Supercritical carbon dioxide (scCO2) solubility characteristics of various polyphenols and their derivatives were investigated for the sake of resist materials for scCO2 development. Some 3 nuclei-polyphenols were fairly soluble in scCO2 at the condi

A positive chemical amplification resist based on acid-catalyzed fragmentation of the acetal groups in the polymer main-chain has been developed for electron-beam (EB) nanolithography. This resist consists of an acid generator, an acid-diffusion cont

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

The effect of m/p-cresol novolak molecular-weight-distribution (MWD) and dissolution inhibitor structure on resist performance were investigated. A novolak resin richer in p-cresol ratio gave a large dissolution inhibition capability of polymeric dis

A single-layer resist process using a high resistivity positive resist by solubility reversal (PSR) for electron beam direct writing is described. Conventional PSR designed for mask creation is found to have inhomogeneous dissolution characteristics

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

The technologies for future lithography have been proposed, such as i-line phase-shifting lithography, deep-UV lithography and electron beam lithography. We have proposed several types of chemical amplification resist systems for future lithography.
