Abstract:
A liquid removal composition and process for removing photoresist and/or sacrificial anti-reflective coating (SARC) material from a microelectronic device having same thereon. The liquid removal composition includes at least one organic quaternary base and at least one surface interaction enhancing additive. The composition achieves at least partial removal of photoresist and/or SARC material in the manufacture of integrated circuitry with minimal etching of metal species on the microelectronic device, such as copper and cobalt, and without damage to low-k dielectric materials employed in the microelectronic device architecture.

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.
