Even if the distance between them is slightly narrowed, the slight error in the Z direction can be corrected and maintained at the predetermined distance. As a result, the substrates A and B can be adjusted to an optimum interval for positioning with a simple structure without increasing the number of components penetrating through the vacuum chamber S.
