Abstract: One example of a separation-material composition for a photo-resist according to the present invention comprises 5.0 weight % of sulfamic acid, 34.7 weight % of H2O, 0.3 weight % of ammonium 1-hydrogen difluoride, 30 weight % of N,N-dimethylacetamide and 30 weight % of diethylene glycol mono-n-buthyl ether. Another example of a separation-material composition for a photo-resist according to the present invention comprises 1-hydroxyethylidene-1, 3.0 weight % of 1-diphosphonic acid, 0.12 weight % of ammonium fluoride, 48.38 weight % of H2O and 48.5 weight % of diethylene glycol mono-n-buthyl ether. The separation-material composition for the photo-resist is mainly used for a medicinal liquid washing liquid/scientific liquid in order to remove the photo-resist residuals and the by-product polymer after an ashing process of a photo-resist mask.
