Abstract
A method includes forming a first metallization layer on a substrate comprising a plurality of conductive lines. The method further includes forming a first dielectric layer on the substrate and between adjacent conductive lines. The method further includes forming a first via layer comprising at least one via in the first dielectric layer and exposing a top surface of at least one of the plurality of conductive lines. The method further includes depositing a first conductive material in the first via. The method further includes forming a barrier layer on a top surface of the first dielectric layer and exposing a top surface of the plurality of conductive lines and the first conductive material.
