Abstract
A method and electronic device are provided. The method includes patterning a metal in a first dielectric layer, depositing a first metal layer over the patterned metal, forming a nanowall under the first metal layer such that the nanowall is in contact with the patterned metal in the first dielectric layer, depositing a second dielectric layer on the first dielectric layer, removing at least a portion of the nanowall, thereby forming a channel in the second dielectric layer, and depositing a metal via in the channel such that the metal via is in contact with the patterned metal in the first dielectric layer.
