Semiconductor device manufacturing method having a step of applying a copper foil on a substrate as a part of a wiring connecting an electrode pad to a mounting terminal

摘要

A method of manufacturing a semiconductor device (10A, 10B, 10C) is provided. The method comprises a wire-forming step of forming a wiring (12A, 12B, 12C, 12D) on a substrate (40) having an electrode pad (15) so as to connect the electrode pad to a mounting terminal (14). The wire-forming step includes the steps of: applying a metal foil (25) to the substrate by providing an adhesive (18) therebetween; patterning the metal foil into a predetermined pattern so as to form the wiring; and connecting the wiring to the electrode pad electrically.
