摘要

The present invention provides a non-transitory medium storing a program for correcting an irradiation position of a charged particle beam, a correction amount calculation device, a charged particle beam irradiation system, and a method for correcting an irradiation position of a charged particle beam. The medium includes instructions for causing a control unit to perform actions including replacing charging of a resist with surface charges at an interface between the resist and a work piece, and calculating a charge density distribution of the surface charges; calculating a trajectory of a charged particle based on the charge density distribution; calculating an amount of error of the irradiation position of the charged particle beam based on the trajectory and calculating an amount of correction of the irradiation position of the charged particle beam based on the error amount.
