Patent ID: 8021964

Claim:
A method of producing segmented chips by grinding a back surface of a material to be ground which includes a plurality of chips segmented into individual chips by at least partly cutting the chips in the direction of thickness thereof along the boundaries of the chips; wherein gaps among the individual chips formed by cutting are filled with a liquid adhesive, said material to be ground is laminated, with its back surface exposed, on a rigid support material, and said adhesive is cured or solidified to form a laminate of the material to be ground having the plurality of chips; said laminate is ground from the back surface side of said material to be ground thereby to obtain thin and individually separated chips on the laminate; said rigid support member is removed from said laminate; a flexible adhesive sheet is adhered onto the adhesive solid material of the laminate from which said rigid support material has been removed; and the individual chips held by the adhesive solid material on said flexible adhesive sheet are picked up and recovered, including a transfer step in which after the grinding, said laminate is adhered onto a first flexible adhesive sheet so as to come in contact with the back surfaces of said chips, said rigid support material is removed from said laminate, a second flexible adhesive sheet is adhered to the adhesive solid material of the laminate from which said rigid support material has been removed, and said first flexible adhesive sheet is removed.
