Claim:
1. A semiconductor structure comprising: a metal layer disposed within a first dielectric layer over a substrate; a second dielectric layer over the metal layer; and at least one conductive contact including a first conductive contact and a second conductive contact, each of the first conductive contact and the second conductive contact having a first portion extending into the metal layer and a second portion disposed within the second dielectric layer, wherein the first portion of each of the first conductive contact and the second conductive contact includes a first material that is the same as a second material of the second portion of each of the first conductive contact and the second conductive contact, and wherein the first portion of each of the first conductive contact and the second conductive contact extend into a substantial portion of the metal layer such that the first portion of each of the first conductive contact and the second conductive contact define a continuous material underneath the second dielectric layer from the second portion of the first conductive contact to the second portion of the second conductive contact.
