    Abstract: In a charged particle beam writing method according to an embodiment, a charged particle beam is deflected by a deflector, and a pattern is written by irradiating, with the charged particle beam, a substrate having a resist film formed thereon. The method includes irradiating a pattern region, in which a pattern is to be formed, with a beam at a first dose, irradiating at least part of a non-pattern region, in which a pattern is not to be formed, with the charged particle beam at a second dose, at which the resist film is not dissolved away, and determining the second dose based on the first dose and a charge amount of the resist film corresponding to a pattern density of the pattern region, wherein a charge amount difference between the pattern region and a non-dissolution irradiation region, which is irradiated at the second dose, is smaller than that obtained when the second dose is zero.
