Patent ID: 8247158

Claim:
Molecular lithographic resists having as main component a molecule combining two basic characteristics: a) the presence of at least two polycarbocyclic moieties per molecule, where at least one of them is an anthracene derivative and b) the presence of at least one acid sensitive group per molecule the general formulae of which polycarbocycle containing molecules is the following: wherein in the above formulae I, II: n or m is an integer of 1 to 4, A represents an anthracene or adamantane or steroid moiety of the following structures: X 1 , X 2 , and X 3 is a hydrogen atom, or an alkyl group or a linker selected from the group consisting of alkyl, alkoxy-moieties —COCH 2 CH 2 —, and —COCH═CH— connected directly to an acid sensitive carboxylic acid ester; X represents a linker from the group of —CH 2 —, —O—, —COO—, —COCH 2 —, —COOCH 2 — or —CH 2 CH 2 COO—CH 2 — or —CH═CH—COOCH 2 — or —OCOCH 2 CH 2 —COOCH 2 or —OCO—CH═CH—COOCH 2 — or —OCOCH 2 CH 2 — or —OCOCH═CH— or oxygenated aliphatic chain or carbocyclic aliphatic chain or carbocyclic polysubstituted aliphatic chain; S represents a central aliphatic or cycloaliphatic or aromatic polyfunctionalized core of the following structures: B is a hydrogen atom or an alkyl group or an alkoxy group or an acid sensitive alkyl carboxylic acid ester, or an additional moiety of the type A represented above, wherein if A is not an anthracene derivative in the formulae I, II, B is obligatory to be a moiety of the type A represented above containing at least one anthracene, and R 1 , R 2 can be the same or different from one another and R 1 and R 2 are chosen from a hydrogen atom or an alkyl group or a linker of —XB having X connected to a moiety of B.
