Claim Text:
1. A structure comprising: a metallic structure positioned within an interconnect level above a substrate, the metallic structure being adjacent to a kerf of the substrate; a first dielectric layer above the interconnect level, the first dielectric layer comprising an opening aligned with and above the metallic structure; a metallic liner above the first dielectric layer, within the opening, and on the metallic structure; a second dielectric layer above the metallic liner; a third dielectric layer above the second dielectric layer, the third dielectric layer being thicker than either the first dielectric layer or the second dielectric layer; a conductive pad within the interconnect level, the first dielectric layer further comprising a second opening aligned with and above the conductive pad and the metallic liner further being within the second opening and on the conductive pad; a copper plug on the metallic liner above the conductive pad; a copper pedestal on the copper plug; and a solder structure on the copper pedestal.
