Patent ID: 6982386

Claim:
A microelectronic device, comprising: a microelectronic die having an integrated circuit and a plurality of bond-pads coupled to the integrated circuit; an interconnecting substrate coupled to the microelectronic die, the interconnecting substrate having a first external layer, a second external layer, a first conductive stratum between the first and second external layers, a first dielectric separator layer having a first surface contacting the first conductive stratum, a plurality of contact elements on at least one of the first and second external layers coupled to corresponding bond-pads on the die, a plurality ball-pads on at least one of the first and second external layers, and a plurality of trace lines electrically coupling selected contact elements to corresponding ball-pads, wherein the first conductive stratum has an internal moisture release element, and wherein at least one of the contact elements is coupled to the first conductive stratum; and a protective casing covering at least a portion of the microelectronic die.
