A charged particle beam exposure method for shaping a charged particle beam by using an aperture mask having character apertures corresponding to the character shapes extracted from a semiconductor device pattern, the method comprises arranging the character apertures in the aperture mask, each of the character apertures having a shape corresponding to character shapes extracted from a standard cell pattern used for designing a semiconductor device, and varying the shape of the charged particle beam according to the outer shape of each of the character apertures, thereby applying the shaped charged particle beam to the character apertures.
