Abstract: A method of manufacture of an integrated circuit packaging system includes providing a substrate; connecting an integrated circuit die; forming a molding having a temperature-dependent characteristic directly on the top surface of the substrate; and forming a coupling encapsulation having a coupled characteristic different from the temperature-dependent characteristic directly on the molding forms an encapsulation boundary between the coupling encapsulation and the molding.

Abstract: A method of manufacture of a package-on-package system includes: providing a package substrate; attaching a semiconductor die to the package substrate; forming an encapsulant around the semiconductor die to have a bottom exposed surface coplanar with a bottom surface of the package substrate and to have a top exposed surface with through openings extending therefrom through the bottom exposed surface; and creating through vias by applying solder into the through openings, the through vias coplanar with the bottom exposed surface of the encapsulant and coplanar with the top exposed surface of the encapsulant.

Abstract: A method of manufacture of an integrated circuit packaging system includes: forming a base package having a base interposer; forming an intermediate package having an intermediate interposer and an intermediate package embedded link trace, the intermediate package embedded link trace being encapsulated in an intermediate package mold compound; forming a cap package having a cap interposer; and connecting the intermediate package to the cap package and the base package using the intermediate package embedded link trace.
