We have investigated acid-breakable (AB) resins for chemical-amplification positive resists. The AB resin was synthesized by a co-condensation reaction between an alkali-soluble polyphenol (4, 4′-[1-[4-[1-(4-Hydroxyphenyl)-1-methylethyl]phenyl]-eth

Negative electron beam resists composed of a phenylcarbinol, poly(4-hydroxystyrene) (PHS), and an onium salt have been developed to define patterns below 100-nm. Five phenylcarbinols were evaluated as a precursor of a dissolution inhibitor (PDI) and

Chemically amplified negative resists made by utilizing the polarity-change reaction of phenylcarbinol were investigated for electron beam lithography. The resist composed of 1, 3-bis(α-hydroxyisopropyl)benzene (Diol-1), m/p-cresol novolak resin, an

Chemical amplification positive resists using tetrahydropyranyl-protected polyvinylphenol (THP-M) were investigated for electron-beam lithography. To enhance the resist performance, we used a new novolak resin and trimethylsulfonium triflate (MES) as

Demethoxycarbonylation of methyl 2,5,-di-tert-butyl-1H-azepine-1-carboxylate using 1,8-diazabicyclo[5.4.0]undec-7-ene gives exclusively two isomers of 3H-azepine derivatives, while methyl 3,6-di-tert-butyl-1H-azepine-1-carboxylate gives a mixture of

Demethoxycarbonylation of methyl 2,5-di-tert-butyl-1H-azepine-1-carboxylate using 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) gave 3H-azepines. Under similar conditions, methyl 3,6-di-tert-butyl-1H-azepine-1-carboxylate gave not only the 3H-azepine but

A new ring contraction reaction giving pyridine derivatives from 3,6- and 2,5-di-tert-butyl-3H-azepines was observed by a successive treatment with bromine and aqueous K2CO3. A plausible mechanism via azatropilium cation for the rearrangement was dis

An acid-catalyzed etherification of carbinol has been used in the design of an alkali developable, highly sensitive negative resist. The resist consists of diphenylcarbinol (DPC), an acid generator, and a novolak resin shows the best lithographic per

We have designed a new chemical amplification (CA) positive resist for 0.1micrometers reticle fabrication. This positive resist consists of an acid-generator, an acid-diffusion controller, and an acid-breakable (AB) resin that can be converted to ini
