Abstract: Embodiments are generally directed to a swaging process for complex integrated heat spreaders. An embodiment of an integrated heat spreader includes components, each of the components including one or more swage points; and a multiple swage joints, each swage joint including a swage pin joining two or more components, wherein components are joined into a single integrated heat spreader unit by the swage joints.

Abstract: Embodiments are generally directed to cooling of electronics using folded foil microchannels. An embodiment of an apparatus includes a semiconductor die; a substrate, the semiconductor die being coupled with the substrate; and a cooling apparatus for the semiconductor die, wherein the cooling apparatus includes a folded foil preform, the folded foil forming a plurality of microchannels, and a fluid coolant system to direct a fluid coolant through the microchannels of the folded foil.

Abstract: Semiconductor package interposers having high-density and high-aspect ratio encapsulated interconnects, and semiconductor package assemblies incorporating such interposers, are described. In an example, a semiconductor package interposer includes several conductive interconnects encapsulated in a polymer substrate and having height dimensions greater than a cross-sectional dimension. The semiconductor package interposer may support a first semiconductor package above a second semiconductor package and may electrically connect die pins of the first semiconductor package to die pins of the second semiconductor package.
