Patent ID: 7326510

Claim:
A resist composition characterized in that it comprises a polycyclic compound having one of the general formulae I, II, III, IV and V, wherein: n and m are integers of 1 to 5, F is selected from a hydrogen atom, —OH, —NH, —COOH, alkyl or alkoxy; X represents a linker selected from —CH 2 —, —O—, —CH 2 NH—, —CH 2 O—, —CO—, NH—, —CONH—, —COO—, ALKYL, —OCOO—, —OCONH—, an oxygenated aliphatic chain, a carbonylated aliphatic chain, a carbocyclic, polysubstituted aliphatic chain and a carbocyclic with functional groups F; and A represents an anthracene or adamantane or steroid moiety of the following structures: wherein: R 1 represents a hydrogen atom or alkyl or alkoxy or —(CH 2 ) v —NHCO—R 4 in which v is an integer of 0 to 5 and R 4 a hydrogen atom, alkyl or alkoxy; R 2 represents a linker selected from —CH 2 —, —O—, —CH 2 NH—, —CH 2 O—, —CO—, —NH—, —CONH—, —COO—, alkyl, —OCOO—, —OCONH— and it is not connected to R 1 by any chain; R 3 is a functional group or a hydrogen atom; X 1 to X 7 may be the same as or different from one another and each thereof represents a hydrogen atom, an alkyl group, a halogen or a nitro group; and R represents a hydrogen atom, an alkyl group or an additional moiety of the type A, F or X defined above to provide a polycyclic compound having at least two A groups.
