    摘要: An aqueous ammonia composition having low surface tension is disclosed, which comprises ammonia water and a fluoroalkylsulfonamide compound having the following general formula:R.sup.1 SO.sub.2 NR.sup.2 --X--H (I)wherein R.sup.1 represents a fluoroalkyl group, R.sup.2 represents a hydrogen atom or a lower alkyl group, X represents a grouping selected from CH.sub.2 COO and (CH.sub.2 CH.sub.2 O).sub.n, wherein n is a positive integer from 1 to 20. This aqueous ammonia composition may be mixed with an aqueous hydrogen peroxide solution and water so that it can be used for cleaning a semiconductor substrate. The cleaning solution has outstanding stability, and exhibits improved efficacy in removing microparticles of impurities and excellent surface-protecting effect on the semiconductor substrate that is useful in the manufacture of high density integrated circuit elements.
