Method for manufacturing an electrostatic deflector

摘要

The present invention relates to a charged particle beam exposure apparatus, deflecting a charged particle beam formed into a predetermined shape by being passed through a predetermined transmission mask, and irradiating a predetermined location on the surface of a sample with the charged particle beam. The apparatus comprises: a mirror barrel through which the charged particle beam is passed; and an electrostatic deflector, provided in the mirror barrel, for deflecting the charged particle beam. The electrostatic deflector has a plurality of pairs of electrodes, which are made of a conductive material having carbon as a primary element and are embedded in an internal face of an insulating cylinder. The present invention also relates to a method for forming the electrostatic deflector.
