Claim:
1. A method, comprising: attaching a conductive ribbon to a first conductive pad that is disposed over a substrate; forming a layer of packaging material over the ribbon; removing a portion of the layer to form a first surface of the layer and a second surface of the layer that is approximately orthogonal to the first surface of the layer, the removing the portion of the layer exposing a first contact surface of the ribbon that is approximately coplanar with the first surface of the layer and exposing a second exposed contact surface of the ribbon that is approximately coplanar with the second surface of the layer to form a contact region including the first and second contact surfaces; wherein attaching the conductive ribbon includes: wherein removing the portion of the layer includes removing the portion of the layer to expose the midsection of the ribbon; removing a portion of the midsection to form the contact region; cutting through the midsection of the ribbon, the layer of packaging material, and the substrate to form an integrated circuit; forming a cavity through the contact region; and forming a conductive T-shaped filler structure in the cavity, the T-shaped filler structure including a vertical portion extending within the cavity and horizontal portions extending on the contact region.
