Method of aligning substrates

The invention of claim 1 as a substrate alignment method for aligning a substrate and a second substrate, (a) a first image display device and a second image, each representative of the first alignment side information and the second alignment assistance information fixedly on the display device step; (B) wherein the first image and the second image acquired a the first substrate by recording the relative position via the first image capture device and a second image capture device is determined with respect to each other with respect to the vertical and horizontal directions, each of the first an image display device, and displaying on the second image display device; (C) the step of moving the first substrate a pattern image of the first substrate obtained from the first image and the second image is to be matched to said first alignment side information and the second alignment side information and fixed; (D) the step of fixedly displaying the first image display device and each of the third and fourth alignment auxiliary information auxiliary information sorted in the second image display device; (E) perpendicular to the second substrate to the first to move to a first substrate, with respect to the vertical and horizontal directions, and the relative positioning with respect to each other, each of the first image capture device and said second image capture device the position is fixed a third image capture device and the fourth obtained by recording the second substrate through the image capture device of claim 3, respectively the image and the fourth image on the first image display device and the second image display device displaying; And (f) to the third image and the fourth one is arranged above the third pattern image of the second substrate obtained from a video auxiliary information and the first substrate to the second substrate so that the matching in said fourth alignment assistance information the substrate alignment method is provided that includes; aligning the relative movement with respect. In accordance with the present invention align the substrate using the alignment pattern and the auxiliary information to be displayed on the screen formed on the substrate, and may also provide a substrate alignment method that can be bonded to the aligned substrate. In particular, even if the transparency of the substrate is very low and not able to determine the alignment marks or reference marks align the substrate, unlike the conventional substrate alignment method and may also be bonded to the aligned substrate. It may also be omitted, while the process for forming an alignment mark or the reference mark on the substrate align the substrate and also bonding the aligned substrates, it is possible to reduce the manufacturing cost and manufacturing time of the product.
