Abstract:
Structures with improved solder bump connections and methods of fabricating such structures are provided herein. The method includes forming a plurality of trenches in a dielectric layer extending to an underlying metal layer. The method further includes depositing metal in the plurality of trenches to form discrete metal line islands in contact with the underlying metal layer. The method also includes forming a solder bump in electrical connection to the plurality of metal line islands.
