| Research Abstract |
This report presents progress in the study ofa novel water-soluble green resist material derived from biomass in electron beam lithography. The approach to apply the main compounds to the plant-based raw materials in the resist material was demonstrated in the lithographic processes, in order to improve high exposure sensitivity and lower film thickness shrinkage by electron beam irradiation. The images of 100-200 nm line pattern with exposure dose of 7.0 μC/cm2were obtained using the resist layer with plant-based raw materials by specific process conditions of 75 keV electron beam lithography tool. Lower film thickness shrinkage of the developed resist material than that of the referenced acrylate type resist material was one of key to achieve the advanced lithography. The technologies using the obtained resist material and the specific process conditions of advaenced lithography are expected for environmentally-compatible nano device fabrications.
