| Zusammenfassung: | This VSB lithography system includes a first, second and third aperture for forming a single electron beam in each of the rectangular opening portion that are provided, and draws a figure pattern using the single electron beam formed by passing the beam through the first, second and third aperture in sequence. Each of the first, second and third aperture has a mechanism for rotationally driving the aperture around an optical axis up to an arbitrary angle from 0 to 360°. Further, in the third aperture, a mechanism for varying the opening slit width of the rectangular opening portion is provided. |
