Abstract: Semiconductor packages including local interconnects and methods of fabrication are described. In an embodiment, a local interconnect is fabricated with one or more cavities filled with a low-k material or air gap where a die-to-die routing path electrically connecting the first die and the second die includes the metal wire spanning across the one or more cavities. In other embodiments fanout can be utilized to create a wider bump pitch for the local interconnect, or for the local interconnect to connect core regions of the dies. Multiple local interconnects can also be utilized to scale down electrostatic discharge.
