Classification: CPC H | IPC H

Claim 8:
9. An electronic device comprising:
a redistribution structure comprising a redistribution structure top side and a redistribution structure bottom side;
a first semiconductor die comprising a first die top side, a first die bottom side, and a first die lateral side between the first die top side and the first die bottom side;
first conductive pillars coupling the first die bottom side to the redistribution structure top side;
a second semiconductor die comprising a second die top side, a second die bottom side, and a second die lateral side between the second die top side and the second die bottom side;
second conductive pillars coupling the second die bottom side to the redistribution structure top side;
an underfill material that underfills the first semiconductor die and the second semiconductor die, wherein the underfill material contacts the first die lateral side and the second die lateral side;
a routing patch comprising a patch top side and a patch bottom side, wherein:
the patch top side is coupled to the redistribution structure bottom side;
the routing patch comprises patch traces that couple the first semiconductor die to the second semiconductor die;
the patch traces have a trace line density that is denser than a trace line density of the redistribution structure; and

conductive interconnection structures below the redistribution structure and laterally displaced from the routing patch.
