Abstract:
Methods for removing a masking material, for example, a photoresist, and electronic devices formed by removing a masking material are presented. For example, a method for removing a masking material includes contacting the masking material with a solution comprising cerium and at least one additional oxidant. The cerium may be comprised in a salt. The salt may be cerium ammonium nitrate. The at least one additional oxidant may be a manganese, ruthenium, and/or osmium-containing compound.

Abstract:
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.
Abstract:
Compositions and methods of using the said composition for removing polymeric materials from surfaces, preferably cleaning contaminant buildup from a lithography apparatus without total disassembly of the said apparatus. The said compositions comprise at least one organic solvent and one non-ionic surfactant. Moreover, the pH of the said composition is about 5 to 9.

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 novel corrosion inhibitors. 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.
