When reduction percentage measuring method of the charged particle beam drawing device, stage phase measuring method of the charged particle beam drawing device, control manner of the charged particle beam drawing device, and
When reduction percentage measuring method of the charged particle beam drawing device, stage phase measuring method of the charged particle beam drawing device, control manner of the charged particle beam drawing device, and
A method for measuring a demagnification of a charged particle beam exposure apparatus includes measuring a first stage position of a mask stage in accordance with a mask stage coordinate system, irradiating a first charged particle beam to a first irradiation position on a specimen through the opening portion of the mask, measuring the first irradiation position in accordance with a specimen stage coordinate system, moving the mask stage to a second stage position, measuring the second stage position of the mask stage, irradiating a second charged particle beam to a second irradiation position on the specimen through the opening portion of the mask measuring the second irradiation position in accordance with the specimen stage coordinate system, and calculating a demagnification of the charged particle beam exposure apparatus from the first and second stage positions and the first and second irradiation positions.
