ADHESIVE FILM FOR SEMICONDUCTOR USE, METAL SHEET LAMINATED WITH ADHESIVE FILM, WIRING CIRCUIT LAMINATED WITH ADHESIVE FILM, AND SEMICONDUCTOR DEVICE USING SAME, AND METHOD FOR PRODUCING SEMICONDUCTOR DEVICE

摘要

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 least one point in the temperature range of 0° C. to 250° C.
