Abstract:
1. A method of manufacturing an integrated circuit packaging system comprising: fabricating an interposer array having an access opening; fabricating a base package substrate sheet having system interconnects on lower surface contacts; attaching a first integrated circuit die over the base package substrate sheet; attaching a second integrated circuit die over the first integrated circuit die; mounting the interposer array over the first integrated circuit die; and the second integrated circuit die; molding an encapsulant, for covering the first integrated circuit die, the second integrated circuit die, and the base package substrate sheet, through the access opening including a top portion of the interposer array exposed from the encapsulant; and singulating a base package from the base package substrate sheet and the interposer array by singulating the interposer array, substantially through the center of the access opening, and the base package substrate sheet, between the system interconnects, with a singulation device including exposing an interposer having recessed edges and corners exposed on a singulation edge.
