Abstract
A die-sorting sheet includes a pressure-sensitive adhesive layer exposed on an outer periphery of the carrier sheet, and a base film exposed on a central area that is inside the outer periphery. A method for transporting a chip having an adhesive layer includes the steps of: providing the above die-sorting sheet that is fixed with a frame through the pressure-sensitive adhesive layer on the outer periphery; temporarily attaching a picked up chip through an adhesive layer thereof onto the base film exposed on the die-sorting sheet; and transporting the die-sorting sheet to a subsequent step while the chip is temporarily attached on the sheet through the adhesive layer.
