description A cleaning composition and process for cleaning post-chemical mechanical polishing (CMP) residue and contaminants from a microelectronic device having said residue and contaminants thereon. The cleaning compositions include at least one quaternary base, at least one amine, at least one corrosion inhibitor, and at least one solvent. The composition achieves highly efficacious cleaning of the post-CMP residue and contaminant material from the surface of the microelectronic device while being compatible with barrier layers.
