Abstract:
1. An attaching method for attaching a supporting plate to a surface of a substrate with an adhesive, comprising the steps of: applying an adhesive to the surface of the substrate; heating and thereafter cooling the substrate; positioning a center of the substrate and the center of the supporting plate to coincide with each other; and forming a layered structure by pushing the supporting plate onto the substrate in a pressure-reduced atmosphere: wherein the positioning step involves use of a pair of alignment members arranged to freely move back and forth in a horizontal direction, and blades for supporting a lower surface of a periphery of the supporting plate and pushing members for performing positioning in a state where the supporting plate is superposed on the substrate are provided at tip ends of the alignment members, wherein each of said pushing members includes a pair of rollers, a thickness of the rollers is larger than a combined thickness of the substrate and the adhesive, and the supporting plate is supported only by the blades before the supporting plate is adhesively bonded to the substrate.
