Abstract:
1. A resist composition comprising: a photosensitive polymer polymerized with (a) at least one of the monomers having the respective formulae:  where R1 and R2 are independently a hydrogen atom, alkyl, hydroxyalkyl, alkyloxy, carbonyl or ester, and x and y are independently integers from 2 to 6, and (b) a (meth)acrylate monomer; and a photoacid generator (PAG); wherein the formula of the photosensitive polymer is one selected from the formulae:  where R3 is a hydrogen atom or methyl, R4 is an acid-liable group, m/(m+p) is in the range of 0.01-0.5,  where R3 is a hydrogen atom or methyl, R4 is an acid-liable group, n/(n+p) is in the range of 0.01-0.5, and  where R3 is a hydrogen atom or methyl, R4 is an acid-liable group, (m+n)/(m+n+p) is in the range of 0.01-0.5.
