摘要:
An electron beam exposure apparatus for exposing wafer with an electron beam, includes: a first electromagnetic lens system for making the electron beam incident substantially perpendicularly on a first plane be incident on a second plane substantially perpendicularly; a second electromagnetic lens system for making the electron beam that was substantially perpendicularly incident on the second plane be incident on the wafer substantially perpendicularly; a rotation correction lens provided within the first electromagnetic lens system for correcting rotation of the electron beam caused by at least the first electromagnetic lens system; a deflection system for deflecting the electron beam to a position on the wafer; and a deflection-correction optical system provided within the second electromagnetic lens system for correcting deflection aberration caused by the deflection system.
