A metal interconnect structure is doped with zinc, indium, or gallium using top-down doping processes to improve diffusion barrier properties with minimal impact on line resistance. Dopant is introduced prior to metallization or after metallization. Dopant may be introduced by chemical vapor deposition on a liner layer at an elevated temperature prior to metallization, by chemical vapor deposition on a metal feature at an elevated temperature after metallization, or by electroless deposition on a copper feature after metallization. Application of elevated temperatures causes the metal interconnect structure to be doped and form a self-formed barrier layer or strengthen an existing diffusion barrier layer.
