Abstract:
The present invention relates to an electrolyte composition for depositing copper on a conductive surface. The composition contains a combination of 2,2′-bipyridine, imidazole, tetra-ethyl-ammonium, and a complexing agent for copper. This electrolyte makes it possible to manufacture small size copper interconnects without any void and with a filling speed that is compatible with industrial constrain. The invention also concerns a process for filling cavities with copper, and a semiconductor device that is obtained according to this process.

Claim (Index 7):
The electrochemical process as claimed in  claim 5 , characterized in that a diffusion barrier layer is interposed between the dielectric substrate and the metal seed layer, said diffusion barrier layer comprising at least one material selected from the group consisting of tantalum (Ta), titanium (Ti), tantalum nitride (TaN), titanium nitride (TiN), manganese (Mn) and tungsten (W).
