Abstract:
1. A manufacturing device of a roller mold which is a roller-like die to transfer a pattern, comprising: an electron beam irradiation device which irradiates, with electron beams, the roller mold coated with a resist; a mask which has an opening that allows passage of some of electron beams emitted from the electron beam irradiation device, and which forms a plurality of beams that perform simultaneous depiction on the resist; a rotation drive device which rotates the roller mold around a rotary shaft; a displacement amount detection sensor which detects a rotational runout displacement amount of the roller mold in the direction of the rotary shaft at the rotation by the rotation drive device; a control device which receives a detection signal from the displacement amount detection sensor, and transmits a control signal to allow a depiction position on the resist of the roller mold by the electron beams to follow the roller mold; and an actuator which, based on the control signal from the control device, allows the depiction position by the electron beams to follow the displacement of the roller mold in the direction of the rotary shaft, wherein misalignment of an exposed position of the resist, which is caused by rotational runout displacement of the roller mold in the direction of the rotary shaft, is suppressed.
