Abstract

A charged particle beam pattern writing apparatus in accordance with one preferred form of this invention includes an atmospheric pressure measuring unit which measures the value of an atmosphere air pressure, a coordinate value corrector which corrects three-dimensional (3D) coordinate values by use of the value of the air pressure measured, a deflection amount computing unit which calculates the deflection amount of a charged particle beam by using the 3D coordinate values corrected, an irradiator for irradiation of the charged particle beam, and a deflector for deflection of the charged particle beam based on the deflection amount.
