Abstract: Structures with improved solder bump connections and methods of fabricating such structures are provided herein. The structure includes a trench formed in a dielectric layer which has at least a portion (12) thereof devoid of a fluorine boundary layer. The structure further includes a copper wire (20) in the trench having at least a bottom portion thereof in contact with the non- fluoride boundary layer (12) of the trench. A lead free solder bump (34) is in electrical contact with the copper wire (20).
