We have demonstrated an organic solvent-free water-developable branched sugar resist
material derived from biomass for its use in green electron beam lithography. This
emphasizes the use of plant products instead of conventionally used tetramethylammonium
hydroxide and organic solvents. The rationally designed water-developable branched sugar
resist material developed in this study can be patterned with an excellent sensitivity of 7
μC/cm 2 and a resolution of 50–200 nm lines. In addition, it indicated sufficient thermal …
