Abstract: PURPOSE:To control a bonding power of a chip arbitrarily and accurately and to prevent the chip from being cracked by a method wherein a recessed part or a protruding part is formed on the surface of an adhesive material. CONSTITUTION:Recessed parts are formed, in a grid shape, on the surface of an adhesive material 2 with which the whole surface of a base material 5 of an adhesive tape for dicing has been coated; a depth of the recessed parts is 2 to 10mum; a recessed-part width is 0.5 to 2mm; a pitch between the recessed parts is 1 to 5mm; when these sizes are changed, a contact area of a chip to the adhesive material 2 can be changed arbitrarily. Inversely, protruding parts can be formed in a grid shape. When the recessed parts or the protruding parts are formed on the adhesive material, the recessed parts or the protruding parts are formed in advance, by using a metal mold, on a releasing paper used to protect the surface of the adhesive material; after that, the releasing paper is pressed and bonded to the adhesive material. Thereby, a recessed shape or a protruding shape can be formed easily on the surface of the adhesive material 2. Thereby, a bonding power of the chip can be controlled arbitrarily and accurately; it is possible to prevent the chip from being cracked.
