Semiconductor devices having a through-silicon-via and methods of forming the same are described herein. As an example, a semiconductor device may include a substrate material, a through-silicon-via protrusion extending from the substrate material, a first dielectric material formed on the substrate material, a second dielectric material formed on the first dielectric material, and an interconnect formed on the through-silicon-via protrusion, where the interconnect formed is in an opening in the second dielectric material.
