Abstract:
1. An electron beam writing method for writing a pattern on a substrate applied with a resist and placed on a rotation stage having a rotary encoder by scanning an electron beam on the substrate while rotating the rotation stage, wherein, when writing a hard disk pattern constituted by a plurality of servo areas, each extending in an arc from the radial center side to outside and data areas, each between each of the servo areas, writing is started with respect to the associated radial direction position of each of the servo areas based on a predetermined encoder pulse for the associated radial direction position among those encoder pulses generated according to the rotational angle of the rotation stage that occurs after a predefined encoder pulse that occurs ahead in a rotational direction of a radial direction position whose write start position in a circumferential direction in each of the servo areas arrives first at the writing position as the rotation stage rotates and ahead of the write start position in the circumferential direction with respect to the associated radial direction position, and after a predetermined time from the predetermined encoder pulse.
