Claim 10:
11. The multifunctional lithography device according claim 8, wherein the substrate-carrying stage motion system comprises the XY-direction macro-motion system and the Z-direction macro-micro three-point leveling system, and completes an XY-direction displacement using a construction of the first linear actuator and the second linear actuator with the first linear guide rail and the second linear guide rail, the coarse displacement closed-loop system is placed on a grinding surface of the upper surface of the XY-direction macro-motion system, and implements a coarse leveling of the substrate-carrying stage using a three-point design solution, the coarse displacement closed-loop system and the angular displacement mechanism enable the three-point Z-direction fine displacement mechanism to have a great micro adjustment performance, and the vacuum substrate-carrying stage mechanism 12 is arranged on a topmost layer and integrates a summation of all motions to achieve a four-axis macro-micro-leveling and alignment function.
