3D-INTERCONNECT

A method of making a microelectronic package includes bonding a conductive structure to a carrier so that the conductive structure overlies a rear surface of a microelectronic element disposed on the carrier and an exposed top surface of the carrier. The conductive structure may be a monolithic structure having a base and a plurality of interconnections extending continuously away from the base toward the carrier. The plurality of interconnections may have free ends that overlie the carrier. The microelectronic element may be positioned between at least two adjacent interconnections of the plurality of interconnections. The plurality of interconnections and the microelectronic element may be encapsulated with an encapsulant. The carrier may be removed to expose the free ends of the interconnections and bond pads of the microelectronic element. The free ends of the interconnections and the bond pads of the microelectronic element may be conductively connected with the terminals of the microelectronic package. The conductive structure may be patterned to form external contacts. At least some of the external contacts may overlie the microelectronic element.
