Patent ID: 7141356

Claim:
An electron beam lithography method, for drawing elements that constitute a transfer pattern of a master carrier for magnetic transfer, by: placing a disk, which has resist coated thereon, on a rotatable stage, which is also movable in the radial direction thereof; rotating the rotatable stage; and scanning an electron beam emitted from an electron beam lithography apparatus; the transfer pattern comprising elements, which are formed within transfer regions of each sector of concentrically formed circumferential tracks and which have lengths in the circumferential direction that are integer multiples of a reference value; the electron beam lithography apparatus comprising: deflecting means, for deflecting the emitted electron beam in the radial direction of the disk and also in the circumferential direction substantially perpendicular to the radial direction; and blanking means for shielding irradiation of the electron beam onto portions other than drawing portions; the electron beam lithography method comprising the steps of: unidirectionally rotating the disk; repeating deflection of the electron beam in a figure 8 pattern, in which the electron beam is deflected toward the next deflection initiation point in the radial direction at track edge portions, such that the deflected directions toward the inner periphery of the disk and toward the outer periphery of the disk intersect each other; scanning the electron beam alternately toward the inner peripheral portion and the outer peripheral portion of the rotating disk at a pitch equal to the reference value; emitting the electron beam while operating the blanking means during deflection of the electron beam at the portions of the disk where the elements are drawn; and drawing the elements, which have lengths that are integer multiples of a reference value, by scanning the electron beam in the radial direction a number of times equal to the integer that the reference value is multiplied by.
