ABSTRACT:
An adhesive film for semiconductor use of the present invention is used in a method in which, after the adhesive film for semiconductor use is laminated to one side of a metal sheet, the metal sheet is processed to give a wiring circuit, a semiconductor die is mounted and molded, and the adhesive film is then peeled off. The adhesive film includes a resin layer A formed on one side or both sides of a support film, the 90 degree peel strength between the resin layer A and the metal sheet prior to the processing of the metal sheet laminated with the adhesive film for semiconductor use to give the wiring circuit is 20 N/m or greater at 25° C., and the 90 degree peel strengths, after molding with a molding compound the wiring circuit laminated with the adhesive film for semiconductor use, between the resin layer A and the wiring circuit and between the resin layer A and the molding compound are both 1000 N/m or less at at least one point in the temperature range of 0° C. to 250° C.
