Abstract
Selective ruthenium and selective ruthenium oxide may be used in single damascene processes and/or dual damascene processes to form BEOL metallization layers and vias of an electronic device. A selective ruthenium liner may be formed to achieve a low contact resistance and a low sheet resistance for the BEOL metallization layers and vias, to promote adhesion between the various layers and materials in the BEOL metallization layers and vias, and/or to reduce or eliminate defects (such as voids and discontinuities) in the BEOL metallization layers and vias.
