The micro stage has three sets of electromagnetic driving units arranged in a horizontal plane for driving the micro stage to obtain movements within the horizontal plane with 3 degrees of freedom in X, Y and θz directions and three electromagnetic driving units arranged in a vertical direction for driving the micro stage to obtain additional movements with 3 degrees of freedom in Z, θx and θy directions. Direct driving by electromagnetic force is used in the invention, resulting in advantages over stacked structures of having a simple structure, a compact profile, a low driven weight center, low stator inertia, etc. Thus, there is no mechanical friction and damping, and high displacement resolution can be provided. The positioning error of a wafer table of a lithographic machine can be compensated, and the leveling and focusing of the lithographic machine can be achieved. The invention is also applicable in super-precise processing and sensing fields for achieving 6 degree-of-freedom motions. The micro stage, which operates on the basis of Lorentz Law, provides a linear relation between the output pushing force and the input electrical current, and thus the movement control technique for it can be well established.
