Claim 14:
15. A structure for circuit interconnects, comprising:
a first grounding plane;
a second grounding plane beneath the first grounding plane;
a substrate layer of dielectric material between the first grounding plane and the second grounding plane;
a trace embedded in the substrate layer;
a pillar above the first grounding plane;
a via structure extending through the first grounding plane, the via structure comprising a first end portion connected to the pillar and a second end portion connected to the trace; and
a group of metallic structures embedded in the substrate layer directly beneath the second end portion of the via structure and separated from the second end portion of the via structure by the dielectric material, the group of metallic structures and the trace having a same width to decrease an impedance difference between the via structure and the trace;
wherein the group of metallic structures and a portion of the trace that is connected to the via structure have a same perpendicular width that is perpendicular to the trace; and
wherein the group of metallic structures further has a parallel width that is the same as the perpendicular width, the parallel width being a width of the group of metallic structures that is parallel to the trace.
