Abstract: An electronic device may include a bottom interconnect layer and an integrated circuit (IC) carried by the bottom interconnect layer. The electronic device may further include an encapsulation material on the bottom interconnect layer and laterally surrounding the IC. The electronic device may further include electrically conductive pillars on the bottom interconnect layer extending through the encapsulation material. At least one electrically conductive pillar and adjacent portions of encapsulation material may have a reduced height with respect to adjacent portions of the IC and the encapsulation material and may define at least one contact recess. The at least one contact recess may be spaced inwardly from a periphery of the encapsulation material.
