Electrooptic system array, charged-particle beam exposure apparatus using the same, and device manufacturing method |
摘要 |
A charged-particle beam exposure apparatus includes a charged-particle beam source for emitting a charged-particle beam, an electrooptic system array which has a plurality of electron lenses and forms a plurality of intermediate images of the charged-particle beam source by the plurality of electron lenses, and a projection electrooptic system for projecting on a substrate the plurality of intermediate images formed by the electrooptic system array. The electrooptic system array includes at least two electrodes arranged along paths of a plurality of charged-particle beams, each of the at least two electrodes having a plurality of apertures on the paths of the plurality of charged-particle beams, and a shield electrode which is interposed between the at least two electrodes and has a plurality of shields corresponding to the respective paths of the plurality of charged-particle beams.
