Abstract

This paper described a higher sensitivity non-CAR type hemicellulose resist and the effect of hemicellulose content and polymer structure for EUV lithography. Hemicellulose content and the resist structure are the keys of EUV sensitivity. The line width 14 nm L/S pattern by EUV lithography was successfully obtained. Other 2types of resist were developed for higher sensitivity of EUV lithography. The results will be reported and confirmed the effect of hemicellulose content and resist structure. Non-CAR type hemicellulose resist is one of the candidates for next generation EUV lithography resist.
