PACKAGE COMPRISING A SUBSTRATE WITH HIGH-DENSITY INTERCONNECTS

A package comprising a substrate and an integrated device coupled to the substrate. The substrate includes a core layer comprising a first surface and a second surface; at least one first dielectric layer coupled to the first surface of the core layer; at least one second dielectric layer coupled to the second surface of the core layer; at least one core interconnect that extends through the core layer and at least one dielectric layer from the at least first dielectric layer and/or the at least one second dielectric layer; a plurality of high-density interconnects comprising a first minimum width and a first minimum spacing; and a plurality of interconnects comprising a second minimum width and a second minimum spacing. The second minimum width is greater than the first minimum width. The second minimum spacing is greater than the first minimum spacing.
