Abstract:
1. A charged particle beam exposure apparatus which exposes a substrate using a charged particle beam, comprising: first formation means for forming an image of a charged particle source which emits a charged particle beam; second formation means, which has an aperture array with a plurality of apertures, for forming a plurality of images of the charged particle source from the image of the charged particle source through the aperture array; a reduction electron optical system which reduces and projects the plurality of images of the charged particle source onto the substrate; and first astigmatism generation means, which is arranged between the charged particle source and the aperture array of the second formation means, for generating astigmatism when said first formation means forms the image of the charged particle source in order to correct astigmatism generated in said reduction electron optical system.
