Abstract
A control system is provided for a charged particle exposure apparatus. A plurality of dot control data are concatenated and compressed to generate compressed concatenated control data. A plurality of compressed concatenated control data are arranged to generate exposure control data. An electron beam exposure apparatus expands the exposure control data to reconstruct the plurality of dot control data, and performs exposure while controlling blankers on the basis of the reconstructed dot control data.
