PROBLEM TO BE SOLVED: To provide an electron gun which does not cause displacement in horizontal direction of a cathode electrode. SOLUTION: The electron gun 10 has a case 11. A cathode member 31, a heating device 32, and an anode electrode 3 are arranged in the case 11. The cathode member 31 is constructed of a cathode electrode 1 and a support column 55 which supports the cathode electrode 1. The support column 55 is located at the center of a heating filament 2 1 . When vacuum treatment is performed using the electron gun 10, and the filament support column 55 is heated to increase its temperature and thermally expanded, the support column 55 makes the cathode electrode 1 move in perpendicular direction but not move in horizontal direction. Thus, electrons do not shift in horizontal direction before reaching an irradiation object in the vacuum tank from the anode electrode 3, and are precisely irradiated on the irradiation object.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing an electron emitting lithographic equipment and its electron emitting emitter for lithography using an electron emitting source of a selectively grown carbon nanotube. SOLUTION: The electron emitting lithographic equipment includes: an electron emitting source arranged within a chamber; and a stage for placing a specimen 14 spaced at a predetermined distance from the electron emitting source. The electron emitting source consists of carbon nanotubes 11 with electron emitting ability, and the carbon nanotube 11 is used as the electron emitting source in a lithography process. As a result, the lithography process, which can embody very fine line width with extremely high accuracy, becomes available. Since electron beam resists 15 and 15' in a portion, to which the electrons emitted from the carbon nanotubes 11 correspond by 1:1, are exposed, the exposed deflection, which may be produced between a center part and an end part of substrate 12, is suppressed to low. According to the present invention, such a lithography is performed with sufficient productivity. COPYRIGHT: (C)2008,JPO&INPIT
