Patent ID: 7807988

Claim:
An electron beam lithography apparatus for drawing a desired pattern by irradiating resist applied to a substrate with an electron beam, comprising: a rotating stage which supports the substrate; a stage driving device which moves the rotating stage linearly in one direction only; a first command device which outputs a first command signal for deflecting the electron beam in a linear movement direction of the rotating stage; a signal processing device which processes the first command signal output from the first command device based on an angle between the linear movement direction of the rotating stage driven by the stage driving device and a deflection direction of the electron beam deflected by the first command signal from the first command device so that the deflection direction of the electron beam aligns with the linear movement direction of the rotating stage; a second command device which outputs a second command signal for causing the electron beam to draw an element included in a predetermined pattern which is set with reference to the linear movement direction of the rotating stage driven by the stage driving device and a moving position of the electron beam deflected based on the first command signal; and a deflecting device which deflects the electron beam based on a command signal which added up the first command signal processed by the signal processing device and the second command signal output from the second command device.
