Exposure apparatus, control method thereof, and device manufacturing method |
摘要 |
This invention provides a multi-charged-particle beam exposure apparatus capable of easily correcting at a high precision the electron-optic characteristics of each column which constitutes an electron-optic system. The exposure apparatus has magnetic lens arrays (ML1, ML2, ML3, and ML4) which commonly adjust the electron-optic characteristics of a plurality of columns which constitute the electron-optic system, and dynamic focus lenses or deflector arrays which individually correct the electron-optic characteristics of the columns.
