Abstract:
A composition and method for removing copper-containing post-etch and/or post-ash residue from patterned microelectronic devices is described. The removal composition includes water, a water-miscible organic solvent, an amine compound, an organic acid, and a fluoride ion source. The compositions effectively remove the copper-containing post-etch residue from the microelectronic device without damaging exposed low-k dielectric and metal interconnect materials.
