Beschreibung
Zusammenfassung:	A charged particle beam drawing apparatus of an embodiment includes: a drawing unit to perform drawing on a workpiece on a stage by using a charged particle beam; multiple marks located on the stage and having different heights; an irradiation position detector to, when any of the marks is irradiated with the charged particle beam, detect an irradiation position of the charged particle beam on a mark surface of the mark; a drift-amount calculation unit to calculate a drift amount of the charged particle beam on the mark surface by using the irradiation position; a drift-amount processing unit to obtain a drift amount on a workpiece surface by using the drift amounts on at least two of the mark surfaces; and a drawing controller to correct an is irradiation position of the charged particle beam by using the drift amount on the workpiece surface.
