    摘要: An alignment apparatus for mask and wafer each having alignment marks provided in a narrow strip like area between circuit patterns is disclosed, which mask and wafer are used in manufacturing semiconductor circuit elements. In the apparatus, the mask and wafer are scanned to obtain scan signals by means of which the amount of relative deviation between the alignment marks on mask and wafer is detected. By means of the detected signal, an alignment is effected between the mask and wafer in the apparatus. For this type of alignment apparatus, there is a problem that since the alignment marks are provided in the narrow strip like area, no coincidence between the scanning position and the strip area is attainable with pre-alignment accuracy. Improvement in the alignment apparatus according to the invention lies in that a reading of alignment marks is initiated after the coincidence is photoelectrically detected.

    摘要: An alignment device of a type, wherein an alignment pattern provided on a mask for fabrication of a semiconductor circuit element and an alignment pattern provided on a wafer are photoelectrically read in a dark field by a flying spot scanning system or a flying image scanning system to detect a relative positional relationship between the mask and the wafer, and a desired positional relationship is obtained by moving at least one of the mask and wafer on the basis of a detected signal. The novel feature of this alignment device resides in that the size of a line forming the alignment pattern along the scanning line is twice or more as large as the size of the scanning spot.

    摘要: In the apparatus, an image of a mask is printed on a light-sensitive layer while minimizing the debasing influences due to the diffraction occurring on the layer surface as well as due to the standing wave occurring in the layer. This apparatus includes an arrangement such that the rays coming from a light source are collimated and then directed to a fly's eye lens assembly, and the exit rays from this assembly are again collimated to illuminate the mask. The luminous fluxes of parallel rays impinging upon the mask at various angles of incidence remove the influences of diffraction on the image of the mask. Also this apparatus includes a filter removably inserted in the optical path between the light source and the assembly to remove the influence of the standing wave.
