Zusammenfassung: | PURPOSE:To provide a surface processing agent capable of evenly surface processing even into fine region further avoiding the metallic pollution by a chemical solution by a method wherein water solution of exceeding one kind of elements out of HF, NH3, H2O2 or specific amount of specific interface activator is added to water. CONSTITUTION:Within the surface processing agent wherein a specific interfacial activator is added to a water solution or water comprising at least one kind of element selected out of l-200ppm of HF, NH3, H2O2, the interfacial activator is an organic compound having the composition mentioned as follows. The composition of the interfacial activator is to be R-(O-CnHzn)mC00H, R-(O- CnHzn)mCOOH, R-(O-CnHzn)mNH2 or R-(O-CnHzn)mOH, where a saturated hydrocarbon: in carbon number of 1-10, n: 1, 2 or 3, m:1 or 2, interfacial activator compound: e.g. CH3 (CH2)3 OCH2CH2 COOH, C4H9O(CH2)3 NH2, C2H5 OCH2CH2OH etc. |
