Abstract:
An electrically conductive structure in an integrated circuit (IC) includes a bottom metal line and a top metal line with via providing electrical interconnection between the bottom metal line and the top metal line. The via is fully aligned with both the bottom metal line and the top metal line. An electrically conductive material fills an opening formed in a dielectric material to form the via, and the electrically conductive material is directly in contact with the bottom metal line. No diffusion barrier layer and/or liner layer is between the bottom metal line and the via.

Claim (Index 18):
The method of  claim 15 , wherein forming the via comprises:\n forming a trench and an opening through the interlayer dielectric and the conformal dielectric layer, wherein the opening extends from a bottom of the trench to the top surface of the first metal line; and filling the opening with the electrically conductive material to form the via.
