An electronic device may include a substrate, a seed layer on the substrate, a barrier layer on the seed layer opposite the substrate, and an oxidation barrier on the barrier layer opposite the seed layer. The barrier layer and the seed layer comprise different materials, and the oxidation barrier and the barrier layer may comprise different materials. The seed layer may be undercut relative to the barrier layer and/or relative to the oxidation barrier so that the barrier layer and/or the oxidation barrier define a lip extending beyond the seed layer in a direction parallel with respect to a surface of the substrate. Related methods are also discussed. |
