Abstract
A semiconductor structure includes a substrate, at least one electrically conductive pillar provided over the substrate and an electrically conductive structure provided over the substrate. The electrically conductive pillar includes an inner portion and an outer layer that is provided below the inner portion and lateral to the inner portion. The electrically conductive structure also includes an inner portion and an outer layer that is provided below the inner portion and lateral to the inner portion. The electrically conductive structure annularly encloses each of the at least one electrically conductive pillar. The outer layer of each of the at least one electrically conductive pillar contacts the outer layer of the electrically conductive structure. The outer layer of the at least one electrically conductive pillar and the outer layer of the electrically conductive structure are formed of different metallic materials.
