Patent ID: 8637394

Claim:
A method of manufacture of an integrated circuit package system comprising: providing an integrated circuit device structure having a bond pad; forming a flex bump over the integrated circuit device structure, the flex bump having both a base portion and an offset portion over the base portion, with the offset portion extending horizontally beyond a vertical line defined by a perimeter side of the bond pad; forming a first ball bond of a first internal interconnect over the offset portion; mounting a further integrated circuit device structure over the integrated circuit device structure; and wherein forming the flex bump includes: forming the base portion over a contact pad of the integrated circuit device structure with the contact pad separated with a contact distance from an edge of the further integrated circuit device structure; forming the offset portion having a side portion being at an offset distance beyond the contact distance from the edge; forming the first ball bond of the first internal interconnect over the offset portion includes: placing an internal interconnect apparatus having a nozzle width over the offset portion with the nozzle width greater than the contact distance and less than the contact distance plus the offset distance; and encapsulating the integrated circuit device structures, the flex bump, and the first internal interconnect.
