Abstract

Methods of manufacturing a semiconductor device include forming a conductive layer on a substrate, forming an air gap or other cavity between the conductive layer and the substrate, and patterning the conductive layer to expose the air gap. The methods may further include forming conductive pillars between the substrate and the conductive layer. The air gap may be positioned between the conductive pillars.
