Abstract:
1. A method for performing electron beam duplication lithography comprising the steps of: providing a first substrate with a field emitter deposited on the first substrate in a predefined pattern whereby an active field emission material is deposited on the first substrate in the predefined pattern on a permanent basis such that all of such field emission material emits electrons on a continuous basis when activated, and whereby no active field emission material resides in spaces between the predefined pattern so that no field emission of electrons occurs in such spaces; providing a second substrate positioned a distance from the first substrate with an electron beam resist layer deposited on the second substrate; and establishing an electric field to thereby cause an emission of electron beams from the active field emission material towards the electron beam resist layer in order to modify the electron beam resist layer in a pattern substantially identical to the predefined pattern.
