发明名称 Electron beam exposure apparatus
摘要 Disclosed is an electron beam exposure apparatus which comprises a first deflection system for deflecting an electron beam emitted from an electron gun and an objective electron lens for converging the deflected electron beam to apply the beam to a workpiece. Interposed between the objective lens and the workpiece is a second deflection system for deflecting the electron beam in parallel with the optical axis of the apparatus.
