Ruthenium Electrodeposition from Deep Eutectic Solvents [PDF]

open access: yesECS Meeting Abstracts, 2017
Ruthenium is one of the most promising materials for the realization of barrier/seed layers in low-k copper interconnects technology. It is a possible candidate for the substitution of materials like Ta/TaN or TiN. This metal presents interesting properties like a reasonably low resistivity (7.1 µΩcm in bulk), a high melting point and high mechanical
