Patent ID: 7550247

Claim:
A resist composition comprising: (A) a silicone resin, (B) a photoacid generator, (C) a nitrogen-containing organic compound, and (D) a solvent, said silicone resin (A) being obtained through cohydrolytic condensation of a mixture comprising hydrolyzable silane monomers having the general formulae (1), (2) and (3) and another hydrolyzable monomer having at least two hydrolyzable substituent groups: R 1 R 2 p SiX 3−p (1) R 3 R 4 q SiX 3−q (2) R 5 R 6 r SiX 3−r (3) wherein R 1 is a C 3 -C 20 organic group with a straight, branched, cyclic or polycyclic structure which has a hydroxyl group on a carbon atom as a functional group, which has at least 3 fluorine atoms, in total, on a carbon atom bonded to the hydroxyl-bonded carbon atom, and which may further contain a halogen, oxygen or sulfur atom, R 2 is a C 1 -C 6 hydrocarbon group having a straight, branched or cyclic structure, R 3 is a C 3 -C 20 organic group with a straight, branched, cyclic or polycyclic structure which has a carboxyl group as a functional group, said carboxyl group being protected with an acid-decomposable protecting group, and which may further contain a halogen, oxygen or sulfur atom, R 4 is as defined for R 2 , R 5 is a C 4 -C 16 organic group which has a lactone ring as a functional group, and which may further contain a halogen, oxygen or sulfur atom, R 6 is as defined for R 2 , and X is a hydrogen atom, chlorine atom, bromine atom, or straight, branched or cyclic C 1 -C 6 alkoxy group, p is 0 or 1, q is 0 or 1, and r is 0 or 1.
