Charged-particle beam exposure apparatus, exposure system, control method therefor, and device manufacturing method

摘要

An element exposure field (EF) having a size falling within a range where aberration by an electron optical system is suppressed to a predetermined amount or less is divided into a plurality of partial fields (PF), and a pattern is drawn on a substrate with an electron beam on the basis of exposure information in which charged-particle beam dosages for the plurality of partial fields are set. Each partial field (PF) is continuously scanned and exposed with a corresponding dosage contained in the exposure information. Scan/exposure for each partial field (PF) is sequentially executed for all the partial fields (PF) in the element exposure field (EF).
