Claim 12:
13. The multifunctional lithography device according claim 8, wherein in the angular displacement mechanism, a stator of the angular displacement linear motor is fixed on an outer ring mounting plate of the crossed roller bearing, and a mover of the angular displacement linear motor is fixed on the three-point Z-direction fine displacement mechanism, the three-point Z-direction fine displacement mechanism is connected with an inner ring of the crossed roller bearing by a screw, the three-point Z-direction fine displacement mechanism is driven by the angular displacement linear motor to implement a small angle rotation with a center of the crossed roller bearing as a rotation axis, and the vacuum substrate-carrying stage mechanism may perform an XYθ displacement and a Z-direction coarse and fine displacement adjustment and leveling.
