To enable high acceleration and high moving speed of a pattern support or
a substrate table of a lithographic apparatus, one of the pattern support
and the substrate table is supported by an actuator for relatively large
displacements, whereas an actuator for accurately positioning is omitted.
The other one of the pattern support and the substrate table is supported
by an actuator assembly including an actuator for accurate positioning
and an actuator for relatively large displacements. An alignment accuracy
of a patterning device and a substrate is achieved by providing a control
system that is adapted to position the other one of the pattern support
and the substrate table such that a positioning error of the one of the
pattern support and the substrate table is compensated by the positioning
of the other one.
