Patent number: 8338288Abstract: In connection with a semiconductor device in which a conductive member is coupled to the surface of a bonding pad exposed from an opening formed in a passivation film, there is provided a technique able to suppress the occurrence of a crack in the passivation film. A second planar distance between a first end of an electrode layer and a first end of a pad is greater than a first planar distance between the first end of the electrode layer and a first end of an opening. Since the second planar distance between the first end of the electrode layer and the first end of the pad is long, even when a coupled position of wire is deviated to the first end side of the electrode layer, stress caused by coupling of the wire to a stepped portion of the electrode layer can be prevented from being transmitted to the first end portion of the pad.Type: GrantFiled: April 6, 2011Date of Patent: December 25, 2012Assignee: Renesas Electronics CorporationInventors: Tamaki Wada, Akihiro Tobita, Seiichi Ichihara
