A cleaning composition and process for cleaning an in-process microelectronic device substrate, e.g., by post-chemical mechanical polishing (CMP) cleaning, to remove residue from a surface thereof, wherein the cleaning composition may be especially effective for cleaning a substrate surface that includes exposed metal such as cobalt, copper, or both, along with dielectric or low k dielectric material, and wherein the cleaning composition includes corrosion inhibitor to inhibit corrosion of the exposed metal.

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 are substantially devoid of alkali hydroxides, alkaline earth metal hydroxides, and tetramethylammonium hydroxide. The composition achieves highly efficacious cleaning of the post-CMP residue and contaminant material from the surface of the microelectronic device without compromising the low-k dielectric material or the copper interconnect material.
An amine-free composition and process for cleaning post-chemical mechanical polishing (CMP) residue and contaminants from a microelectronic device having said residue and contaminants thereon. The compositions achieve highly efficacious cleaning of the post-CMP residue and contaminant material from the surface of the microelectronic device without compromising the low-k dielectric material, copper interconnect material, or cobalt-containing materials.
