Abstract:
1. A method for laminating a supporting substrate to a workpiece by interposition of a double-sided adhesive sheet, the method comprising: applying the double-sided adhesive sheet on the workpiece; performing position control of the workpiece and the substrate in a proximate and mutually facing condition with interposition of the laminated double-sided adhesive sheet by holding a peripheral edge of the substrate with a plurality of holding devices; laminating the substrate to the workpiece by pressing the substrate from the approximate center of a non-adhering surface of the substrate, by elastically deforming a pressing member into a flat shape to make a surface of the substrate contact to the workpiece using the pressing member made of an elastic body having an approximately hemispherical shape, and by swinging or descending edges of the plurality of holding devices with diagonal drop associated with a curvature caused by pressing of a surface of the substrate by the pressing member; and moving the holding devices outward in a radial direction of the substrate by canceling hold of the substrate by the holding device, when a pressed contact surface to the surface of the substrate by elastic deformation of the pressing member approaches the peripheral edge of the substrate.
