CPC classification number: G03F7/039

Abstract: Resists for use in ultraviolet, electron beam and x-ray exposure devices comprising a polymeric or molecular composition the solubility of which is dependent upon the presence of acid removable protecting groups and a sulfonic acid precursor which generates a strong acid upon exposure to such radiation. The preferred sulfonic acid precursors are triflate esters or benzenesulfonyloxy esters of N-hydroxyimides.

Abstract: A co-polymer of benzophenone and bisphenol A has been shown to have DUV absorption properties. Therefore, the co-polymer has particular utility as an antireflective coating in microlithography applications. Incorporating anthracene into the co-polymer backbone enhances absorption at 248 nm. The endcapper used for the co-polymer can vary widely depending on the needs of the user and can be selected to promote adhesion, stability, and absorption of different wavelengths.
