Abstract:
A charged-particle beam exposure apparatus for exposing a surface to be exposed by using a plurality of charged-particle beams, comprising:a charged-particle source for emitting a charged-particle beam; a substrate having a plurality of apertures; an irradiation electrooptic system for irradiating said substrate with the charged-particle beam emitted by said charged-particle source; element electrooptic systems for forming a plurality of intermediate images of said charged-particle source by forming the intermediate images of said charged-particle source by charged-particle beams having passed through the apertures of said substrate; a projection electrooptic system for projecting the plurality of intermediate images on the surface to be exposed; and adjustment means for adjusting incident angles of the charged-particle beams incident on said element electrooptic systems in order to adjust positions where the plurality of intermediate images are projected on the surface to be exposed.
