Patent ID: 7659142

Claim:
A method of manufacturing a semiconductor device, the method comprising: providing a semiconductor chip on which an electrode and a passivation film is formed; forming a metal film on the passivation film; forming a resin layer such that the resin layer has a first portion, a second portion and a first hole, the first portion being formed on the passivation film, the second portion being formed on a first part of the metal film, the first hole being disposed on a second part of the metal film; forming a conductive foil electrically connected to the electrode above the first hole such that the first hole being interposed between the second part of the metal film and the conductive foil and a first part of the conductive foil being disposed above the second part of the metal film; and forming an external electrode on the first part of the conductive foil such that the external electrode is positioned above the first hole.
