Abstract
Disclosed is an electron beam lithography method. The method comprises obtaining a target pattern having a first width to be formed on a substrate, acquiring a dose pattern including a fixed dose cell which corresponds to a region of the dose pattern with a constant dose amount of electron beam to be provided onto the substrate and a variable dose cell which corresponds to a region of the dose pattern with a variable dose amount which is varied based on the first width of the target pattern, and providing the electron beam to expose the substrate according to the dose pattern.
