Abstract:
A semiconductor wafer, comprising:a semiconductor substrate;a first dielectric layer formed upon an upper surface of the semiconductor substrate, wherein the first dielectric layer has an opening extending therethrough;an electrically conductive structure formed within the opening and in electrical contact with the upper surface of the semiconductor substrate;a second dielectric layer formed over the first dielectric layer and the electrically conductive structure, wherein the second dielectric layer has a pair of laterally spaced vertical holes located above the electrically conductive structure and extending through the second dielectric layer;a pair of electrically conductive contact plugs, wherein each contact plug is formed within a respective one of said pair of vertical holes and extends between an upper surface of the second dielectric layer and an upper surface of the electrically conductive structure, and wherein each contact plug is in electrical contact with the electrically conductive structure; andan electrically conductive probe pad formed upon an upper surface of the second dielectric layer and extending between the pair of contact plugs, wherein the probe pad is in electrical contact with each contact plug.
