摘要:
The invention relates to a process for generating a negative tone resist image comprising the steps of (1) coating a substrate with a film of a polymeric composition comprising (i) a polymer, (ii) a photosensitive acid generator, and (iii) acid labile groups; (2) imagewise exposing the film to radiation to generate free acid; and (3) developing the image with critical fluid.

A photoacid generating polymer (PAG polymer) comprises i) a first repeat unit of capable of reacting with a photogenerated acid to form a carboxylic acid containing repeat unit, ii) a second repeat unit of capable of forming the photogenerated acid, and iii) a third repeat unit comprising a norbornyl ester, wherein a norbornyl ring of the norbornyl ester comprises a monovalent substituent having the formula *-L′-C(CF3)2(OH). L′ is a divalent linking group comprising at least one carbon and the starred bond of L′ is linked to the norbornyl ring. The first repeat unit, second repeat unit, and the third repeat unit are covalently bound repeat units of the PAG polymer.

The present invention relates to a radiation sensitive photoresist composition. The composition comprises a polymer comprising at least two monomers. The first monomer has an acid cleavable tertiary ester group. The second monomer is an acidic monomer. The acid cleavable ester group of the polymer has a surprisingly low activation energy which results in improved resist images in lithographic processes.

A method of forming an image using a topcoat composition. A composition that includes functionalized polyhedral oligomeric silsesquioxanes derivatives of the formulas TmR3 where m is equal to 8, 10 or 12 and QnMnR1,R2,R3 where n is equal to 8, 10 or 12 are provided. The functional groups include aqueous base soluble moieties. Mixtures of the functionalized polyhedral oligomeric silsesquioxanes derivatives are highly suitable as a topcoat for photoresist in photolithography and immersion photolithography applications.

摘要:
A dissolution modification agent suitable for use in a photoresist composition including a polymer, a photoacid generator and casting solvent. The dissolution modification agent is insoluble in aqueous alkaline developer and inhibits dissolution of the polymer in the developer until acid is generated by the photoacid generator being exposed to actinic radiation, whereupon the dissolution modifying agent, at a suitable temperature, becomes soluble in the developer and allows the polymer to dissolve in the developer. The DMAs are glucosides, cholates, citrates and adamantanedicarboxylates protected with acid-labile ethoxyethyl, tetrahydrofuranyl, and angelicalactonyl groups.
