A composition for cleaning and rust prevention which is for use in the step of producing, e.g., a semiconductor element having a metallic wiring containing copper. The composition comprises: an anticorrosive component comprising any of pyrazole, pyrazole derivatives such as 3,5-dimethylpyrazole, 1,2,4-triazole, triazole derivatives, aminocarboxylic acid compounds such as iminodiacetic acid and ethylenediaminedipropionic acid hydrochloride, and disulfides such as diisopropyl disulfide and diethyl disulfide; and a detergent component comprising any of ammonium fluoride, tetramethylammonium fluoride, ammonium acetate, acetic acid, glyoxylic acid, oxalic acid, ascorbic acid, 1,2-diaminopropane, and dimethylacetamide. Also provided is a process for producing a semiconductor element or the like using the composition for cleaning and rust prevention. |
