In an exemplary embodiment, the method comprises receiving a substrate and depositing a first layer over the substrate. A copolymer layer that includes a first constituent polymer and a second constituent polymer is formed over the first layer. The first constituent polymer is selectively removed from the copolymer layer. A first region of the first layer corresponding to the selectively removed first constituent polymer is etched. The etching leaves a second region of the first layer underlying the second constituent polymer unetched. A metallization process is performed on the etched substrate, and the first layer is removed from the second region to form an air gap. The method may further comprise depositing a dielectric material within the etched first region.
