Package substrate with high density interconnect design to capture conductive features on embedded die

摘要

Embodiments of the present disclosure are directed towards techniques and configurations for interconnect structures embedded in a package assembly including a bridge. In one embodiment, a package assembly may include a package substrate, a bridge embedded in the package substrate and including a bridge substrate, and an interconnect structure including a via extending through the package substrate into a surface of the bridge substrate and configured to interface with a conductive feature disposed on or beneath the surface of the bridge substrate. The interconnect structure may be configured to route electrical signals between the conductive feature and a die mounted on the package substrate. Other embodiments may be described and/or claimed.
