    摘要: 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 anmonium fluoride, 48.38 weight % of H2O and 48.5 weight % of diethylene glycol mono-n-buthl 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. It can propose a separation-material composition for a photo-resist such that the photo-resist residuals and the by-product polymer are easily removed after a dry etching process and at the same time the low dielectric-constant insulation film is avoided from erosion and oxidization.

    摘要: A photoresist stripping composition comprises (1) a nitrogen-containing organohydroxyl compound, (2) an alkylene glycol monoalkyl ether represented by the general formula: HO—(CpH2pO)q—R, wherein R is C1-C4 alkyl, p is 2 or 3, and q is 1, 2 or 3, (3) sugar or sugar alcohol, (4) a phosphorus-containing compound and (5) water. The photoresist stripping composition easily removes photoresist films on the inorganic substrate, and patterned photoresist films and photoresist residues remaining after etching and photoresist residues in a short period of time without corroding semiconductive materials, circuit-forming materials, insulating materials, etc.

    摘要: A cleaning agent for use in the manufacture of a semiconductor device comprising an aqueous solution containing a quarternary ammonium salt and a fluoro compound, or an aqueous solution containing a quarternary ammonium salt and a fluoro compound, as well as an organic solvent selected from the group consisting of amides, lactones, nitriles, alcohols and esters. In the semiconductor device manufacturing process, after forming a mask with a photoresist, a wiring structure is formed by dry etching of a conductive layer, wherein a protecting deposition film has been formed on side walls of the conductive layer. Use of the cleaning agent enables the protecting deposition film to be removed in a highly reliable manner with the surface of the conductive layer being decontaminated and cleaned such that no corrosion of the conductive layer occurs.
