Abstract:
1. A method of manufacture of an integrated circuit packaging system comprising: providing an interposer having interposer fingers, interposer pads, interposer peripheral sides, an interposer bottom side, and an interposer top side, wherein the interposer fingers and the interposer pads are formed as single integral structures, the interposer fingers are adjacent and along only one of the interposer peripheral sides, and the interposer pads are adjacent the interposer peripheral sides; attaching a base integrated circuit to the interposer bottom side; mounting a stack integrated circuit over the base integrated circuit, the stack integrated circuit overhangs the base integrated circuit; attaching an internal electrical connector directly to the stack integrated circuit and the base integrated circuit; attaching a lead to the interposer bottom side, the lead adjacent the base integrated circuit and entirely below the interposer; and forming an encapsulation partially covering the lead and exposing the interposer top side; and wherein: attaching the lead includes attaching the lead having a lead outer portion below the encapsulation.
