Abstract

Complex and fine patterns may be formed by an exposure apparatus that decreases movement error of a stage including a beam generating section that generates a charged particle beam, a stage section that has a sample mounted thereon and moves the sample relative to the beam generating section, a detecting section that detects a position of the stage section, a predicting section that generates a predicted drive amount obtained by predicting a drive amount of the stage section based on a detected position of the stage section, and an irradiation control section that performs irradiation control for irradiating the sample with the charged particle beam, based on the predicted drive amount.
