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: Mark detecting method and apparatus usable, for example, in a semiconductor exposure apparatus such as a stepper for printing a pattern of a reticle upon a semiconductor wafer, for detecting, by using an image sensor, an alignment mark provided on a reticle or wafer for alignment of the same. Plural search marks are provided two-dimensionally around the alignment mark, each search mark having a first pattern and one or more second patterns indicative of the position of the alignment mark. When at least one first pattern of the search mark is caught by an image pickup device, the reticle is displaced in accordance with the positional information as indicated by the second pattern of the search mark. This brings the alignment mark within the image pickup region of the image sensor. The alignment mark is subsequenlty used to accurately align the reticle with a predetermined position. Thus, the time required for completing the reticle alignment can be reduced remarkably.
