An apparatus includes a beam deflection portion for deflecting the
electron beam to change an irradiation position of the electron beam; a
synchronization signal generation portion for generating a
synchronization signal which is in synchronization with the rotation of
the substrate; a controller for controlling the beam deflection portion
on the basis of the synchronization signal in order to deflect the
electron beam in a rotational radial direction of the substrate and in a
rotational tangential direction of the substrate opposite to a rotational
direction of the substrate, while drawing transition is performed from
one circle to another circle; and a beam cutoff portion for cutting off
the irradiation of the electron beam on the substrate, for a period
during the electron beam is deflected in the rotational radial direction.
