Abstract

In one embodiment, a multi charged particle beam writing method includes forming a multi charged particle beam with which a substrate serving as a writing target is irradiated, deflecting the multi charged particle beam to a position with a predetermined deflection offset added so that deflection voltages respectively applied to a plurality of electrodes of an electrostatic positioning deflector does not include a state where all the deflection voltages are zero, and irradiating the substrate with the multi charged particle beam. A positive common voltage is added to the deflection voltages which are applied to the respective electrodes of the electrostatic positioning deflector.
