摘要: A cleaning liquid for lithography that is capable of removing residual material which remains after an etching process, as well as suppressing corrosion of at least one of cobalt and alloys thereof, and a method for cleaning a substrate using the cleaning liquid. The cleaning liquid for lithography includes hydroxylamine, at least one basic compound selected from amine compounds other than hydroxylamine, and quaternary ammonium hydroxides, and water, and has a pH value of 8 or higher. The cleaning liquid is used in cleaning a substrate containing at least one of cobalt and alloys thereof.
