摘要:
The present invention provides a cross-linking agent capable of preventing formation of scum from a bottom anti-reflective coating, and also provides a composition for forming a bottom anti-reflection coating containing the agent. The cross-linking agent is a nitrogen-containing aromatic compound having at least one vinyloxy group or N-methoxymethylamide group, and the composition contains the cross-linking agent. The cross-linking agent of the formula (1) can be produced by reaction of a nitrogen-containing aromatic compound, a halogen compound having a vinyloxy group or N-methoxymethylamide group and a basic compound.
摘要:
The present invention relates to a positive bottom photoimageable antireflective coating composition which is capable of being developed in an aqueous alkaline developer, wherein the antireflective coating composition comprises a polymer comprising at least one recurring unit with a chromophore group and one recurring unit with a hydroxyl and/or a carboxyl group, a vinyl ether terminated crosslinking agent of structure (7), and optionally, a photoacid generator and/or an acid and/or a thermal acid generator, where structure (7) is wherein W is selected from (C1-C30) linear, branched or cyclic alkyl moiety, substituted or unsubstituted (C3-C40) alicyclic hydrocarbon moiety and substituted is or unsubstituted (C3-C40) cycloalkylalkylene moiety; R is selected from C1-C10 linear or branched alkylene and n≧2. The invention further relates to a process for using such a composition.
摘要:
A photosensitive positive working composition suitable for use as a photoresist, which comprises an admixture of at least one film forming resin; at least one photosensitizer; and a photoresist solvent mixture containing more than 50 weight percent of an alkylene glycol alkyl ether and less than 50 weight percent of either an alkyl alkoxy propionate or an alkyl amyl ketone, and a process for producing such a photoresist composition.
摘要:
Disclosed is an alkali-soluble, film-forming novolak resin mixture containing at least two novolak resins, each novolak resin containing the addition-condensation reaction product of at least one phenolic compound with at least one aldehyde source, wherein the phenolic compound for first novolak resin contains 90-100 mole % of meta-cresol, and the phenolic compound for the second novolak resin contains less than 50 mole % of meta-cresol. Also disclosed is a photosensitive composition, containing an admixture of: a) the above-mentioned novolak resin mixture; b) at least one o-quinone photoactive compound; and c) at least one photoresist solvent. Also disclosed is a method for producing a microelectronic device by forming an image on a substrate, which involves: a) providing the above-mentioned photosensitive composition; b) thereafter, coating a suitable substrate with the photoresist composition from step a); c) thereafter, heat treating the coated substrate until substantially all of the solvent is removed; image-wise exposing the coated substrate; and then removing the imagewise exposed or, alternatively, the unexposed areas of the coated substrate with a suitable developer.
