Abstract:
A method is provided that includes forming 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 stops on the first dielectric material, and exposing a portion of the conductive or semiconductive features. Numerous other aspects are provided.
