ABSTRACT:
A charged particle beam writing method includes irradiating a shot of a charged particle beam, and deflecting the charged particle beam of the shot using a plurality of deflectors arranged on an optical path of the charged particle beam to write a pattern on a target object, wherein any one of the plurality of deflectors controls deflection of a charged particle beam of a shot different from a shot which is controlled in deflection by another deflector in the same period.
