Abstract: A beam shape iris diaphragm and a pattern forming device using the same are provided to expose the region to form a nano pattern without overlapping the electronic beams. An electronic beam is irradiated on a substrate on which the electron-beam resist is coated for the nano pattern formation. A plate(211) is arranged on the top of substrate and an opening(215) of the square shape is formed. The length of one side of square is set up in the range of 5 to 1000um. The electronic beam in which the nano pattern information is included is irradiated on the substrate on which the electron-beam resist is coated and the nano pattern is formed on the substrate. A beam shape iris diaphragm(210) is irradiated on the substrate, and controls the shape of the electronic beam which is arranged on the top of substrate. A substrate holder(220) moves on the plane which is parallel to the plane of the beam shape iris diaphragm.

Abstract: An objective aperture and a pattern forming apparatus using the same are provided to obtain a clear atom image by reducing the background signal noise of a high resolution atom image and to form a clear pattern using the clear atom image. An objective lens aperture(700) comprises a central area(710) in which no opening is formed in order to reduce the background signal noise of a high resolution atom image, and a peripheral area(720) in which at least one opening(730) which passes diffraction beam, not transmitting beam. The central area is formed with a diameter more than 2La, where L is the distance between a specimen and the objective lens aperture and a is the convergence semiangle of electron beam irradiated to the specimen.
