Abstract
Some embodiments relate to a semiconductor device manufacturing process. In the process, a substrate is provided, and a sacrificial layer is formed over the substrate. An opening is patterned through the sacrificial layer, and the opening is filled with conductive material. The sacrificial layer is removed while the conductive material is left in place. A first dielectric layer is formed along sidewalls of the conductive material that was left in place.
