Patent ID: 8742572

Claim:
A plurality of microelectronic devices, comprising: a rigid substrate having a plurality of holes arranged in arrays and a plurality of conductive traces, the substrate having a first side and a second side opposite from the first side; a first conductive material having a first surface facing the first side of the substrate, and a second surface facing away from the first surface; a second conductive material having a first face and a second face facing away from the first face, the first face directly containing the second surface of the first material, and the second conductive material at least partially conforming to the individual holes; a plurality of electrical couplers directly contacting corresponding traces at the first side of the substrate; and a plurality of singulated microelectronic dies at the second side of the substrate, the individual dies including an active side facing toward the substrate, a plurality of terminals disposed on the active side and aligned with corresponding holes, a back side opposite the active side, and a plurality of ends extending between the active side and the back side, wherein the second conductive material directly contacts the individual terminals.
