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.
