Title: Charged-beam exposure device
Inventor: OGASAWARA MUNEHIRO
IPC: H01J37/305
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain the full amount of deflection of a charged beam by a deflection amplifying means even if the amount of deflection of the charged beam, which is deflected by a deflecting means single-handedly, is a small quantity by a method wherein the amount of deflection of the charged beam deflected by the deflecting means is amplified by the deflection amplifying means. SOLUTION: An electron beam 5 deflected by a deflector 1 is further deflected by the work of a lens 2 so as to pass through the front focal position 6 of a lens 3 and thereafter, the orbital of this deflected electron beam 5 is curved by the work of the lens 3 and a mask 4 is emitted almost vertically with the beam 5. Thereby, when the deflector 1 is assumed an electrostatic deflector, for example, the voltage, which is required for obtaining by this electrostatic deflector the same amount of deflection as that of deflection of the electron beam which is obtained by a conventional deflector, is obtained by only the amount of a voltage of a level of about half of the conventional voltage level. As a result, it becomes unnecessary to feed a high- level and high-frequency voltage to an electrode with good accuracy.  Accordingly, an electron-beam exposure device, which extends easily the scanning region of the beam 5 and has a throughput higher than that of a conventional electron-beam exposure device, can be realized.
