PROBLEM TO BE SOLVED: To easily separate a brittle material bonded on a hard plate and avoid cracks or damages on the same upon separation. SOLUTION: The brittle material 10 is bonded onto the hard plate 11 through an adhesive double coated sheet 12, equipped with adhesive agent layers 15, 15' on both surfaces of the same, to form a unit U. Thereafter, the unit U is dipped in a liquid L, in which an adhesive agent is insoluble or hardly dissolved, to impregnate the liquid L into an interface between the adhesive double coated sheet 12 and the brittle material 10 or impregnate the liquid L into an interface between the adhesive double coated sheet 12 and the hard plate 11. Thereafter, the brittle material 10 is separated from the end part of the unit U. COPYRIGHT: (C)2004,JPO |
