    摘要: A multi-column electron beam exposure apparatus includes: a plurality of column cells; a wafer stage including an electron-beam-property detecting unit for measuring an electron beam property; and a controller for measuring beam properties of electron beams used in all the column cells by using the electron-beam-property detecting unit, and for adjusting the electron beams of the respective column cells so that the properties of the electron beams used in the column cells may be approximately identical. The electron beam property may be any of a beam position, a beam intensity, and a beam shape of the electron beam to be emitted. The electron-beam-property detecting unit may be a chip for calibration with a reference mark formed thereon or a Faraday cup.
