Abstract:
An apparatus for forming a pattern for a semiconductor device, comprising:beam shaping means for shaping, to a predetermined shape, one of a charged particle beam and an electromagnetic beam; positioning means for positioning the position of the beam of the predetermined shape in a single unit region of a substrate with a photosensitive film formed thereon, sequentially forwarding the position in which the beam is to be radiated, butt-joining the single unit region to another single unit region to form a plurality of butt-joined unit regions, and situating butting portions of the butt-joined unit regions constituting the desired exposed region, in a first area of a layer to be formed other than a second area of the layer in which predetermined characteristics of a function of the semiconductor device are determined by a pattern width of the exposed region in association with another pattern formed in another layer; and shot exposure means for radiating the single unit region with the beam for a predetermined period of time and for repeating shot exposure in units of a single unit region to thereby form a desired exposed region.
