Claim 0:
1. 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 core material within the trench, the core material comprising copper, and the core material having a bottom surface, sidewall surfaces and a top surface;
a jacket on the bottom surface, along the sidewall surfaces and on the top surface of the core material in a cross-section perspective, the jacket comprising cobalt, wherein at least a portion of the jacket on the top surface of the core material is within the trench in the dielectric material; and
a barrier layer between the bottom of the trench and the jacket, the barrier layer between the sidewalls of the trench and the jacket, and the barrier layer comprising tantalum.
