    Abstract: Methods/structures of joining package structures are described. Those methods/structures may include forming a metal formate on a surface of a first solder interconnect structure disposed on a first package substrate at a first temperature, and attaching a second solder interconnect structure disposed on a second package substrate to the first solder interconnect structure at a second temperature. The second temperature decomposes at least a portion of the metal formate and generates a hydrogen gas. The generated hydrogen gas removes an oxide from the second solder interconnect structure during joint formation at the second temperature.

    Abstract: Embodiments of the present disclosure are directed towards techniques and configurations of interconnect structures having a polymer core in integrated circuit (IC) package assemblies. In one embodiment, an apparatus includes a first die having a plurality of transistor devices disposed on an active side of the first die and a plurality of interconnect structures electrically coupled with the first die, wherein individual interconnect structures of the plurality of interconnect structures have a polymer core, and an electrically conductive material disposed on the polymer core, the electrically conductive material being configured to route electrical signals between the transistor devices of the first die and a second die. Other embodiments may be described and/or claimed.
