In a first aspect, a method is provided that includes: forming a plurality of conductive or semiconductive features above a first dielectric material; depositing a second dielectric material above the conductive or semiconductive features; etching a void in the second dielectric material, wherein the etch is selective between the first and the second dielectric material and the etch stops on the first dielectric material; and exposing a portion of the conductive or semiconductive features. Numerous other aspects are provided.
