Positive photoresist composition and method of forming resist pattern
摘要:
There is provided a positive photoresist composition capable of forming a pattern with excellent resolution, excellent resistance to reflection off the substrate, and excellent perpendicularity. The positive photoresist composition comprises (A) an alkali-soluble novolak resin in which a portion of the hydrogen atoms of all the phenolic hydroxyl groups are substituted with 1,2-naphthoquinonediazidesulfonyl groups, and (B) a dissolution promoter represented by a general formula (b-1) and/or a general formula (b-11) shown below.
