Abstract:
1. A method of manufacture of an integrated circuit packaging system comprising: providing an internal structure substrate having an internal structure substrate cavity; mounting an internal structure die above the internal structure substrate; encapsulating the internal structure die with an internal structure encapsulation to form an internal structure package; forming an internal structure protrusion of the internal structure encapsulation below the internal structure substrate cavity; mounting the internal structure package above a first integrated circuit and the internal structure package is over an edge of the first integrated circuit and the internal structure protrusion is attached directly to an active side of the first integrated circuit creating a gap between the internal structure package and the first integrated circuit; wherein: mounting the internal structure package includes mounting the internal structure package above a substrate; and further comprising: encapsulating the internal structure package above the substrate with an encapsulation.
