    摘要: The fuel-barrier polyamide resin of the present invention is a product of the polycondensation of a diamine component comprising 70 mol % or higher of m-xylylenediamine and a dicarboxylic acid component comprising 70 mol % or higher of a mixed dicarboxylic acid which comprises a C4 to C20 α,ω-linear aliphatic dicarboxylic acid and at least one dicarboxylic acid selected from the group consisting of isophthalic acid and naphthalenedicarboxylic acid in a molar ratio of 30:70 to 95:5. The polyamide resin is excellent in not only fuel-barrier property and heat resistance, but also moldability and recyclability, and therefore suitably used as a barrier material of fuel containers.

    摘要: Stripping and cleaning agent for removing dry-etching photoresist residues, and a method for forming an aluminum based line pattern using the stripping and cleaning agent. The stripping and cleaning agent contains (a) from 5 to 50% by weight of an organocarboxlic ammonium salt or an amine carboxylate, represented by the formula [R.sup.1 ]m[COONH.sub.p (R.sup.2)q]n, where R.sup.1 is hydrogen, or an alkyl or aryl group having from 1 to 18 carbon atoms; R.sup.2 is hydrogen, or an alkyl group having from 1 to 4 carbon atoms; m and n independently are integers of from 1 to 4, p is integer of from 1 to 4, q is integer of from 1 to 3, and p+q=4 and (b) from 0.5 to 15% by weight of a fluorine compound. The inventive method is advantageously applied to treating a dry-etched semiconductor substrate with the stripping and cleaning agent. The semiconductor substrate comprises a semiconductor wafer having thereon a conductive layer containing aluminum. The conductive layer is dry-etched through a patterned photoresist mask to form a wiring body having etched side walls. The dry etching forms a side wall protection film on the side walls. In accordance with the inventive method, the side wall protection film and other resist residues are completely released without corroding the wiring body.
