Claim 10:
11. An integrated circuit structure, comprising:
a dielectric material, the dielectric material comprising silicon, oxygen and carbon;
a trench in the dielectric material, the trench having a bottom and sidewalls;
a first material within the trench, the first material comprising copper, and the first material having a bottom surface, sidewall surfaces and a top surface;
a second material on the bottom surface, along the sidewall surfaces and on the top surface of the first material in a cross-section perspective, the second material comprising cobalt, wherein at least a portion of the second material on the top surface of the first material is within the trench in the dielectric material; and
a third material between the bottom of the trench and the second material, the third material between the sidewalls of the trench and the second material, and the third material comprising tantalum.
