An exposure apparatus which draws a pattern on a substrate with electron
beams. The apparatus includes a substrate stage which supports the
substrate, a transfer stage which moves the substrate stage, an
electromagnetic actuator which moves the substrate stage relative to the
transfer stage, a first measurement system which measures a position of
the transfer stage, a second measurement system which measures a position
of the substrate stage, a controller which controls the electromagnetic
actuator on the basis of measurement results obtained by the first and
second measurement systems, a deflector which deflects electron beams
with which the substrate is irradiated, and a filter which performs
filtering for a measurement result obtained by the second measurement
system and supplies the filtered measurement result to the deflector.
