<P>PROBLEM TO BE SOLVED: To easily form a positioning marker on a substrate, to position the substrate with high precision, and to form the positioning marker on the substrate without the need to provide the substrate with a lug end which is not finally used. <P>SOLUTION: The substrate has the positioning marker formed with a light absorbing agent that selectively absorbs light of a specific wavelength region or with a light reflecting agent that selectively reflects light of a specific wavelength region. Preferably, the light of a specific wavelength range is near infrared light, infrared light, near ultraviolet light, or ultraviolet light. Preferably, the positioning marker is formed on a rear surface of the substrate. <P>COPYRIGHT: (C)2011,JPO&INPIT |
