Abstract:
A composition including supercritical fluid and at least one additive selected from fluoro species, and primary and/or secondary amines, optionally with co-solvent, low k material attack-inhibitor(s) and/or surfactant(s). The composition has particular utility for cleaning of semiconductor wafers to remove post-ashing residues therefrom.
Abstract:
Removal compositions and processes for removing at least one material layer from a rejected microelectronic device structure having same thereon. The removal composition preferably 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. Processes include the monitoring and modifying said compositions.

Abstract:
A composition and process for wet stripping removal of sacrificial anti-reflective silicate material, e.g., from a substrate or article having such material deposited thereon, particularly where the sacrificial anti-reflective material is present with permanent silicate materials desired to be unaffected by the wet stripping composition.
Abstract:
A semi-aqueous cleaning formulation useful for removing particles from semiconductor wafer substrates formed during a dry etching process for semiconductor devices, the cleaning formulation comprising a buffering system a polar organic solvent, and a fluoride source.

Abstract:
A composition and process for removing photoresist and/or sacrificial anti- reflective coating (SARC) materials from a substrate having such material(s) thereon. The composition includes a base component, such as a quaternary ammonium base in combination with an alkali or alkaline earth base, or alternatively a strong base in combination with an oxidant. The composition may be utilized in aqueous medium, e.g., with chelator, surfactant, and/or c o- solvent species, to achieve high-efficiency removal of photoresist and/or SA RC materials in the manufacture of integrated circuitry, without adverse effect on metal species on the substrate, such as copper, aluminum and/or cobalt alloys, and without damage to SiOC-based dielectric materials employed in th e semiconductor architecture.
