PACKAGE-ON-PACKAGE SYSTEM WITH THROUGH VIAS AND METHOD OF MANUFACTURE THEREOF

摘要

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.
