Patent ID: 8541872

Claim:
A method of manufacture of an integrated circuit package system comprising: forming a non-inverted internal stacking module including: fabricating an internal stacking module (ISM) substrate having an ISM component side and an ISM coupling side, coupling an internal stacking module integrated circuit to the ISM component side, coupling stacking structures, adjacent to the internal stacking module integrated circuit, on the ISM component side, and molding a stacking module body having a top surface that is coplanar with and exposes the stacking structures; forming a base package substrate under the non-inverted internal stacking module; coupling middle structures between the base package substrate and the ISM coupling side; and forming a base package body on the base package substrate, the middle structures, the ISM coupling side, the stacking module body, and the non-inverted internal stacking module, the base package body having a top surface coplanar with the top surface of the stacking module body and a top stacking surface of the stacking structures.
