Abstract:
1. A semiconductor device comprising: a semiconductor substrate; an electrode pad disposed on the semiconductor substrate; a first insulating layer disposed on the electrode pad and the semiconductor substrate; the first insulating layer having a first opening directly over the electrode pad; first wiring disposed on the first insulating layer, the first wiring being directly coupled to the electrode pad through a conductor via formed in the first opening; a second wiring disposed on the first insulating layer, the second wiring is disposed perpendicularly to the first wiring; a second insulating layer disposed on the first wiring, the second wiring and the first insulating layer, the second insulating layer having a second opening overlying a portion of the first wiring; a metal film disposed on the first wiring in the second opening and on a part of the second insulating layer; and a solder bump overlying the metal film, wherein the second wire passes through under the metal film.
