Abstract:
An interconnect dielectric material having an opening formed therein is first provided. A surface nitridation process is then performed to form a nitridized dielectric surface layer within the interconnect dielectric material. A metal layer is formed on the nitridized dielectric surface layer and then an anneal is performed to form a metal nitride layer between the metal layer and the nitridized dielectric surface layer. A portion of the originally deposited metal layer that is not reacted with the nitridized dielectric surface is then selectively removed and thereafter an electrical conducting structure is formed directly on the metal nitride layer that is present in the opening.

Claim (Index 19):
A semiconductor structure comprising:\n an interconnect dielectric material layer composed of an interconnect dielectric material and having a metal nitride liner and an electrical conducting structure embedded therein, wherein a nitridized dielectric surface of the interconnect dielectric material is located entirely between the metal nitride liner and the interconnect dielectric material layer, and the metal nitride liner is located between the electrical conducting structure and the nitridized dielectric surface of the interconnect dielectric material, and further wherein the electrical conducting structure has a topmost surface that is coplanar with a topmost surface of each of the metal nitride liner, the nitridized dielectric surface and the interconnect dielectric material layer, and the nitridized dielectric surface is composed of the interconnect dielectric material with added nitrogen.
