Abstract:
A plasma etch-resistant photoresist composition comprised of:(a) an organotitanium polymer or organotitanium copolymer produced by reacting:a poly(alkyltitanate) or a poly(alkyltitanate-co-alkylmetallate) or mixtures thereof wherein the alkyl groups of the poly(alkyltitanate) or poly(alkyltitanate-co-alkylmetallate) are bonded to respective oxygen atoms which are bonded to the titanium atom of the poly(alkyltitanate) or poly(alkyltitanate-co-alkylmetallate), withaddition polymerizable beta-diketones, beta-ketoesters, alpha-hydroxy carboxylic acid salts, alpha-hydroxy carboxylic acid esters or mixtures thereof; and(b) a solvent vehicle suitable for obtaining high quality thin films on device substrates by spin casting.
