  • Patent number: 8587130
    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.

  • Patent number: 7935574
    Abstract: The invention provides a marking method in which marking is performed on a protective film formed on a work with a high accuracy while suppressing a warpage and, also, a sheet for both protective film forming and dicing which is advantageously used in the method. The marking method comprises irradiating laser light to a laminated structure comprising a support film tensely supported by a ring frame, a protective film releasably laminated on the support film and a work fixed to the protective film, wherein the protective film is irradiated laser light from a side of the support film, to thereby mark the protective film.
