Filed: 2000-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a charged particle beam aligner, enabling a lens to be miniaturized with little characteristic changes due to the temperature or change over aging. SOLUTION: A wafer projection lens 3 has a lens core 15, composed of a part 15a approximately enclosing a lens coil and two disc-like magnetic poles 15b vertical to an optical axis 5 at both ends thereof, so that the pole 15b projects inside a ferrite stack 16 for preventing magnetic fields generated by deflectors 9-11 from interfering with a magnetic field generated by the projection lens 3.
