Positive type resist composition.

摘要

A positive type resist composition comprising an alkali-soluble resin and a quinonediazide compound, wherein the alkali-soluble resin containing resin (A) is obtainable through a condensation reaction with at least one phenol compound represented by the following general formula (I): <CHEM> wherein R1 to R3 independently of one another each represent a hydrogen atom or an alkyl or alkoxy group having 1-4 carbon atoms and k represents 1 or 2, at least one compound represented by the following general formula (II): <CHEM> wherein R4 represents a hydrogen atom, an alkyl group having 1-4 carbon atoms or a phenyl group, R5 to R7 independently of one another each represent a hydrogen atom or an alkyl or alkoxy group having 1-4 carbon atoms and n represents 1 or 2, and an aldehyde compound. This composition is excellent in the balance between performances such as sensitivity, heat resistance and profile, and is free from scum.
