Copper (Cu) has been used as the metal for interconnects for many years. Along with the continued scaling of semiconductor devices, especially beyond 10 nm nodes, alternative metals such as ruthenium (Ru) and molybdenum (Mo) have emerged as interesting candidates to replace Cu (1) at certain levels of the interconnect.
