    • PROBLEM TO BE SOLVED: To draw a servo pattern and a groove pattern in a fine pattern of a discrete track media with a given dose at a high speed with high accuracy. SOLUTION: A fine pattern including a servo pattern 12 comprising servo elements 13 and a groove pattern 15 separating adjacent data tracks in a groove state, is drawn by scanning an electron beam EB on a substrate 10 coated with a resist 11. The drawing process includes: drawing the servo pattern 12 by scanning the electron beam to fill servo elements 13 of a plurality of tracks each by each by deflected in X-Y directions and reciprocal oscillation in a radial direction, while the substrate is rotated in one direction; followed by configuring the groove pattern 15 as an arrangement of a plurality of groove elements 16 prepared by dividing the pattern at a predetermined angle, and drawing the groove pattern 15 by greatly deflecting the electron beam in a circumference direction so as to sequentially scan the groove elements 16 of a plurality of tracks. Thus, a plurality of tracks are drawn in a single rotation of the substrate. COPYRIGHT: (C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an electron beam drawing apparatus capable of compensating the deviation of a drawing position by an electron beam caused by a mechanical error, misalignment of an optical axis, optical distortion or the like, and performing a highly precise drawing. SOLUTION: In the electron beam drawing apparatus, an output signal from a deflection amplifier 46Y and a signal, corresponding to an angle deviation from a deflection amplifier 46X, are outputted to change the deflection direction of an electron beam (to rotate), in order to compensate for the angle deviation between a linear movement direction of the rotation stage and the deflection direction of an actual electron beam, when the electron beam is deflected by a first command signal DO(Y) from a first commanding device 42 that deflects the electron beam. An electron beam is made to scan so as to produce a solid image of an element constituting a desired pattern. A second command signal MO(X), MO(Y) from the first commanding device 42 is converted into a second command signal MO(X)', MO(Y)' by a conversion table of a compensation circuit 52 and makes the commanded position of the electron beam coincide with the actual scanning position.
