4. The electronic package of claim 1 , further comprising a solder joint coupled to the first through-silicon via and physically coupled to the lead of the mount, and wherein the solder joint is selected from the group consisting of controlled collapse chip connection and eutectic solder.
5. The electronic package of claim 1 , further comprising a solder joint coupled to the first through-silicon via and coupled to the silicon spacer, and wherein the solder joint is selected from the group consisting of controlled collapse chip connection and eutectic solder.
6. The electronic package of claim 1 , wherein the redirect path includes one or more functional units adapted to modify the signal, wherein at least one of the one or more functional units is selected from the group consisting of a logic device; and an analog device.
7. The electronic package of claim 1 , wherein the lead is physically coupled to the first through-silicon via by a solder joint.
8. The electronic package of claim 1 , further comprising:
a dielectric layer formed on a surface of the first through-silicon via;
an adhesion layer formed on the dielectric layer;
an interconnect contact material formed on the adhesion layer; and
a cavity fill material formed on the interconnect contact material.
9. The electronic package of claim 1 , wherein the redirect path includes one or more functional units adapted to modify the signal, the one or more functional units having a logic device and an analog device.
10. The electronic package of claim 1 , further comprising a solder joint coupled to the silicon spacer and coupled to the second through-silicon via, and wherein the solder joint is selected from the group consisting of controlled collapse chip connection and eutectic solder.
11. A system comprising:
an electronic package, comprising:
a mount having a lead;
