Abstract: PURPOSE: To align substrates by externally moving substrates in XYθ directions outside of pressurizing plates while keeping only the space between the pressurizing plates in a sealed state. CONSTITUTION: The pressurizing plates 1, 2 holding two substrates A, B are moved nearer to each other so as to seal the space between the peripheral edges 1a, 2a of the plates by a movable sealing means 4 to form a section of a closed space S while the substrates A, B are moved nearer to each other to form a specified gap. Then while the air in the closed space S is evacuated, the pressurizing plates 1, 2 are relatively moved and adjusted in along XYθ directions to roughly align the substrates A, B. After a specified vacuum degree is obtained, the movable sealing means 4 is deformed to move the substrates A, B further nearer to each other the position where the gap between the substrates A, B is sealed with an annular adhesive C. In this state, the pressurizing plates 1, 2 are relatively moved and adjusted in the XYθ directions to finely align the substrates. Then the substrates are released from only one of the plates 1, 2 to return the closed space S to the atmospheric pressure so that the gap is uniformly pressed by the pressure difference between the inside and outside of the substrates A, B to form a specified gap.
