A charged-particle beam writing apparatus used for writing a predetermined pattern on a sample placed on a stage with a charged-particle beam. The apparatus comprises a height measuring unit that measures a height of the sample by irradiating the sample with light and receiving light reflected from the sample, and a control unit that receives either of height data acquired from a height data map prepared based on values measured by the height measuring unit before writing and height data measured by the height measuring unit during writing, thereby adjust an irradiation position of the charged-particle beam on the sample. |
