Abstract:
A Blanking Aperture Array (BAA) charged-particle beam lithography system comprisinga charged-particle beam emitter source; a BAA chip having a plurality of apertures arrayed therein for shaping a charged-particle beam emitted from said emitter source so that the cross section thereof will assume a predetermined shape, and patterning an exposed sample using the charged-particle beam having passed through said apertures; and a mask having a plurality of apertures, which is arrayed to match said plurality of apertures arrayed in said BAA chip and having a size that is any multiple of the size of said apertures of said BAA chip, bored therein, wherein said mask is located on a path, along which the charged-particle beam travels, between said charged-particle beam emitter source and said BAA chip.
