| description | The present invention relates to a nonaqueous stripper composition for negative chemically amplified resists which shows excellent removing capabilities, has anticorrosive effects on varieties of metallic substrate plates such as Al, W, TiN, WSi, SiON, SiNx, HTO, etc., improves productivity since it can be recycled as a nonaqueous stripper even after many applications, and is suitable in electronic material fields in which high precision processing is required in the negative chemically amplified resist removing process. The present invention provides a stripper composition for negative chemically amplified resists comprising a) 20 to 35 weight % of straight chained alkylbenzenesulfonic acid; b) 10 to 34 weight % of light aromatic naphtha solvent; c) 30 to 45 weight % of organic compounds containing chlorine; d) 15 to 25 weight % of hydroxybenzenes; and e) 0.5 to 5 weight % of polyoxyethylene octylphenylether derivatives, in order to accomplish the above objects. |
