摘要:
To overcome the problem that a device performance is degraded by the edge roughness of a photoresist pattern, a mixture of polynuclear phenol compounds having, in one molecule, 0 to 6 functional groups which are chemically converted due to actions of an acid with the solubility in an alkaline developer reduced is used as a material for photoresist. In the mixture, two or more triphenyl methane structures are bonded to portions other than the functional group in the nonconjugated state. Furthermore, the mixture comprises polynuclear compounds with the average number of functional groups of 2.5 or below and includes the polynuclear compounds not having any functional group per molecule by 15% or less in the term of weight ratio, and the polynuclear phenol compounds having 3 or more functional groups per molecule by 40% or less.
