Patent ID: 8729687

Claim:
A method of manufacturing a stackable integrated circuit package system comprising: forming a first external interconnect; positioning a first integrated circuit die below the first external interconnect; connecting the first integrated circuit die with the first external interconnect; and forming a recessed encapsulation, the recessed encapsulation on the first integrated circuit die and the first external interconnect, the recessed encapsulation having: a first recess at an outer extent of bottom and lower side surfaces of the recessed encapsulation, wherein only a bottom surface of the first external interconnect is exposed by the first recess and wherein a bottom side of the first integrated circuit die is entirely exposed at a bottom surface of the recessed encapsulation, the first recess along outermost bottom and lower side edges of the integrated circuit package system, and a second recess at an outer extent of top and upper side surfaces of the recessed encapsulation, the first external interconnect not exposed by the second recess, the second recess along outermost top and upper side edges of the integrated circuit package system.
