Patent ID: 7964493

Claim:
A method of manufacturing a semiconductor device including a semiconductor substrate, a plurality of semiconductor chips formed on the semiconductor substrate, the semiconductor chips each having an electrode pad, an internal connecting terminal provided on the electrode pad, and a wiring pattern which is electrically connected to the internal connecting terminal, comprising: a resin layer forming step of forming a resin layer having a thickness that is larger than a height of the internal connecting terminal so as to cover the semiconductor chips at a side on which the internal connecting terminal is provided, said resin also covering a side surface of the internal connecting terminal, and an upper surface of the internal connecting terminal; a metal layer forming step of forming at least one metal layer on an upper surface of the resin layer; a contact step of pressing the metal layer into contact with the upper surface of the internal connection terminal and thereby making the upper surface of the internal connecting terminal flat; a bonding step of bonding a portion of the metal layer provided in contact with the internal connecting terminal to the internal connecting terminal after the contact step; and a wiring pattern forming step of patterning the metal layer to form the wiring pattern after the bonding step, wherein the metal layer and the internal connecting terminal are bonded to each other by at least one method of a group including a laser welding method and a resistance welding method at the bonding step.
