Patent ID: 10403599

Abstract:
Embedded organic interposers for high bandwidth are provided. Example embedded organic interposers provide thick conductors with more dielectric space, and more routing layers of such conductors than conventional interposers, in order to provide high bandwidth transmission capacity over longer spans. The embedded organic interposers provide high bandwidth transmission paths between components such as HBM, HBM2, and HBM3 memory stacks, and other components. To provide the thick conductors and more routing layers for greater transmission capacity, extra space is achieved by embedding the organic interposers in the core of the package. Example embedded organic interposers lower a resistive-capacitive (RC) load of the routing layers to provide improved signal transmission of 1-2 GHz up to 20-60 GHz bandwidth for each 15 mm length, for example. The embedded organic interposers are not limited to use with memory modules.
