The invention provides an active-balance-mass-based dynamic-magnetic-steel magnetic levitation dual-stage vector arc switching method and device and belongs to the technical field of semiconductor manufacture equipment. The active-balance-mass-based dynamic-magnetic-steel magnetic levitation dual-stage vector arc switching device comprises a support framework, a balancing mass block, magnetic levitation stages, a stage measurement device and a stage driving device, wherein the two stages work between a measurement site and an exposure site; the positions of the stages are measured by plane gratings; an active compensation structure consisting of dual-motor crank and rocker mechanisms is adopted for motion compensation for the balancing mass block; the stages are driven by a dynamic-magnetic-steel magnetic levitation planar motor; in the switching process of the two stages, the planar motor drives the two stages to achieve quick single-beat arc switching. The invention solves the problem that a conventional switching scheme is more in beat, long in track, more in start and stop process, long in stabilizing time and the like, the switching processes are reduced, the switching time is shortened, and the productivity of a lithography machine is improved.
