发明名称 Apparatus for image transfer with charged particle beam, and deflector and mask used with such apparatus
摘要 An image transferring apparatus using a charged particle beam comprising a projection lens for transferring a pattern formed on a mask onto a target by focusing a charged particle beam passed through the mask, and a deflector for deflecting the charged particle beam passed through the mask toward a predetermined direction (x-axis direction) so that a transfer position of the pattern to the target is changed. In this apparatus, the deflector comprises a deflection coil for generating a deflection magnetic field extending in a direction (y-axis direction) perpendicular to the predetermined direction, and correction coils for generating correction magnetic fields extending in the same direction as the deflection magnetic field at areas spaced apart from the center of the deflection magnetic field along the direction (x-axis direction) perpendicular to the direction of the deflection magnetic field.
