Abstract: An easily detachable adhesive film, which is deformed into a cylindrical shape by heating to facilitate collection, fails to be sufficiently bonded to the surface of a workpiece, if the surface of the adhesive layer is roughened by the presence of irregularities. Because of this, when water penetrates in dicing, the adhesive layer peels off from the surface of the workpiece and may fail to achieve a surface-protection purpose. In addition, when the easily detachable adhesive film is deformed into a cylindrical shape by heating, detachment stress may not uniformly applied to a workpiece, with the result that the film cannot be smoothly deformed into a cylindrical shape; at the same time, a larger amount of glue remains in the surface of a workpiece than a conventional peel-detachment.
