Copper Interconnect
The conventional technology that uses copper as the conductive wiring for chip interconnects. At extremely narrow line widths it faces physical limits owing to deteriorating resistivity and is being evaluated for replacement by alternative materials such as ruthenium.

Intel Labs is evaluating ruthenium as an alternative to copper interconnects, because ruthenium can form wires through etching rather than electroplating, eliminating the barrier layer.
