ABSTRACT:
The stage construction of the present invention includes a fixed stage and a magnetically levitated movable stage which is driven in mutually perpendicular X, Y, and Z axis directions with respect to the fixed stage by magnetic action between itself and the fixed stage. The fixed stage includes a magnet and a closed plenum in which the magnet is sealed. The movable stage includes a magnetic material which is opposed to the magnet and which experiences an attractive or repulsive magnetic force with respect to the magnet.
