Abstract:
A method of fabricating at least one metal interconnect, comprising the steps of:providing a structure having at least one exposed conductive structure; forming a non-stick material layer over the structure and the at least one exposed conductive structure; the non-stick material layer having an upper surface; patterning the non-stick material layer to form a patterned non-stick material layer having at least one trench therethrough exposing at least a portion of the at least one conductive structure; forming a metal interconnect in contact with the exposed portion of the at least one conductive structure within the at least one trench wherein the non-stick properties of the patterned non-stick material layer prevent accumulation of the metal comprising the metal interconnect upon the patterned upper surface of the patterned non-stick material layer; the at least one metal interconnect having an upper surface; removing the patterned non-stick material layer; and forming a planarized dielectric layer over the structure exposing the upper surface of the at least one metal interconnect.
