Abstract:
A radiation-sensitive mixture including a film-forming polymer functionalized with 1,2-dicarboxylic acid monoester groups, comprising an acid-labile, hydrolysis-stable polymer unit (A) of structure: ##STR7## a thermally stable polymer unit (B) of structure: ##STR8## a second thermally stable polymer unit (C) of structure ##STR9## and a polymer unit (D) bearing reactive groups and having a structure ##STR10## in which the amount of (A) is from 1 to 99 mol %, the amount of (B) is from 1 to 99 mol %, the amount of (C) is from 0 to 50 mol %, and the amount of (D) is from 0 to 50 mol %, provided that the amounts of (A), (B), (C), and (D) total 100 mol %; and in whichn=0, 1, 2 or 3;R.sup.1 is a hydrocarbon radical bonded via a tertiary C atom to the O atom and having a total of 4 to 10 C atoms, or a 2-tetrahydrofuranyl or 2-tetrahydropyranyl radical;R.sup.2, R.sup.3 and R.sup.4 --independently of one another--are C.sub.1- to C.sub.6- alkyl or C.sub.1- to C.sub.6- alkoxy, C.sub.6- to C.sub.18- aryl or C.sub.6- to C.sub.18- aryloxy or aralkyl having a C.sub.6- to C.sub.18- aryl group and a C.sub.1- to C.sub.4- alkylene radical;R.sup.5 is H or C.sub.1- to C.sub.6- alkyl;R.sup.6, R.sup.7, R.sup.8 and R.sup.9 --independently of one another--are H, C.sub.1- to C.sub.6- alkyl, C.sub.6- to C.sub.18- aryl, halogen, CN, methoxyphenyl or a radical of structure ##STR11## where R.sup.15 is H, C.sub.1- to C.sub.6- alkyl, C.sub.6- to C.sub.18- aryl, CH.sub.2 .dbd.CH--, CH.sub.2 .dbd.CH--CH.sub.2 --, or CH.sub.2 .dbd.CH--CO--;R.sup.10 is H, C.sub.1- to C.sub.6- alkyl, C.sub.2- to C.sub.6- alkenyl, C.sub.6- to C.sub.18- aryl, halogen or halogen-substituted C.sub.1- to C.sub.6- alkyl;R.sup.11 and R.sup.12 --independently of one another--are linear C.sub.1- to C.sub.18- alkyl;R.sup.13 and R.sup.14 --independently of one another--are linear C.sub.1- to C.sub.18- alkyl or tert-butyl;X is Si or Sn, andY is O or NH;a radiation sensitive compound liberating an acid upon irradiation,a solvent, and optionally at least one additive.
