and a fourth surface of the bridge chip which is on an opposite side of the bridge chip from the third surface, wherein the compressible structure includes a compliant material with shape and volume compression, wherein the compressible structure is separate from the substrate, thereby allowing the compressible structure to slide laterally; and wherein the compressible structure provides a force on the bridge chip so that the second surface and the third surface are approximately coplanar without bending the bridge chip.
