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.
