Abstract:
1. A charged particle beam exposure apparatus which splits a charged-particle beam from a charged-particle beam source into a plurality of charged-particle beams by a plurality of apertures formed in an aperture array to expose a wafer using the plurality of charged-particle beams, the apparatus comprising: a stage on which the wafer is loaded, the wafer being irradiated with the plurality of charged-particle beams which have been passed through the apertures of the aperture array; a plurality of detection electrodes which detect intensities of the plurality of charged-particle beams passing through the plurality of apertures of the aperture array to expose the wafer with the plurality of charged-particle beams, the plurality of detection electrodes being formed on the charged-particle beam source side of the light-shielding peripheral regions of the plurality of apertures of the aperture array; and a grid array which adjusts the intensities of the plurality of charged-particle beams on the basis of detection results obtained by said plurality of detection electrodes.
