    • The present invention relates, in a projection aligner wherein a mask and a wafer are held proximate to one another and wherein a circuit pattern depicted on the mask is transferred onto the wafer, to a method of detecting the respective positions of the mask and the wafer for the relative positioning between the mask and the wafer. To the end of dispensing with the withdrawal of a microscope objective in such a way that the objective of a microscope for detecting the mask and the wafer and projection light, for example, an X-ray, are prevented from interfering, thereby to achieve the enhancement of throughput and to permit the detection of the positions of the mask and the wafer even during projection, the present invention consists in that the objective of the microscope is inclined with respect to a perpendicular to the plane of the mask or the plane of the wafer being a plane to-be-detected, so as not to interfere with the projection light, for example, the X-ray, whereby the circuit pattern can be transferred while the relative positions of the mask and the wafer are being detected.

    • A method and apparatus for alignment for use in X-ray exposure or the like wherein a mask is provided having a formation of an alignment pattern made up of at least one linear segment formed in a peripheral section of the mask and a wafer is provided having a formation of an alignment pattern formed in a same direction as the alignment pattern of the mask and made up of linear segments. An illuminating arrangement illuminates a light to the mask alignment pattern along a direction inclined to the alignment direction and the mask alignment pattern and the wafer alignment pattern are imaged and transformed into a video signal. An A/D converts the video signal into a digital signal and stores the digital signal in a memory. The digital video signal is read out from the memory and averaged in a mask alignment pattern by removing a shadow portion caused by the mask alignment pattern and additionally averaged in a wafer alignment pattern area with an averaged wafer alignment pattern signal and an averaged wafer alignment pattern signal being provided. Relative displacement between the mask and the wafer is detected from the averaged mask alignment pattern signal and the averaged wafer alignment pattern signal and the mask and wafer are aligned by moving at least one of the mask and wafer so that displacement between the mask and the wafer does not exist.
