Abstract:
A device for electron-beam lithography for manufacturing a master disk, the device comprising:means for moving the master disk, means for generating a row of electron beams, and means for directing electrons from said row of beams onto a track on the master disk, wherein the row of beams extends substantially parallel to the track,an aperture element comprising at least one aperture, first lens means disposed between the means for generating said row of beams and the aperture element for the purpose of deflecting electrons in said row of beams in the direction of said at least one aperture, second lens means disposed between the aperture element and the master disk for deflecting electrons that have passed through said at least one aperture in an intended direction onto the master disk, and controllable means for independently deflecting electrons in said row of beams to a position substantially beside the aperture are disposed between the means for generating said row of beams and said aperture element.
