ABSTRACT:
A lithography system and method for operating the same. The lithography system may include a cathode adapted to emit an electron beam, a beam-homogenizing structure, capable of increasing at least one of the uniformity and energetic of the electron beam, and a mask adapted to accelerate the electron beam to form a pattern on a wafer.
