Abstract: PURPOSE:To prevent alignment light from a wafer from being eclipsed by the side of a projection lens, etc., to enable detecting the alignment light from a wafer mark in the optimum position by causing the diffraction grating pitch of an alignment mark composed of a cross diffraction grating to differ between an alignment direction and a direction intersecting perpendicularly to that direction. CONSTITUTION:In an alignment mark composed of a cross diffraction grating to be used at the time of optically aligning two bodies, a diffraction grating pitch is caused to differ between an alignment direction and a direction intersecting perpendicularly to that direction. For example, the cross diffraction grating alternately arranging light transmission parts and light shielding parts in X- and Y-directions is used in this case. The diffraction grating pitch of the transmission part in the X-direction (alignment direction) is the same as that of the shielding part. Similarly, the pitch in the Y-direction (non-alignment direction) of the transmission part is the same as that of the shielding part and the pitch Py in the Y-direction is shorter than the pitch Px in the X- direction e.g. when the pitch Px in the X-direction is 5mum, the pitch Py in the Y-direction is 4mum.
