Abstract:
1. A semiconductor device, comprising: a semiconductor substrate; an oxide film formed on the semiconductor substrate; an electrically-conductive non-water-permeable film formed on the oxide film; a bonding pad formed above the electrically-conductive non-water-permeable film through intermediation of an inter-layer insulation film, the bonding pad being smaller than the electrically-conductive non-water-permeable film; a metal interconnecting line configured to connect the bonding pad to an internal circuit; an outer circumferential interconnecting line surrounding the bonding pad and formed above the electrically-conductive non-water-permeable film, the being separated from the bonding pad; and a contact formed along an entire circumference of the outer circumferential interconnecting line, the contact electrically connecting the outer circumferential interconnecting line to the electrically-conductive non-water-permeable film and dividing the inter-layer insulation film into an inside portion and an outside portion of the contact.
