Abstract:
A positive photoresist composition comprising:(A) an alkali-soluble resin ingredient; and (B) a quinonediazide ester ingredient, wherein the ingredient (B) comprises: (b1) a quinonediazide ester represented by following Formula (I): wherein each of Ds is independently a hydrogen atom or a 1,2-naphthoquinonediazido-5-sulfonyl group, where at least one of Ds is a 1,2-naphthoquinonediazido-5-sulfonyl group; and (b2) a quinonediazide ester, other than the quinonediazide ester (b1), represented by following Formula (II): wherein each of R1, R2, R3, R4, R5, R6, R7, and R8 is independently a hydrogen atom, a halogen atom, an alkyl group containing 1 to 6 carbon atoms, an alkoxy group containing 1 to 6 carbon atoms, or a cycloalkyl group containing 3 to 6 carbon atoms; each of R9, R10, and R11 is independently a hydrogen atom or an alkyl group containing 1 to 6 carbon atoms; Q is a hydrogen atom or an alkyl group containing 1 to 6 carbon atoms, or Q is combined with R9 to form a cycloalkyl group containing 3 to 6 carbon members or a residue represented by following Formula (III): wherein each of R12 and R13 is independently a hydrogen atom, a halogen atom, an alkyl group containing 1 to 6 carbon atoms, an alkoxy group containing 1 to 6 carbon atoms, or a cycloalkyl group containing 3 to 6 carbon atoms; and c is an integer from 1 to 3; each of Ds is independently a hydrogen atom or a 1,2-naphthoquinonediazido-5-sulfonyl group, where at least one of Ds is a 1,2-naphthoquinonediazido-5-sulfonyl group; each of a and b is independently an integer from 1 to 3; d is an integer from 0 to 3; and n is an integer from 0 to 3, wherein, when n is 0, Q is the residue represented by Formula (III) or is combined with R9 to form a cycloalkyl group containing 3 to 6 carbon atoms.
