Abstract

Official abstract text for this publication.

The present disclosure provides one embodiment of a method to form an interconnect structure. The method includes forming a first dielectric material layer on a substrate; patterning the first dielectric material layer to form a plurality of vias therein; forming a metal layer on the first dielectric layer and the substrate, wherein the metal layer fills in the plurality of vias; and etching the metal layer such that portions of the metal layer above the first dielectric material layer are patterned to form a plurality of metal lines, aligned with plurality of vias, respectively.

First claim

Opening claim text (preview).

What is claimed is: 1. A method, comprising: forming a first dielectric material layer on a substrate; patterning the first dielectric material layer to form a plurality of vias therein; forming a first barrier layer of a first material in the plurality of vias and on the first dielectric material layer; forming a metal layer, contacting the first barrier layer, on the first dielectric layer and the substrate, wherein a portion of the metal layer fills the plurality of vias…
