Patent ID: 7863109

Claim:
A method of manufacture of an integrated circuit packaging system comprising: providing a module die; connecting the module die to a first contact pad and a second contact pad of an inner stacking module encapsulation; encapsulating the module die with the inner stacking module encapsulation to form an inner stacking module, the inner stacking module encapsulation having an inner stacking module protrusion having a planar protrusion surface and the inner stacking module protrusion surrounds an inner stacking module cavity, the inner stacking module protrusion separates the first contact pad and the second contact pad with the first contact pad being along a perimeter of the inner stacking module encapsulation and with the second contact pad being positioned in the inner stacking module cavity; and encapsulating at least part of the inner stacking module encapsulation with an encapsulation having a flat top coplanar with the planar protrusion surface or fully encapsulating the inner stacking module encapsulation.
