Abstract:
Back end of line (BEOL) stripping solutions which can be used in a stripping process that replaces etching resist ashing process are provided. The stripping solutions are useful for fabricating circuits and/or forming electrodes on semiconductor devices for semiconductor integrated circuits with good efficiency and with low and acceptable metal etch rates. Methods for their use are similarly provided. The preferred stripping agents contain a polar aprotic solvent, water, an amine and a quaternary hydroxide that is not tetramethylammonium hydroxide. Further provided are integrated circuit devices and electronic interconnect structures prepared according to these methods.
