NESTED INTERCONNECT STRUCTURE IN CONCENTRIC ARRANGEMENT FOR IMPROVED PACKAGE ARCHITECTURE

Abstract:

An integrated circuit (IC) package is described. The IC package includes back-end-of-line layers on a substrate. The IC package also includes a nested interconnect structure on the back-end-of-line layers on the substrate. The nested interconnect structure is composed of an inner core pad and an outer ring pad in a concentric arrangement. The IC package further includes a redistribution layer on the nested interconnect structure. The IC package also includes an under bump metallization layer on the redistribution layer to support package balls.
