    摘要: 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 co-solvent species, to achieve high-efficiency removal of photoresist and/or SARC 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 the semiconductor architecture.

    摘要: A method and composition for removing ion-implanted photoresist from semiconductor substrates having such photoresist is described. The removal composition contains supercritical CO2 (SCCO2), a co-solvent and a reducing agent for use in removing ion-implanted photoresist. Such removal composition overcomes the intrinsic deficiency of SCCO2 as a removal reagent, viz., the non-polar character of SCCO2 and its associated inability to solubilize species such as inorganic salts and polar organic compounds that are present in the photoresist and that must be removed from the semiconductor substrate for efficient cleaning.
