Methods/structures of joining package structures are described. Those methods/structures may include a die disposed on a surface of a substrate, wherein the die comprises a plurality of high density features. An interconnect bridge is embedded in the substrate, wherein the interconnect bridge may comprise a first region disposed on a surface of the interconnect bridge comprising a first plurality of features, wherein the first plurality of features comprises a first pitch. A second region disposed on the surface of the interconnect bridge comprises a second plurality of features comprising a second pitch, wherein the second pitch is greater than the first pitch.
