Abstract

PURPOSE:To obtain the satisfactory alignment accuracy between a mask and a wafer by a method wherein a vacuum chuck is controlled in accordance with measured signals from a first vacuum sensor and a second vacuum sensor and the mask is transferred between a mask holder and a wafer-mask stage. CONSTITUTION:When a mask 8 is transferred between a mask holder 10 and a mask stage 4, a position of the mask 8 is detected by a change in a degree of vacuum which is measured by using vacuum sensors M1, M2; opening and closing valves 5, 11 are operated by a control device 13; a vacuum chuck is controlled. A wafer 2 and the mask 8 fixed on a wafer-mask stage 1 are trans ferred collectively to an exposure position; an exposure operation is executed. Accordingly, a relative positional relationship between the mask 8 and the wafer 2 is definite; a satisfactory alignment operation can be executed.
