摘要： A mark detecting method and device suitably applicable to the alignment of a reticle in a semiconductor device manufacturing exposure apparatus, called a stepper, is disclosed. A mark is provided by repeated patterns having specific pitches. These patterns are set so that at least one pitch of the patterns differs, on a light-receiving surface of an image sensor which receives an image of the mark, from a multiple, by an integral number, of the sampling pitch (pitch of picture elements) of the image sensor. In one preferred form, the mark is formed by repeated patterns of a number N (.gtoreq.2), wherein at least one pitch Pp of the patterns satisfies, on the light-receiving surface of the image sensor, a relationship Pp=(m+n/N).times.Pix where m is an arbitrary number, n is an integral number which satisfies 1.ltoreq.n.ltoreq.N, and Pix is the sampling pitch of the image sensor. The image of such a mark is photoelectrically converted to thereby determine the position of the mark. With the proposed concept, any error which might be caused upon quantization of the mark image by the picture elements of the image sensor can be canceled or compensated at the time of calculation of the mark center. Therefore, the precision of the mark center detection can be improved.

摘要： A method of aligning a semiconductor wafer, usable in a step-and-repeat type exposure apparatus for projecting, in a reduced scale, images of a pattern formed on a reticle upon different shot areas on the semiconductor wafer in a predetermined sequence. According to this alignment method, the wafer is moved stepwise before the initiation of step-and-repeat exposures of the shot areas on the wafer and in accordance with a predetermined layout grid concerning the sites of the shot areas on the wafer. While moving the wafer stepwise in this manner, any positional deviation of each of some of the shot areas with respect to the layout grid is measured by use of a reduction projection lens system and, from the results of measurement, a corrected grid is prepared according to which grid the amount of stepwise movement of the wafer to be made for the step-and-repeat exposures thereof is determined. By this, for the exposures, the wafer can be moved stepwise exactly in accordance with the actual layout of the shot areas. Sample shot areas which are the subject of measurement can be selected under predetermined conditions. Additionally, of the values obtained as a result of the measurement, any extraordinary one or ones may be determined on the basis of the variance and then are excluded at the time of calculations made to determine the corrected grid. Thus, the stepwise movement of the wafer for the step-and-repeat exposures thereof can be controlled with higher precision.
