Abstract: An electronic package comprises a substrate core; one or more dielectric material layers over the substrate core and having a lower dielectric material layer, and a plurality of metallization layers comprising an upper-most metallization layer; an integrated circuit (IC) die embedded within the dielectric material and below the upper-most metallization layer; and at least one conductive feature below and coupled to the IC die. A downwardly facing surface of the conductive feature is located on the lower dielectric material layer and defines a horizontal plane at a junction between the conductive feature and the lower dielectric material layer. The lower dielectric material layer has an upper facing surface facing in a direction of the IC die adjacent the conductive feature that is vertically offset from the horizontal plane.
