Abstract:
An apparatus for manufacturing a master by irradiation of an electron beam on a substrate mounted on a turntable, comprising:an electron-beam emitting section for emitting said electron beam; a focus control section for converging said electron beam on a principal surface of said substrate; a rotation drive section for rotating said turntable; a movement drive section for relatively moving said electron-beam emitting section and said turntable in a predetermined direction in a plane parallel to said principal surface; a first correction-signal generating section for detecting a first asynchronous component of rotational fluctuation of said turntable in said predetermined direction to generate a first correction signal; a second correction-signal generating section for detecting a second asynchronous component of rotational fluctuation of said turntable in a direction perpendicular to said predetermined direction to generate a second correction signal; and a deflection control section for performing deflection control on said electron beam on the basis of said first correction signal and said second correction signal.
