Patent ID: 11948808
Assignee: AMKOR TECHNOLOGY SINGAPORE HOLDING PTE. LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method of manufacturing a semiconductor device, the method comprising:
forming, on a carrier top side of a carrier, layers of an upper signal distribution structure;
coupling a bottom side of a semiconductor component to a top side of the upper signal distribution structure; and
after coupling the semiconductor component, forming, on a bottom side of the upper signal distribution structure, layers of a lower signal distribution structure;
wherein the layers of the lower signal distribution structure include a first dielectric layer and a first conductive layer;
wherein the first conductive layer of the lower signal distribution structure extends into a first opening in the first dielectric layer of the lower signal distribution structure and towards the upper signal distribution structures;
wherein the lower signal distribution structure comprises an under bump metal structure that has a concave shape that opens downward;
wherein the under bump metal structure comprises a bump upper side and a bump lower side; and
wherein the bump upper side is coupled to a bottom side of the lower signal distribution structure.
