Abstract

Methods of forming an electronic structure may include forming a seed layer on an electronic substrate, and forming a conductive shunt layer on portions of the seed layer wherein portions of the seed layer are free of the conductive shunt layer. A conductive barrier layer may be formed on the conductive shunt layer opposite the seed layer wherein the conductive shunt layer comprises a first material and wherein the barrier layer comprises a second material different than the first material. Moreover, a solder layer may be formed on the barrier layer opposite the conductive shunt layer wherein the solder layer comprises a third material different than the first and second materials. Related structures are also discussed.
