Abstract: Exemplary embodiments of the invention disclose an exposure apparatus and a method of tuning parameters of a chuck, which may reduce a time taken to level the chuck by previously tuning parameters of the chuck. The method of tuning parameters of a chuck includes detecting a tilt component of the chuck, performing chuck tilt adjustment to minimize the tilt component of the chuck, and tuning the parameters of the chuck if a residual tilt component is present after performing the chuck tilt adjustment.
