摘要:
An improved positive-working photoresist composition useful in the fine patterning work of a resist layer is proposed which is capable of giving a patterned resist layer having excellent resolution, heat resistance and orthogonality of the cross sectional profile of a line pattern with a high sensitivity to actinic rays and a wide range of the focusing depth. The photoresist composition comprises, as a uniform mixture in the form of a solution, (a) an alkali-soluble novolac resin, (b) a naphthoquinone-1,2-diazido group-containing compound as a photosensitizing ingredient and (c) a specific phenolic triphenyl methane compound substituted by cyclohexyl groups on two of the phenyl groups, such as bis(3-cyclohexyl-4-hydroxy-6-methylphenyl)-3,4-dihydroxyphenyl methane or bis(3-cyclohexyl-6-hydroxy-4-methylphenyl)-3,4-dihydroxyphenyl methane, in a specified amount.
摘要:
An improvement is proposed in a double-coated patterning plate, which consists of a substrate, an undercoat levelling layer and a photoresist layer thereon, as well as in the patterning method therewith. Different from conventional double-coated patterning plate in which the undercoat levelling layer is formed from poly(methyl methacrylate) resin, the layer in the invention is formed from a copolymeric resin of methyl methacrylate and glycidyl methacrylate in a specified copolymerization ratio and the resin is admixed with 2,2',4,4'-tetrahydroxybenzophenone. By virtue of the use of this unique resin composition for the undercoat levelling layer, the troubles due to intermixing between the undercoat levelling layer and the photoresist layer thereon can be avoided to impart the patterned resist layer with excellent properties.
