Abstract:
1. A bonding pad, comprising: a pad trench formed in an insulating film and connected to an interconnection trench formed along a surface of said insulating film a protrusion formed by a portion not removed of said insulating film in said pad trench to decrease a substantial opening area of said pad trench; a conductive film buried in said pad trench to form a bonding pad and connected to a semiconductor element through said interconnection trench; and a contact hole formed within said pad trench at a position near said protrusion to electrically connect said conductive film to a further conductive film formed below said insulating film within said pad trench, wherein said contact hole and said further conductive film substantially suppress an increase in electrical resistance in said pad trench due to formation of said protrusion.
