The photoresist further includes a photo acid generator that is capable of forming a strong acid. This photo acid generator may be a sulfonate ester derived from a N-hydroxyamide, or a N-hydroxyimide. Finally, the photoresist composition includes an appropriate photosensitizer.

摘要: Highly sensitive, highly absorbing deep ultraviolet and vacuum ultraviolet resists which comprise a novolak resin protected with an acid labile group and a photoinitiator which generates a strong acid upon exposure to deep ultraviolet or vacuum ultraviolet radiation. The exposed resists are reacted with organometallic compounds to form reactive ion etch resistant patterns.

摘要: Compositions suitable for forming planarizing underlayers for multilayer lithographic processes are characterized by the presence of (A) a polymer containing: (i) cyclic ether moieties, (ii) saturated polycyclic moieties, and (iii) aromatic moieties for compositions not requiring a separate crosslinker, or (B) a polymer containing: (i) saturated polycyclic moieties, and (ii) aromatic moieties for compositions requiring a separate crosslinker. The compositions provide outstanding optical, mechanical and etch selectivity properties.

摘要: Proton sponge, berberine, and cetyltrimethyl ammonium hydroxide base compounds are used as additives to chemically amplified photoresists based on modified polyhydroxystyrene (PHS). The base additives scavenge free acids from the photoresist in order to preserve the acid labile moieties on the modified PHS polymer. The base additives are well suited to industrial processing conditions, do not react with the photoacid compounds in the photoresist composition to form byproducts which would hinder photoresist performance, and extend the shelf-life of the photoresist composition. In addition, the proton sponge and berberine base additives have a different absorption spectra than the modified PHS polymer, therefore, the quantity of base additive within the photoresist can be easily assayed and controlled.

摘要: The present invention discloses particular lithographic polymeric materials and methods of using these materials, wherein the polymeric materials have acid labile or photolabile groups pendant to the polymer backbone. The polymeric materials are sufficiently transparent to deep UV radiation to permit deep UV imaging, can be used to produce resist structures having thermal stability at temperatures greater than about 160.degree. C., and are sufficiently resistant to excessive crosslinking when heated to temperatures ranging from about 160.degree. C. to about 250.degree. C. that they remain soluble in common lithographic developers and strippers.The present invention also discloses resists comprising substituted polyvinyl benzoates which, after imaging, exhibit unexpectedly high thermal stability, in terms of plastic flow. These resists cannot be imaged using deep UV because they exhibit such a high degree of opacity below 280 nm; however, they are useful as the top, imaging layer in a bilayer resist process wherein the top layer acts as a mask during deep UV exposure of the bottom layer.
