METHOD OF DRY ELECTRON-BEAM LITHOGRAPHY Russian patent published in 2017 - IPC H01L21/321 B81C1/00 

Abstract RU 2629135 C1

FIELD: physics.

SUBSTANCE: layer of resist is applied, which is chosen as a low-molecular-weight polystyrene, onto the substrate by the method of thermal vacuum deposition, while the temperature of the substrate during the deposition is not more than 30°C; a latent image is formed on the substrate by local exposure of a high-energy electron beam with a light dose of 2000-20000 mcC/cm2; a resist is developed, when the substrate is heated in a vacuum to the temperature of 600-800 K and at the pressure of not more than 10-1 mbar and plasma etching to transfer the pattern of the resist mask to the substrate to form the micro- and nanostructure on the substrate.

EFFECT: providing the possibility of increasing the resolution of the finished structure of nanostructure formation on surfaces of uneven complex shapes, and creating very thin resist films.
