Patent ID: 7205557

Claim:
A variable rectangle-type electron beam exposing apparatus for forming rectangular beams of different angle comprising: a first slit member in which a plurality of rectangular apertures are respectively arranged by different angles; a second slit member in which a plurality of rectangular apertures, which are respectively positioned in parallel with the corresponding rectangular apertures of the first slit member, are arranged; and a deflecting unit for deflecting an electron beam, which has been transmitted through a plurality of apertures of the first slit member, so that, when the electron beam transmitted through the first aperture of the first slit member passes through the corresponding first aperture of the second slit member, the electron beam transmitted through the apertures other than the first aperture of the first slit member can be intercepted by the second slit member, and, when the electron beam transmitted through the second aperture of the first slit passes through the corresponding second aperture of the second slit member, the electron beam transmitted through the other apertures than the second aperture of the first slit member can be intercepted by the second slit member.
