Abstract:
A lithography method comprising the steps of:preparing a lithography system havinga charged particle beam generation section for generating a charged particle beam,a mask stage for holding a transfer mask to which the charged particle beam is applied, anda wafer stage for holding a wafer to be processed so as to face the charged particle beam generation section via the transfer mask;setting the transfer mask on the mask stage;setting the wafer coated with a photoresist on the wafer stage;providing a fluorescent film between the transfer mask and the wafer coated with the photoresist;irradiating the fluorescent film with the charged particle beam which passes through an opening portion of the transfer mask; andapplying a light onto the photoresist film formed on the wafer by a light emitted from the fluorescent film.
