A stage control apparatus for controlling a stage on which a substrate can
be placed and moved generates a target value relating to a vertical
direction of the stage based upon substrate surface position information
that corresponds to unevenness of the surface of the substrate and
generates a drive command signal of the stage based upon a deviation
signal between the target value generated and a measured position of the
stage. A target frequency is decided upon a spatial frequency possessed
by the unevenness of the substrate surface. In order to generate the
drive command signal, use is made of a signal obtained by amplifying a
component of the target frequency of the deviation signal.
