Non-amine post-CMP compositions and method of use

Last updated:

Abstract:

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.
