Abstract:
A method of manufacturing a semiconductor integrated circuit device having a metal wire between an electrode part before rearrangement being a part of a top-layer wire and a bump electrode working as an external terminal, the method comprising steps of:(a) forming the top-layer wire that extends on a semiconductor substrate and an insulation film that is formed on the top-layer wire and that exposes the electrode part before rearrangement being a part of the top-layer wire; (b) forming a photocurable resin layer on both the insulation film and the electrode part before rearrangement; (c) irradiating a laser beam onto a peripheral portion of an area scheduled for forming the metal wire, which extends from the electrode part before rearrangement to a contact area of the bump electrode, and curing the photocurable resin layer by scanning; (d) forming a guide layer made of the cured resin part, in which the metal wiring formation scheduled area has a hollow shape, by removing an uncured portion of the photocurable resin layer; (e) forming the metal wire that extends from the electrode part before rearrangement to the bump electrode contact area, by performing plating in a hollow-shaped part along the guide layer; and (f) forming the bump electrode on the bump electrode contact area of the metal wire.
