Abstract[English]
are each independently a substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl, or cycloalkenyl group with 1 to 20 carbon atoms, or a substituted or unsubstituted aryl group with 6-20 carbon atoms, or an amine, cyclic amine, cyano, ether, cyclic ether, ester, cyclic ester, halide, nitro, silyl, thiol, or carbonyl group. A method of stabilization of organotin photoresist composition comprises adding an organic additive.[French]
L'invention concerne une composition de résine photosensible d'organoétain pour rayonnement actinique et un procédé de stabilisation. La composition de résine photosensible d'organoétain comprend un composé d'organoétain représenté par les formules chimiques [RSnOO]4Sn, [RSnOO]3SnR1, [RSnOO]2SnR1 2, [RSnOO]SnR1 3, [R3SnO]4Sn, [R3SnO]3SnR1, [R3SnO]2SnR1 2, [R3SnO]SnR1 3, ou R2Sn(µ-O)2Sn(µ-O)2SnR2, un solvant et un additif, R, R1 étant chacun indépendamment un groupe alkyle, alcényle, alcynyle, cycloalkyle ou cycloalcényle substitué ou non substitué ayant de 1 à 20 atomes de carbone, ou un groupe aryle substitué ou non substitué ayant de 6 à 20 atomes de carbone, ou un groupe amine, amine cyclique, cyano, éther, éther cyclique, ester, ester cyclique, halogénure, nitro, silyle, thiol ou carbonyle. Un procédé de stabilisation de la composition de résine photosensible d'organoétain comprend l'ajout d'un additif organique.
