Abstract

The present invention relates to a copper electroplating bath composition and method of using it for microelectronic device fabrication. In particular, the present invention relates to cooper electroplating in the fabrication of interconnect structures in semiconductor devices. By use of the inventive copper eletroplating bath composition, the incidence of voids in the interconnect structures is reduced.
