Structure and steps are provided for detecting the position of a surface of the object in a direction perpendicular to the surface of the object. Structure and steps are also provided for determining the position of a predetermined plane parallel to the surface of the object based on the detected position of the object surface. Structure and steps are also provided for detecting the positions of the marks within the predetermined plane.
