Abstract:
Cleaning compositions and processes for cleaning post-plasma etch residue from a microelectronic device having said residue thereon. The composition achieves highly efficacious cleaning of the residue material, including titanium-containing, copper-containing, tungsten-containing, and/or cobalt-containing post-etch residue from the microelectronic device while simultaneously not damaging the interlevel dielectric, metal interconnect material, and/or capping layers also present thereon. In addition, the composition may be useful for the removal of titanium nitride layers from a microelectronic device having same thereon.
Abstract:
Removal compositions and processes for removing at least one material layer from a rejected microelectronic device structure having same thereon. The removal composition includes hydrofluoric acid. The composition achieves substantial removal of the material(s) to be removed while not damaging the layers to be retained, for reclaiming, reworking, recycling and/or reuse of said structure.
Abstract:
A method and self assembled monolayer (SAM)-containing compositions for removing bulk and hardened photoresist material from microelectronic devices have been developed. The SAM-containing composition includes at least one solvent, at least one catalyst, at least one SAM component, and optionally a surfactant. The SAM-containing compositions effectively remove the hardened photoresist material while simultaneously passivating the underlying silicon-containing layer(s) in a one step process.
Abstract:
A method and composition for removing copper-containing post-etch and/or post-ash residue from patterned microelectronic devices is described. The removal composition includes a diluent, a solvent and a copper corrosion inhibitor, wherein the diluent may be a dense fluid or a liquid solvent. The removal compositions effectively remove the copper-containing post-etch residue from the microelectronic device without damaging exposed low-k dielectric and metal interconnect materials.

Abstract:
A method and composition for removing bulk and ion-implanted photoresist and/or post-etch residue material from densely patterned microelectronic devices is described. The composition includes a co-solvent, a chelating agent, optionally an ion pairing reagent, and optionally a surfactant. The composition may further include dense fluid. The compositions effectively remove the photoresist and/or post-etch residue material from the microelectronic device without substantially over-etching the underlying silicon-containing layer(s) and metallic interconnect materials.
Abstract:
A method and composition for removing hardened photoresist, post-etch photoresist, and/or bottom anti-reflective coating from a microelectronic device is described. The composition may include a dense fluid, e.g., a supercritical fluid, and a dense fluid concentrate including a co-solvent, optionally a fluoride source, and optionally an acid. The dense fluid compositions substantially remove the contaminating residue and/or layers from the microelectronic device prior to subsequent processing, thus improving the morphology, performance, reliability and yield of the microelectronic device.
