Patent ID: 11901335
Assignee: AMKOR TECHNOLOGY SINGAPORE HOLDING PTE. LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An electronic device, comprising:
a substrate comprising a substrate top side and a substrate bottom side;
a first semiconductor die comprising a first die top side and a first die bottom side, wherein the first die bottom side is coupled to the substrate top side;
a second semiconductor die comprising a second die top side and a second die bottom side, wherein the second die bottom side is coupled to the substrate top side;
a routing patch comprising a patch top side, a patch bottom side, and patch contacts along the patch top side, wherein:
the patch contacts protrude above the patch top side and couple the patch top side to the substrate bottom side; and
the routing patch comprises signal paths between the patch contacts that couple the first semiconductor die to the second semiconductor die; and

conductive interconnection structures coupled to the substrate bottom side; and
wherein the conductive interconnection structures laterally surround the routing patch;
wherein the routing patch comprises back-end-of-the-line interconnection layers and redistribution layers on a top side of the back-end-of-the-line interconnection layers;
wherein the back-end-of-the-line interconnection layers comprises one or more layers of inorganic dielectric material;
wherein the redistribution layers comprises one or more layers of organic dielectric material; and
wherein the patch top side comprises a top side of the redistribution layers.
